Your sample data only contains NoD.rg & nPDR.rg. To start with, I think
we need some representative data supplied in dput format just as I supplied
an "mds" dataset. If I understand your mds$col statement correctly there
is only 22 rows of data. Just issue the command "dput(mds) and copy the
output into your e-mail. This will allow R-help readers to use the exact
same data set that you have on your computer.

Well no I cannot because I am still trying ta figure out where "d1 and d2
came from or why you need that loop. It looks like you are renaming the
columns in "mbs" three times but why? And why do it in a loop?
If all that you are doing is renaming the columns from the "ar_diff" data
set names just do it once,
colnames(mds) <- c("Dim.1", Dim.2, Dim.3) before you even create the
"cols" column.
We really need to see the data.
I have never used library("ggpubr") and I cannot see why cols is appearing
in the legend---well it does with my data set. Actually, given my version
of the data set I don't see why it it printing the graph.
Also do you really want all three grcaphs in one .pdf file?

Re: [R] scatter plot
Hello,
In the loop, try filtering out the values you do not want.
Any of
print(ggscatter(mds %>% dplyr::filter(cols != "NoD.rg"), etc))
print(ggscatter(subset(mds, cols != "NoD.rg"), etc))
tmp <- mds %>% filter(cols != "NoD.rg")
print(ggscatter(tmp, etc))
The first two will create a temporary df, the 3rd a permanent one.
Remove it after the loop:
rm(tmp)
Hope this helps,

Re: [R] scatter plot
Hi,
Thanks for getting back to me. I need to have there two groups:
"nPDR.rg and "PDR.rg"
can you please let me know how my loop would look like just with those
two groups?
Thanks
Ana

Re: [R] scatter plot
I must admit that I do not understand what you are doing but can you notm

Note I am using a data.frame not a tibble. It would be helpful if you

[R] scatter plot
Hello,
I have a code like this:
mds <- (ar_diff) %>% dist() %>% cmdscale(k=3) %>% as_tibble()
mds$cols <- as.factor(c(rep("nPDR.rg",7), rep("PDR.rg",8), rep("NoD.rg",7)))
pdf(file = "RG.pdf")
for (dim1 in 1:2){
for (dim2 in (dim1+1):3){
d1 = paste0("Dim.",dim1); d2 = paste0("Dim.",dim2)
colnames(mds)[c(dim1,dim2)] <- c(d1,d2)
print(colnames(mds))
print(ggscatter(mds, x = d1, y = d2, color ="cols" ,size=3
,palette=c("blue","red","green")))
}
}
dev.off()
How do I run the same plot but excluding NoD.rg? What do I need to

[R] scatter plot coloring problem
Hello: I have two data frames (subsetted from a larger one). I am plotting scatterplots with ggplot2 and coloring by different variables. When using one of the variables "Error" with one of the dataframes "conv_df" only a single color is displayed. All the other variables show colors as expected, and when applying the same ggplot() functions to the second dataframe, colors are correctly applied for all variables. I'm scratching me head over this for some time. Maybe someone can see what I'm missing? My repex is attached Thanks -- Micha Silver Ben Gurion Univ.

Re: [R] scatter plot of numerical variables against different sample ids
You can also try using ggplot2 to generate the plot:
> library(tidyr)
> library(ggplot2)
> data <- gather(mldf,Element,Value,2:4)
> p <- ggplot(data,aes(x=factor(Element),y=Value,group=Sample,color=Sample))
> p+geom_line()

Re: [R] scatter plot of numerical variables against different sample ids
Hi Maria,
What happens is that R plots with boxplots (explaining the horizontal
lines, i.e. boxes with n=1) when the x-variable is a factor.
What you can do is transform your Sample column into numeric and then
plot it, with some adjustment of axis labels.
For example:
datf <- data.frame(Sample=c("M1","M2","M3","M4","M5"),
Cu=c(1,2.5,1.15,2,8), Zn=c(5,11,11,4,15), Mn=c(10,8,12,30,35))
datf$Sample2 <- as.numeric(datf$Sample)
with(datf, plot(Sample2, Cu, type="l", lty=1, col="red", xaxt="n"))
axis(1, at=datf$Sample2, labels=datf$Sample)
It might not be the easiest/best approach though... Someone here might
have a better idea.
HTH,
Ivan

[R] scatter plot matrix with multiple trend lines and p values
I am trying to create a scatter plot matrix in which the lower panels
contain
scatter plots colored by group with trend lines by group, and the upper
panels contain r and p values. Using pairs() I was able to get close (ie,
scatter plot matrix on bottom with one trend line and correlation
coefficients and p values in the upper panel) but was unable to add two
lines. Using spm() I was able to get the multiple trend lines, but not the
upper
panel statistics. Does anyone know of a way to accomplish this?
My code using pairs:
pairs(~Sepal.Length+Sepal.Width+Petal.Length+Petal.Width, data = iris,
bg=c(red,blue,green)[iris$Species],
pch = 22,
lower.panel =my_line - function(x,y,...){
points(x,y,...)
abline(a = lm(y ~ x)$coefficients[1] , b = lm(y ~ x)$coefficients[2] ,
...)
},
upper.panel = panel.cor - function(x, y, digits = 2, cex.cor, ...)
{
usr - par(usr); on.exit(par(usr))
par(usr = c(0, 1, 0, 1))
# correlation coefficient
r - cor(x, y)
txt - format(c(r, 0.123456789), digits = digits)[1]
txt - paste(r= , txt, sep = )
text(0.5, 0.6, txt)
# p-value calculation
p - cor.test(x, y)$p.value
txt2 - format(c(p, 0.123456789), digits = digits)[1]
txt2 - paste(p= , txt2, sep = )
if(p0.01) txt2 - paste(p= , 0.01, sep = )
text(0.5, 0.4, txt2)
})

Many thanks David,
I will have a look on logistic regression for my case.
Do you know about a good example regarding logistic
regression ?
I was thinking also of using Multiple Factor Analysis too
(MFA - like in
FactoMineR). However I am not sure how successful this is
going to be.
Best,

Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hi, is it possible to add exposures to a glm with
family=binomial()?
It's easy to do it for a Poisson/negative binomial: just
multiply the
mean by the exposure, that is, offset(log(exposure)): but
this obviously
wrong for a binomial/Bernoulli since the mean must be no
bigger than 1.
My goal was do it it with pscl::zeroinfl and pscl::hurdle,
but answering
for binomial/Bernoulli would already help.

A contour plot of values associated with the points, or a contour plot of the density of the points? For the former, I think you want to use the akima package; for the density estimate, you could use kde2d from the MASS package. In either case, you need to compute the values of the function on a grid, then the contour() function can plot it.

Re: [R] scatter plot to contour plot
In addition to the other responses, I'd like to suggest:
help.search('contour', package='graphics')
Since the graphics package comes with R, you don't necessarily need any
additional package for contouring. But you will need the akima package for
interpolation. Assuming you're doing a contour plot of values associated
with the points, as Duncan put it.

Re: [R] Scatter plot with error bars
Are you sure, you want to calculate 68% confidence intervals? Use the add-argument in ?errorbar to add to the previous plot. errbar(x2,y2,y2+1.96*SD2, y2-1.96*SD2, col=green,pch=19, add=TRUE) Best, Nello -Original Message- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of beginner Sent: Freitag, 28.

Re: [R] scatter plot matrix with different x-y variables
Greg, the pairs2 function was exactly what I wanted. Thanks for a very useful function. May I ask a follow up question, is it possible to draw a correlation line with R2 values for each graph on each graph, or on the side of the graph. I am sure this is possible somehow, but I am new to R programming so please just direct me into the right direction. John, the grid.arrange() function is useful too but not exactly what I needed.

Re: [R] scatter plot matrix with different x-y variables
Several ways but I find that grid.arrange in the gridExtra package combined with ggplot2 to draw the actual graphs works nicely. You might also want to look mfcol or mfrow in ?par ### quick and dirty example of ggplot2/gridExtra library(ggplot2) library(gridExtra) mdat - data.frame(a= 1:5, b=1:5) ndat - data.frame(x = rnorm(20), y = rnorm(20)) p - ggplot(mdat , aes(a,b, colour = 'red' )) + geom_point() + theme(legend.position=none) p q - ggplot(ndat , aes( x, y )) + geom_line() q grid.arrange(p, q) ### I imagine that you will need to install the ggplot2 and gridExtra packages.

For example, here is the code to load and plot my Mammoth Cave rainfall pH data #Load data from web page data - read.csv(http://doylesdartden.com/Monthly-pH-example.csv;, sep=,) attach(data) #Plot data plot(Year,MC.pH,pch=*,col=blue) # Apply loess smoothing y.loess - loess(y ~ x, span=0.8, data.frame(x=Year, y=MC.pH)) # Compute loess smoothed values for all points along the curve y.predict - predict(y.loess, data.frame(x=Year)) # Plots the curve. lines(Year,y.predict,lwd=3,col=blue) #Done What I would like to do is to have it plot the MC.pH data vs. year and the MV.pH vs. year data and then draw two different smoothed lines for the data. This way I could really just look at the two smoothed lines and see how the data is trending in relationship to each other. Thanks David On Mon, Apr 23, 2012 at 11:40 PM, R.

Re: [R] Scatter plot / LOESS, or LOWESS for more than one parameter

Re: [R] Scatter plot - using colour to group points?
Hello all, Yesterday I wrote Michael Weylandt to ask for some help in understanding a line of code he used responding to SarahH's query about controlling colours in scatter plots. He wrote an excellent explanation that deserves to be shared here. Below I include the code I wrote while experimenting with the problem (indicating the specific line of code I asked him about) followed by Michael's thoughtful reply. Saludos - Ian -- Ian G. Robertson Department of Anthropology Building 50, 450 Serra Mall Stanford University, CA 94305-2034 e:i...@stanford.edu #the code: ## x1 - rnorm(13) y1 - rnorm(13) #these two lines from R. Michael Weylandt X = letters[c(1,2,3,3,1,2,1,3,3,1,2,2,1)] colX = c(red,green,blue)[as.factor(X)] #?? How does this work? Ask RMW table(colX) plot(x1, y1, col=colX, pch=20, cex=2) ## #Michael Weylandt's explanation: In short, there are two key bits to follow: 1) What happens when you factorize something -- R stores factors internally as integers with special labels and a few special behaviors for some calculations that won't come up here: the labels aren't so important for our purpose, but the key is that each unique value of X gets assigned to its own factor. The order that they appear in X corresponds to the integers they get, not their real values (if they were already integers or doubles). As a side point this means that floating point trouble can sometimes show up so if you want to bin real numbers, it's safer to use cut() for the factoring step. 2) What happens when you use a factor to subset -- R simply tosses out the factor-ness and only uses the internal integer representation. If we wanted to be more explicit, we'd write colVec[as.integer(as.factor(X))] but the as.integer happens automatically. So the whole path is: assign integers to each unique value of X and subset by those integers: if there are as many unique values as there are elements of the color vector, the end result is a direct matching: if there are too many, it throws and error: too few and some colors go unused: something like: col(red,green,blue)[as.factor(letters[1:4])] ## ERROR col(red,green,blue)[as.factor(letters[1:2])] ## blue not used.

There's also the lines() command which takes a col argument if you want to do multiple lines (I usually wind up wrapping it in a for loop though there might be something smarter) ggplot2 is great, though the learning curve is a little rough: you can get good help here but if you go down that path, there's also a dedicated ggplot2 list that's worth checking out.

I wanted to up a colour scheme to match the site, so tried BG1 - blue EA7 - green before the plot function, but the graphic just came out with red and black as before.

Re: [R] Scatter plot - using colour to group points?
I think the easiest way to do this is to set up a color vector with ifelse and hand that off to the plot command: something like col = ifelse(TEMP3[,SITE] == BG1, blue, green) # Syntax is ifelse(TEST, OUT_IF_TRUE, OUT_IF_FALSE) For more complicated schemes, a set of nested ifelse()'s can get you what you need.

Re: [R] Scatter plot - using colour to group points?
Another approach would be to use ggplot2.
Code can look a bit daunting to begin with but ggplot2 is a
very versitile graphing package and well worth learning.
Simple example
=
library(ggplot2)
mydata - data.frame(site=c(A,A,A, B,B,B), time1 = 1:6,
t1=c(23,24,13,7,19,12),
t2=c(7, 4,6,8,5,9))
p - ggplot(mydata, aes(x=time1)) +
geom_point(aes(y= t1, colour= site)) +
geom_point(aes(y = t2, colour=site))
p - ggplot(mydata, aes(x=time1)) +
geom_point(aes(y= t1, colour= site)) +
geom_point(aes(y = t2, colour=site))
p - p + scale_x_continuous('Time')+
scale_y_continuous('Temperature')
p

Dear All,
I am very new to R - trying to teach myself it for some MSc
coursework.
I am plotting temperature data for two different sites over
the same time
period which I have downloaded from a university weather
station data
archive.
I am using the following code to create the plot
plot ( x = TEMP3[,TIME], y = TEMP3[,TEMP], type = p,
col =
TEMP3[,SITE], pch = 3, main = Temperature changes, xlab
= Date, ylab =
Temberature[C])
I managed to use col = TEMP3[SITE] to plot the two
different sites( BG1
and EA7) in different colours, but I am struggling to
change the colours.
I wanted to up a colour scheme to match the site, so tried
BG1 - blue
EA7 - green
before the plot function, but the graphic just came out
with red and black
as before.
There are other datasets in which there are more than two
sites so I would
really like to learn how to use colour to distinguish

Re: [R] Scatter plot - using colour to group points?
I don't think you can do different colors for a single line (not an ifelse thing, just a what would that mean sort of thing), but a plot type like b o or h will work the same way.

Re: [R] Scatter Plot Command Syntax Using Data.Frame Source
Hi,
Below are a couple of options using a standard dataset,
str(iris)
## using base graphics
d - split(iris, iris$Species)
str(d) # list of 3 data.frames
par(mfrow=n2mfrow(length(d))) # split the device in 3 plotting regions
b.quiet - lapply(names(d), function(x) { # loop over the list names
with(d[[x]], plot(Sepal.Length, Petal.Length))
title(x)
})
library(ggplot2)
# using facetting
ggplot(iris) + facet_wrap(~Species) +
geom_point(aes(Sepal.Length, Petal.Length))
library(lattice)
# using facetting
xyplot(Petal.Length ~ Sepal.Length | Species, data=iris )

Re: [R] Scatter plot produces 'x' and 'y' lengths differ
It likely means that your x and y are differently long. That is, affect1 and adh1scr do not contain the same number of values in that instance. That precludes them from being plotted against each other. abline and lowess would fail for the same reason. x-c(1,2,3) y-c(2,4) plot(y~x) complete.cases(x,y) However, what is peculiar about this is that if x and y indeed have different length, the complete.cases() function should fail (unless specified with some override argument). The problem is definitely NOT one with XLIM or YLIM. HTH, Daniel Alspach, Steven E. wrote: Hello, I am working on a project to create some scatter plots.

Re: [R] Scatter plot with multiple data sets
Hi Joe, The easiest option will be to combine all 6 datasets (at least the variables you want to use in your scatter plot), and then create another variable that indicates to which group the observations belong. Here is a small example of what you might do once your data are all together (obviously replace mtcars with your dataset name and the variables with your variables): with(mtcars, plot(x = hp, y = mpg, pch = carb)) I am also fond using the ggplot2 package for graphs. require(ggplot2) ggplot(mtcars, aes(x = hp, y = mpg, shape = factor(carb))) + geom_point() Cheers, Josh On Thu, Mar 3, 2011 at 12:03 PM, Jorseff jcp...@york.ac.uk wrote: Hi, I have multiple (6) data sets which I would like to plot together on one scatter graph.

Re: [R] Scatter plot using icons (from a gif) instaed of points - is it possible ?
Hi, You'll probably find that there are two parts to your query: 1- import a bitmap into R, for this I'd suggest the wiki page, http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-misc:display-images 2- place the image (now some sort of matrix of colour points) at different locations on a graph. I don't know any function to do this (*) (but there may be some listed in the above webpage). Another option is to convert the bitmap to vector graphics using an external tool, then use the grImport package to create a grob (graphical object) that you can then place in any Grid-based plot (there is an example with lattice). HTH, baptiste (*) this may look like a starting point: http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-grid:displaybitmap 2009/10/14 Tal Galili tal.gal...@gmail.com: Hello dear R-help group.

Re: [R] Scatter Plot
please Cc. the list next time
Two suggestions,
1) read the help page, e.g. ?points would have told you why pch=10
produces 1.
2) Try the following and see which you prefer,
x = y = labels = 1:20
?text
plot(x, y, type='n') # empty plot
text(x, y, paste(labels))
library(ggplot2)
?qplot
qplot(x, y, geom=text, label=labels)
library(lattice)
?xyplot
xyplot(y~x, t=n,
panel = function(...) { panel.text(..., label= labels) } )

In STATA I can do so by twoway (scatter x rho, mlabel(id)) How can I do the same in R? I am sure there is some simple way to do this.

[R] scatter plot using ggplot
I used ggplot to create a scatter plot : library(ggplot) library(mnormt) Sigma = matrix(c(1, 0.6, 0.6, 1), 2, 2) x = rmnorm(20, c(0,0), Sigma) xx = x[order(x[,1]),] y = xx[,1] z = xx[,2] qplot(z, y, type=point, main=x-y plot, xlab=x, col=blue) However I want following: 1. Plot color must be Blue (where it is displaying as red) 2. There should not be any color platted 3. Plot size must be larger than what it is displacing Can anyone please tell me how to do that?

Use ggplot() instead: ggplot(data.frame(y,z), aes(y, z)) + geom_point(colour = blue) + scale_x_continuous(x) + opts(title = x-y plot) 3. Plot size must be larger than what it is displacing Make the window bigger?

Re: [R] Scatter plot transparency
Please see the footer of this message. What do you want to be transparent, and what did you use to try to get it (there are many possibilities)? What OS and version of R is this? Note that the default value of bg for the png() and tiff() devices is white, and the Windows version of the tiff() device does not support transparency. But png(bg=transparent) does give a transparent background.

Thanks, I think I've got it on Mac. Will try with my windows station tomorrow. Best, Anh Tran On Jun 21, 2008, at 12:05 AM, Prof Brian Ripley wrote: Please see the footer of this message.

Re: [R] Scatter plot transparency
Hi Anh, I don´t know if I understood your point fine. I generate a scatterplot, and open it on adobe photoshop 7.0 with tranparent background. setwd(c:\\temp) x-runif(100) y-rnorm(100) png(transparent_scatterplot.png, 800, 600, bg=transparent) plot(y~x) dev.off() I hope this help, miltinho Brazil On 6/20/08, Anh Tran [EMAIL PROTECTED] wrote: Hi all, I'm putting a few plots together and wondering what format would be best to export a few scatter plots to Illustrator to make a figure.

[R] Scatter Plot - 3 vectors side by side
Hi, I have 3 vectors, x=rnorm(10); y=rnorm(20); z=rnorm(30). I would like to plot 3 vectors side by side (like a bar plot) with scatter plot something similar to the following: .. *** ;;; .. ** ;;; .. *** ;;; .. *** ;;; ... *** ;; x y z How can I do this with Plot()? Thanks in advance.
