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()

Hi Maria,
Perhaps something like this:
mldf<-read.table(text="Sample Cu Zn Mn
M1 1 5 10
M2 2.5 11 8
M3 1.15 11 12
M4 2 4 30
M5 8 15 35",
header=TRUE)
matplot(mldf,type="b",pch=c("C","Z","M"))

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

Dear all
I know that my question is very simple but although I tried to find an answer
online, I couldn't and I am stuck.
I have a dataset of three numerical variables measured in different samples ID.
Something like this:
SampleCuZnMnM1 1 5 10M2
2.5 11 8M3 1.15 11 12
M42 4 30M5815
35
I would like to plot these variables (Cu, Zn, Mn) (in y-axis) against the
Sample ID (in x-axis) in a scatter plot with lines as I want to see how they
change in the samples.
I tried using the command>plot(Sample, Cu, type="l", lty=1, col="red")
but I wouldn't get a line. Actually, I would get some small horizontal lines in each
point. I tried to use type="p" but I would get the same thing.
I would very much appreciate if you could help me on that. Apparently, I am
missing something.
Thank you in advance.
Kind regards,Maria

[R] scatter plot of numerical variables against different sample ids
Dear all I know that my question is very simple but although I tried to find an answer online, I couldn't and I am stuck. I have a dataset of three numerical variables measured in different samples ID.

I tried using the command>plot(Sample, Cu, type="l", lty=1, col="red") but I wouldn't get a line. Actually, I would get some small horizontal lines in each point.
