In what medium are you measuring the size of the image?
If you're reading on screen, try reading the help page for ?windows, where it
says
"The size of a window is computed from information provided about
the display: it depends on the system being configured accurately.
By default a screen device asks Windows for the number of pixels
per inch. This can be overridden (it is often wrong) by
specifying ‘xpinch’ and ‘ypinch’"
... and rather more.
Broadly, though, you are generating a vector image of defined size in some
medium. There is no meaningful pixel count until you use a raster device to
display it, and when you do, the size depends entirely on what the device
thinks its pixel size is. And it seems that windows is not often right about it.

Re: [R] Problems updating packages
I recommend using a personal library directory unless you really are an administrator of a computer that multiple users of R use (very unusual for Windows). The install program offers you the opportunity to create an R/win-library/ directory. If you do this and make a habit of never updating "As Administrator" then you won't have to worry about permissions getting screwed up. This strategy actually works quite well on Linux as well, and I imagine would be a good strategy on any OS. The only thing you would need to elevate permissions for is to upgrade R, and Windows UAE will prompt you for that when you run the install. --- Jeff NewmillerThe . . Go Live...

Re: [R] subest a data set on two conditions
Hi,
Try:
#Eitherindx <- which(df$pvalue <0.05)
indx1 <- sort(c(indx,ifelse(!indx%%2,indx-1,indx+1)))
df[indx1,]
#or
df[!!with(df,ave(pvalue,((seq-1)%/%2)+1,FUN= function(x) any(x <0.05))),]
A.K.
How can I subset the example data set based on pvalue ( <0.05) and also include
the set of each pairs?
I could subset with this code a<-subset(df, pvalue <0.05) whcih would give me
this output

Re: [R] rJava problems
You don't really provide enough information like R.Version() but my guess is that you are running 64-bit R either directly or through R Studio but that you have only 32-bit Java installed. I am doing fine on Windows with Java 7 update 45 but had some 64-bit run issues with only Java 7 update 40 64-bit JDK.

[R] R, RStudio, Rcpp Appreciation
Many times we [devs & users] get into a zone and go on extended binges into our own projects neglecting the niceties of society. Then, while either still on a particular path or even when we reach our destination, we don't directly state our appreciation for those special individuals whose projects and interests make our own possible. Consider this as such a statement. Thank you, not only for the work you share and the effort you give but also for the ability you give to others. And, in closing I just want to say...

Re: [R] How to evaluate sequence of strings like this
Hi,
You could do without "eval(parse(.."
mydat <-
data.frame(Centercode=letters[1:5],FSUSN=letters[6:10],Round=letters[11:15],stringsAsFactors=FALSE)
mydat1 <- paste(mydat$Centercode, mydat$FSUSN,mydat$Round,sep="")
mydat2 <- as.character(interaction(mydat,sep=""))
identical(mydat1,mydat2)
#[1] TRUE
#or
mydat3 <- do.call(paste0,mydat)
identical(mydat1,mydat2)
#[1] TRUE
A.K.

[R] growth curve estimation
Dear Community,
I am struggling with a growth curve estimation problem. It is a classic BMI
change with age calculation. I am not an expert of this field but have some
statistical experience in other fields.
Of course I started reading classical papers related to the topic and
understood the concept of the LMS method. After that I thought it will be a
"piece of cake", R must have a package related to the topic, so I just need the
data and I am just a few lines of code from the results.
I encountered some problems:
- found at least three packages related to LMS: gamlss, VGAM and an old one
lmsqreg (I did not try this because it does not support my R version (3.0.1.))
- it was relatively easy to get plots of percentiles in both packages, although
they were far not the same (I also tried an other software, LMSchartmaker it
gave different results from the previous ones)
- I tried to get tables of predicted values (with the predict function in VGAM
and with centiles.pre in gamlss) but without any success.
- I tried to use the function gamlss() instead of lms() in gamlss but I could
not force them to give the same (or very similar results), but the
centiles.pred() function did work as expected for the model resulted from
galmss()
- lms gives really different results if k is specified different ways, which is
"best"?
Also I have a general question: some publications state they estimated the
centiles so that aroun 18 years of age the curves pass through certain points.
How is that possible?
Thank you for any suggestions or insights about the methods or preferred
package!
Here is my code (without data):
#gamlss
library(gamlss)
library(VGAM)
library(foreign)
adatok <- read.spss("MDSZ adatok.sav", to.data.frame=TRUE)
