dear All, I am using the DNA copy package to get my CGH files (Agilent 244K arrays) analysed. I am using this command to plot them one by one : >plot(CNA.object, plot.type="w") This is a very slow and time consuming process and I have ~60 files to plot . I am quite novice in R and was wondering whether anybody could advise on a simple script to get all files plotted and the plots saved into a single pdf file ( or nay other format)?

Here is an example of making 3 pdf plots. It consists of a loop, marked off with curly brackets, executed for the variable i, which ranges from 1 to 3. The file names are 1.pdf, 2.pdf, and 3.pdf, generated using the R paste function. The data are two sets of 10 random numbers, generated by rnorm. The pdf function creates the output, but in order for it to write out the final result, you need to call the dev.off function. for(i in 1:3){ pdf(file=paste(i,"pdf", sep='.')) plot(rnorm(10), rnorm(10)) dev.off() } Best, Tom On Apr 6, 2011, at 6:45 AM, Nathalie Conte wrote: > dear All, > I am using the DNA copy package to get my CGH files (Agilent 244K > arrays) analysed. > I am using this command to plot them one by one : > >plot(CNA.object, plot.type="w") > This is a very slow and time consuming process and I have ~60 files > to plot .

pdf() supports multiple pages so if you do pdf(file = "tmp.pdf") plot() plot() plot() dev.off() you'll get one pdf file with three pages. Not all devices (example: png()) support multiple pages. Essentially, move the loop inside the pdf() call in the two previous emails.

Hi Nathalie, if I understand correctly, you have 60 DNAcopy object you need to plot. The following code will do the trick: The first step is to create a vector with the name of the 60 objects: object.list <- c("DNAcopy1", "DNAcopy2"..."DNAcopy60") than do a loop to plot them as pdf file: for (I in object.list) { pdf(file=paste(I, ".pdf", sep=""), height=10, width=10) plot(I, plot.type="w") dev.off() } you can modify the height and width in the pdf function to increase or reduce the plot dimensions best r On 6 April 2011 12:45, Nathalie Conte <nac@sanger.ac.uk> wrote: > dear All, > I am using the DNA copy package to get my CGH files (Agilent 244K arrays) > analysed. > I am using this command to plot them one by one : > >plot(CNA.object, plot.type="w") > This is a very slow and time consuming process and I have ~60 files to plot > .
