Re: [R] Merging two files together in R

Try looking at ?merge If your data is in two dataframes df1 and df2: merge(df1, df2) (This will merge on SNPID because that column is common to both dataframes). --- -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Morassa Mohseni Sent: 24 August

Re: [R] problem with reading data files with different numbers oflines to skip

Hi Tom It looks as if you are reading in genepix files. I believe the format for the start lines includes a second line to say how many lines to skip. Something like this, specifying 27 lines to skip: ATF 1 27 43 Type=GenePix Results 1.4 DateTime=2003/11/14 17:18:30 If

Re: [R] Previously saved workspace restored

Hi If you enter the command ls()you will see a list of names that have come with the .Rdata file you double-clicked. If you enter one of these names at the command prompt you will see the data. So, for example if you have some data called mydata: ls() [1] mydata repos mydata [,1]

Re: [R] Loop and cbind

Hi In what way does it not work? My guess is that you have not declared your values outside the for loop. As they are local they will be lost on exit. You need to declare them before: ewma-vector(length=12) standard-vector(length=12) for ... { } John Seers --- Hi, I

Re: [R] Repeat if

Hi I think a for loop would be more what you want. Something along the lines of: V-list(a=c(1,2,3), b=c(2,3,4)) # list of 2 vectors for ( i in 1:2 ) { # 2 vectors (replace with 85 ...) print(range (V[i], na.rm = TRUE)) } Regards JS --- -Original Message- From:

Re: [R] autoload libraries at startup

Hi I do not know if this is the best way, but have a look at .Rprofile - a text file that lives in the R root directory ans is executed at startup. You could put library() commands in that. See ?Startup for more information. Regards JS --- John Seers Institute of Food Research Norwich

Hi R guru coders I wrote a bit of code to add a new column onto a topTable dataframe. That is a list of genes processed using the limma package. I used a for loop but I kept feeling there was a better way using a more vector oriented approach. I looked at several commands such as apply, by etc
