For documentation we use a system that generates Rd files from special comments in the code. (inlinedocs). It is crucial to be able to get the defining source code for objects like methods to extract the comments from it. Here is an R session that shows how this works for several kinds of methods and (at the end of the session) how if fails for methods of "initialize" >

1. When you don't know (or are not sure) what an object is, str() is your friend. 2. My guess is that `lidnames' is a character vector with names. 3. If genes.txt has only only column, you might as well use: mygenes <- scan("genes.txt", what="") which reads the data into mygenes as a character vector. Then your command should work. [read.table() returns a data frame. You index mygenes, a data frame, with a logical vector, which means selecting columns that are TRUE. I suspect my...

Dear Rui, >From my understanding of time-dependent covariates (not an expert but have been working on a similar problem), it would appear that the coding of the status column is not correct. Unless you have observed an event at each interval you should only have status=1 for the last interval. In your example I see 3 in total. Also, I think that if "end" is proportional to your

Hi! All, I am trying to fetch rows from a data frame which matches to first 2 columns of another data frame. Here is the example what I am trying to do: > ptable=read.table(file="All.txt",header=T,sep="\t") > ptable=as.matrix(ptable) > dim(ptable) [1] 9275 6 > head(ptable) Gene1 Gene2 PCC PCC3 PCC23 PCC123 [1,]
