[R] reading file in zip archive

Hi List I have a series of zip archives each containing several files. One of these files is called goCats.txt and I would like to read it into R from the archive. It's a simple tab delimited text file. pathToZip <- '/home/iain/Documents/Work/Results/bovineMacRNAData/deAnalysis/afInfection/comm

Re: [R] problem with ifelse

Hi, The error with ifelse() seems to be that you have no idea what ifelse() does. As far as I can tell, you tried to construct code that does something like this: y<-function(tdata,v){ z <- rep(NA, length(tdata)) s <- z for(i in 1:length(tdata)) { for(j in 1:length(v-1)) {

Re: [R] reading file in zip archive

Iain - Once you specify the file to unzip in the call to unz, there's no need to repeat the filename in read.table. Try: z <- unz(pathToZip, 'goCats.txt', 'r') zT <- read.table(z, header=TRUE, sep='\t') (Although I can't reproduce the exact error which you saw.)

Re: [R] reading file in zip archive

Hi Phil Thanks, but this still doesn't work. Here's a reproducible example (was wrapping my head around these functions before). x <- as.data.frame(cbind(rep('a',5), rep('b',5))) y <- as.data.frame(cbind(rep('c',5), rep('d',5))) write.table(x, 'x.txt', sep='\t', quote=FALSE) write.table(y, '

Re: [R] problem with ifelse

Since your code has things like this: z<-numeric(length(t (( either you have a serious problem with your email client or you need to reread some introductory material and take a hard look at your code. Also note that g() doesn't work, because it contains the statement return(m) but m is undefined

[R] Survival with different probabilities of censoring

Dear all I have a fairly funky problem that I think demands some sort of survival analysis. There are two Red List assessments for mammals: 1986 and 2008. Some mammals changed their Red List status between those dates. Those changes can be regarded as "events" and are "interval censored" in the sen
