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.)

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/commonNorm/twoHrs/af2hrs.zip'
z <- unz(pathToZip, 'goCats.txt', 'r')
zT <- read.table(z, 'goCats.txt', header=T, sep='\t')
Error in read.table(z, "goCats.txt", header = T, sep = "\t") :
? seek not enabled for this connection
The same error arises with readLines.
Can anyone advise?
Best
