Did some reading and tried the following to exclude certain data columns but my syntax must be slightly off...
> workdir <- '/tmp/data' > for (x in dir(workdir,pattern='.csv$')){ + d <- read.table(paste(workdir,'/',x,sep=''), sep=",", header=TRUE, colClasses=list(#, BlockType, ThreadName, BytesSoFar, BlockSize, BlockOffset, BlockStart, BlockEnd, Duration, BytesPerSecond, MBBlockSize, Path=NULL)) + pdf(paste(workdir,'/',sub('.csv$','.pdf',x),sep='')) + plot(d$BlockSeqNum, d$MBs, Error: syntax error in: " pdf(paste(workdir,'/',sub('.csv$','.pdf',x),sep='')) plot" Execution halted gecko951 wrote: > > Jeff's code works beautifully with a couple changes to my dataset.
