Re: [R] X11 graphics windows under CMD BATCH

I had this same issue. My quick and dirty solution was to create an infinite loop at the end of my R plotting script and then manually kill the job with Ctrl+C once I was done looking at the plot. -- View this message in context: http://r.789695.n4.nabble.com/X11-graphics-windows-under-CMD-BATCH-

Re: [R] Parallel Scan of Large File

Hi Jim, Thanks for your insight. I used Linux split to split my large file into smaller partitions. On the server I work on, multipath I/O access is enabled and we use RAID for storage; thus, I don't think I can put each partition on a spindle. I'm able to open multiple files at a time into stdin

[R] Parallel Scan of Large File

Is it possible to parallel scan a large file into a character vector in 1M chunks using scan() with the "doMC" package? Furthermore, can I specify the tasks for each child? i.e. I'm working on a Linux box with 8 cores and would like to scan in 8M records at time (all 8 cores scan 1M records at a

This should work: > test <-subset(wild,ID=="2830" & Date==as.POSIXlt("2010-08-17")) If not, here's another solution: > dates <- c("2010-05-28","2010-08-17") > dates <- as.POSIXlt(dates) > id <- c("2830","2830") > data <- data.frame(id,dates) > test <- data[data$id == "2830" & data$dates == as.POS
