Dear All, Within a large script, I try to invoke a second program (called e.g. XXX) from R using "shell" or "pipe".
e.g.: > readLines(pipe("XXX")) or: > shell("XXX",intern=TRUE, wait = TRUE) After running the program, the script reads a file with solutions produced by the second program ("XXX.001"). > readLines("XXX.001") This works fine, when the second program finishes quickly. However, when it takes some more time (like 2 minutes) R does not wait and starts looking for XXX.001 which is not there (yet). Consequently,my beautiful script crashes..... Is there a way to let R wait until the second program really finishes?? the argument "wait = TRUE" obviously doesn't work... thanks uin advance, Robbert -- View this message in context: http://n4.nabble.com/Pipe-shell-R-does-not-wait-tp1458692p1458692.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
