For the scan function, it makes no difference whether you read from a pipe or a regular file, both are represented by connections in R. Temporary files should be avoided where possible, as they introduce a source of data corruption that may remain unnoticed for quite some time. If your external program can be run by just one command line, use a pipe, as in p = pipe(ls); scan(p, what = character(0)); Full filtering (i.e. if you need to write input into its stdin in addition to reading output from its stdout) is currently not supported by R. I've attempted to provide that, see http://www2.cmp.uea.ac.uk/~jtk/software/ Best regards, Jan -- +- Jan T.

[R] about get stdout from other program
Dear all R-helper, if I want to use stdout from other language as my R program input ,which is the best way for design the API,using Pipe function or produce a temporary file,using scan function to read the file ? thanks Michael __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
