Have you considered in R writing the file to a temporary name (see ?tempfile). When the file is complete, after the dev.off() in R as suggested by Prof Ripley, you could rename the file [using file.name() in R]. Your external program can now access the file without worrying about whether it is complete, since the file appears not to exist until the whole file has been written. efg ______________________________________________ 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
