This has to do with using pipe() and grep and read.csv() I have a .csv file
that I grep using pipe() and read.csv() as follows: read.csv(pipe('grep foo
bar.csv')) However, is there a way to have this command run when for example,
there is no "foo" text in the bar.csv file? I get an error message
(appropriately): Error in read.table(file = file, header = header, sep = sep,
quote = quote, : no lines available in input Is there a way to "inspect" the
output of pipe before passing it on to read.csv()? Thanks,
