Hello
I would like to use the source(command) and write the output into a file.
I am using
outputfile=file("output.txt", open="wt")
sink(outputfile, type="output")
source("input.R", echo=TRUE)
Unfortunately the result has prompted commands. How can I avoid the
prompted commands data(iris), ...?
Thanks
