Hi list,
I would like to capture the console output of a Perl script by running the
script from R.
I have tried the following:
# Create perl script
cat( 'print "Hello World\n";',file="hello.pl" )
# Trial 1
system(command="c:\\Perl64\\bin\\perl hello.pl")
-I saw no output for the above command. I have used this method before to
run perl scripts that performed tasks, but only now do I want to capture the
perl output from the print command within the perl script
# Trial 2
system(command=paste(Sys.getenv("COMSPEC"),"/c","C:\\Perl64\\bin\\perl
hello.pl"))
- In the help for 'system' in R, it mentions making the above changes if one
wants to pass a command to the cmd on a windows machine.
I am using R 2.9.2 on Windows 7.
I'm doing this since I want to run perl scripts to find distance measures
between words (Wordnet Similarity perl modules) and capture the numeric
result from the perl script execution back into R. I have heard of RSPerl
but I would greatly appreciate a solution using system. Writing the result
to a file and then reading the file could be a another option, but I'd like
to learn about capturing console output from perl into R.
Any suggestions or hints would be appreciated with much gratitude.
Thanks
Harsh
