Colleagues
Can anyone tell me what R does with local variables when they are passed
in a system call to a shell script?
e.g. I have a string as an R variable called tripcode. I want to pass
this variable in a system call to a local bash script calling gmt
(Generic Mapping Tool) functions:
system("source map_acoustic_transects_and_trawls.gmt", tripcode)
I think this is what is meant in Section 4.6 of Venables and Ripley(?).
When I ECHO the parameter passed into the bash script nothing is returned:
echo "TripCode" $tripcode
TripCode
Is there a way to do this efficiently without writing the string
variable to a file and re-reading it into the shell script?
Thanks for advice,
Sam
