Hi all,
I am trying to get shell variable(s) into my R script in Linux . How
do I get them?
my shell script is
t1.sh
#!bin/bash
Name=Alex; export Name
Age=25; export Age
How do get the Name and Age variables in my R script?
My R script is
test.R
print " Your Name is $Name and you are $Age years old"
My another shell script that call the R script is
test.sh
#!bin/bash
source t1.sh
Rscript test.R
So by running this script ./test.sh
I want get: Your Name is Alex and you are 25 years old
I can define those variables in R but that is not my intention.
Thank you in advance

Do note that for an R function the arguments need to be flanked by parentheses.> > My another shell script that call the R script is > > test.sh > #!bin/bash > source t1.sh > Rscript test.R > So by running this script ./test.sh > > I want get: Your Name is Alex and you are 25 years old > > I can define those variables in R but that is not my intention.David Winsemius Alameda, CA, USA
