Dear R-users,
Is there a way I can ask R to execute the "write("hello
world",file="hello.txt")" command directly from the UNIX shell, instead
of having to save this command to a .R file and execute this file with R
CMD BATCH?
Yes. Some versions of R support the -e option on the command line to
execute a particular command. It's not always easy to work out the
escapes so your shell passes all the quotes through... An alternative
is to echo the command into the shell, e.g.
echo 'cat("hello")' | R --slave
(where the outer ' ' are just for bash).
