Hi,
is possible to make a R script to run under a console without open the R
environment?
Something like this example.R
#!/usr/bin/R
function(name="Put here your name") {
print(name)
}
In a console I make
./example.R name="Ronaldo Reis J?nior"
then program print my name.
It is possible?
Thanks
Ronaldo
