How to run R scripts in batch mode with arguments

Run R script as:

R CMD BATCH --no-save --no-restore '--args 1 c(2,3,4) matrix(c(5,6,7,8),nrow=2)' script.R

The script.R has content:

# This just reads the two arguments passed from the command line
# and assigns them to a vector of characters.
args <- commandArgs (TRUE)
# Here you should add some error exception handling code
# in case the number of passed arguments doesn't match what
# you expect (check what Forester did in his example)

# Parse the arguments (in characters) and evaluate them
vec1 <- eval( parse( text= args[1] ) )
vec2 <- eval( parse( text= args[2] ) )
mat1 <- eval( parse( text= args[3] ) )

# Check
print(vec1) # prints a vector of length 1
print(vec2) # prints a vector of length 3
print(mat1) # prints a 2 x 2 matrix
