[BlindRUG] Running the Batch file - no output

[Henrik Bengtsson]

When sourcing and R script from within R using:

    source("practice.R")

or running it in batch mode from the command line using:

    Rscript practice.R

you need to explicitly print objects in order for them to be outputted, e.g.

    print(x)

This also works in interactive mode, but since it is tedious to type, R is
designed to print all objects by default in interactive mode, i.e. typing
'x' plus ENTER at the R prompt is automatically turned into a print(x) by R.

Hope this helps

Henrik
