Running R on Karle

The following is the "Hello World" program written in R:

# Hello World example
a <- c("Hello, world!")
print(a)

To run R job on Karle server, save your R script into the file (for example "hello.R") and use the following command to launch it:

R --vanilla --slave < helloworld.R

Note that you need to load R module first (see previous section).

Running R on cluster machines
