* Getting Started

** Batch Mode

#+begin_src R :exports code

pdf("xh.pdf") # set graphical output file
hist(rnorm(100)) # generate 100 N(0,1) variates and plot their histogram
dev.off() # close the graphical output file

#+end_src

If we put the code above in a file called =z.R=, we can execute the
code from the command line via: =R CMD BATCH z.R=

#+begin_src R

  x <- c(1, 3, 5)

#+end_src


#+begin_src R

  x[3]

#+end_src


#+begin_src R

  q <- c(x,x,8)

#+end_src


#+begin_src R

  x

#+end_src
