BATCH                  package:base                  R Documentation

_D_e_s_c_r_i_p_t_i_o_n:

     Run R non-interactively with input from `infile' and place output
     (stdout/stderr) to another file.

_U_s_a_g_e:

     R BATCH [options] infile [outfile]

_A_r_g_u_m_e_n_t_s:

  infile: the name of a file with R code to be executed.

 options: a list of R command line options, e.g., for setting the
          amount of memory available and controlling the load/save
          process. If `infile' starts with a `-', use `--' as the final
           option.

 outfile: the name of a file to which to write output.  If not given,
          the name used is the one of `infile', with a possible `.R'
          extension stripped, and `.Rout' appended.

_D_e_t_a_i_l_s:

     By default, the input commands are printed along with the output. 
     To suppress this behavior, add `options(echo = FALSE)' at the
     beginning of `infile'.

_N_o_t_e:

     Unlike `Splus BATCH', this does not run the R process in the
     background. In most shells `R BATCH [options] infile [outfile] &'
     will do so.
