bricas / statistics-r

The below commands should be equivalent, but the latter causes an error. Seems like this is because wrap_cmd adds on a semicolon without checking to see if an actual command proceeds it:

statistics-r/lib/Statistics/R.pm

Line 810 in f5dbc80

$cmd .= qq`; write("`.EOS.qq`",stdout())\n`;

. Otherwise, very useful module 👍.

use Statistics::R;

my $R = Statistics::R->new();

$R->run(qq{
   a = 1;
   b = 2;});  # no error

$R->run(qq{
   a = 1;
   b = 2;\n\n});   # error because of newline

The output is

Problem while running this R command:

     a = 1;
     b = 2;


Error:
unexpected ';' in "  ;"
Execution halted

Trailing newline causes R Error
