pass data from Perl to R -


i want pass following data perl r , rescaled them (scale [0, 1] ) in r rescaler function , send them perl.

$m1 = 4; $m2 = 5.3; $m3 = 2;  $m4 = 1;  $m5 = 1.3;  $m6 = 2;

i did:

my $r = statistics::r->new() ; $r->startr ;  $r->set('data', $m1 . ',' . $m2 . ',' . $m3 . ',' . $m4 . ',' . $m5 . ',' . $m6); $r -> run(q` library(reshape); scaled_data <- rescaler(data, type="range"); `); $scaled_data = $r -> get('scaled_data'); print $scaled_data,"\n",$data,"\n"; $r->stopr();

but following error. 

problem while running r command:  library(reshape); scaled_data <- rescaler(data);    error: x - mean(x, na.rm = true) :   non-numeric argument binary operator calls: rescaler -> rescaler.default in addition: warning message: in mean.default(x, na.rm = true) :   argument not numeric or logical: returning na execution halted

1) how can pass data correctly? 2) think approach, code work slowly, need send data r rescaling?

@len jaffe , @mrflick

i tried :

my $r = statistics::r->new() ; $r->startr;  $r->set('data', [ $m1 , $m2 , $m3 , $m4 , $m5 , $m6 ] ); $r -> run(q`library(reshape);scaled_data <- rescaler(data)`); $scaled_data = $r -> get('scaled_data'); print $scaled_data,"\n"; $r->stopr();

i got :

array(0xdde3d0)

are sure don't want:

  $r->set('data', [ $m1 , $m2 , $m3 , $m4 , $m5 , $m6 ] );

that's how set commands documented in perldoc statistics::r
