I'm trying to read in a CSV file that contains non-numeric data. A
normal PDL can't hold strings, so I figure I must use PDL::Char. I
don't believe this can be used with rcols, but that would be the ideal
situation.
As it is, the solution I've come up with is:
while (<$filename>) {
@temp=split(",",$_);
$t_pdl=PDL::Char->new(@temp);
push
(@file_pl_arr,$t_pdl);
}
$file_array=pdl(@file_pl_arr);
However, using PDL::Char doesn't store strings, it stores each char in
a different part of the grid... which kills the nice two-dimensional
nature of a csv file. So I'm using the above code with
$t_pdl=pdl(@temp) and referencing strings from the "2d" perl array I'm
pushing @temp onto.
Besides the ugliness of using a PDL and an "array" of "arrays", using
perl's slurp function would probably be faster - any suggestions on
how to slurp into a PDL? I find myself wanting to thread over a perl
array =/
On an entirely separate note... is there a pgplot command to draw an
unfilled circle?
