Hmmm.... I think that this (parsing comma-delimited files) doesn't
get much mention in PDL sources because Perl is so good at it.
Something like:
$pdl = pdl( map { [ split /\,/ ] } @lines );
or, slightly less tersely:
@table = map { [split /\,/ ] } @lines;
$pdl = pdl(@table);
That, in turn, is equivalent to the more long-winded form:
@table = ();
for my $line(@lines) {
my @line = split /\,/, $line;
push(@table, [EMAIL PROTECTED]);
}
$pdl = pdl(@table);
Cheers,
Craig

Re:

As a newbie user, I can attest to the need- the POD is pretty good,
but
it's like a dictionary: you need to know what to look for in order to
find it!
I'd happily volunteer as a guinea pig for testing drafts on.
