Dear experts,
I think this is a fairly simple question...
How can I count empty values in an array? This count
should not include zeros or non-empty values. Below
is my current script, but it isn't working properly.
I appreciate any assistance that you may provide.
Thank you,
David
#!perl -w
# Count missing values
while (my $line = <>) {
chomp ($line);
my ($probe_id,$expression) = split /\t/, $line, 2;
my @expression = split /\t/, $expression;
my $count = 0;
foreach my $value (@expression) {
if (!$value) {
$count += 1;
}
}
print "$count\n";
}
