I would like to calculate the average of column 4 from my input files.
#OPEN UP THE FILE
open (MYFILE, '148-N-pvalue0.01_peaks.xls');
#READ THROUGH THE FILE
while (my $line = <MYFILE>)
@arr1 = split('\t',$line);
@length = @arr1;
$numbers = join(", ",@length);
#$avg = avg($length);
But the problem is the array. How do I get commas between the numbers? And at the end calculate the average from the array?
