I have a several "hash of a hashes" that look like this (sorry if my formating is a little off):

Human => { # HoH for human
1 => [1,32,54,67] # numbers in [ ] is a string delimited by commas not separate hash values
2 => [14,52,74,87]
5 => [33,44,64,107]
}
Chimp => { # HoH for Chimp
1 => [1,32,67]
2 => [14,74,87]
5 => [33,44]
}


Note: The numbers in between the [ ] is a STRING delimited by commas and NOT separate hash values. I already have a working script that appends these numbers to the appropriate hash separated by a comma or newline like this:
$class{$position} .= "$pos" . " ,"; #to get: 5 => [33,44,64,107]


And I am having trouble trying to compare data. I want to compare each number (i.e. 1, 2, & 5) and its data with e the same number in the other species. For example, I would like to print out a table (see below) that compares the data between the group "1" in each species.

Alleles for set: 1
Allele: 1       32      54      67
Human   1       1       1       1               # 1 = present
Chimp   1       1       0       1               # 0 = absent

And so on for 2 and 5.

I can most likely do the print formating for the table myself so I do not need help with that. I just need help with being able to compare the data within each Hash of a Hash (HoH). I do not know if I should read this data into yet another Hash (which would be very busy) or an array somehow? I have been trying to figure this out all week to no avail.

Any ideas or suggestions?
