This I cannot get my mind around...
My data:
SNP Genotype
1 CC
1 CT
1 TT
1 NN
It seems to me that I need a hash of hashes.
Inner hash:
$inner{ $Genotype }++ ;
Since the value of the out hash ( $outer{ $SNP } ) has to be a scalar, this
scalar has to be a reference to the inner hash, correct? If so, how do I
declare them?
my %outer ;
Or should it be a reference to an anonymous hash?
my $outer = +{} ;
So that my code might look like:
$outer -> { $SNP }{ $Genotype }++ ;
Any help or reference is appreciated. My text on hand are "Mastering Perl
for Bioinformatics", "Perl for C Programmers", and the Llama book.
Thank you,
Kevin
