Dear All,

I am analyzing the miRNA data set in which I have 817 unique probes for each
they have 20  features each . I have to group the similar features and take
the median across them so that I have a data with no repeats to perform
invariant analysis .

My data looks something  similar format

probename  sample1 sample2 sample3
A                 2.3          2.4        2.5
A                 8.9          3.6        7.9
A                 4.7           4.4       2.2
C                 2.2           2.1       2.3
C                 1.3           1.3       2.9
B                 2.2            2.1      2.7
B                 2.2            2.1      2.8

I have to group the probename  elements and and get median across them.
Please help with this so that I can get complete my analysis .
