hi netters, i have a gene expression matrix where rows are genes and columns are conditions. The values are either "A"(absent) or "P"(present). There are 15 conditions in total. If a gene is absent in most of these conditions, say at least 13 out of the 15 values are "A", then I would like to remove this gene from the matrix. So finally I'll get a new matrix with only those genes that are present in at least 2 of the conditions. Could anyone give me a hint about how to write the code? Thanks a lot!
