Dear all, I would appreciate a suggestion on the following : I am working with a data.frame (below) :
EXP CT row_names col_names 1 test -5 B4:B5:B6 B1:B2:B3 2 test -2 B7:B8:B9 B1:B2:B3 3 test -2 D4:D5:D6 H4:H5:H6 4 test -2 D10:D11:D12 F10:F11:F12 5 test -2 D10:D11:D12 H1:H2:H3 6 test -2 E10:E11:E12 G7:G8:G9 7 test -4 A1:A2:A3 D1:D2:D3 8 test -4 B10:B11:B12 B1:B2:B3 what would be the easiest way to consider UNIQUE elements in the ROW_NAMES or the UNIQUE elements in the COL_NAMES and : print how many times these UNIQUE ELEMENTS associate with the numbers -5, -2, or -4 (these numbers are on the column names CT) .. thanks, bogdan [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
