Hi, I think what you did is correct. The row name 'comp168081_c2_seq1' is not in the filter data frame. Neither is the row as the following small example shows. Actually the dim(datawithoutVF) 171417 12 is different from dim(data) 171471 12. Or 171417 is not the same as 171471 although they have the same digits in different order in the last three digits.
Here I use your data renamed as rHelpData and want to get rid of the first three rows with row names stored in remove. Then I use the statement partData <- rHelpData[!rownames(rHelpData) %in% remove,] to store the result in partData. Then the content of partData shows the first three rows are filtered out. Hope this helps! > rHelpData apo1_LO apo2_LO apo3_LO apo4_LO lux1_LO lux2_LO lux3_LO lux4_LO WT1_LO WT2_LO WT3_LO WT4_LO comp230955_c0 0.00 8.05 8.15 32.91 0.00 38.41 0.00 17.45 16.59 0.00 0.00 0.00 comp135535_c0_seq1 1.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 1.00 1.00 0.00 comp222610_c5_seq4 4.96 8.21 1.84 5.57 14.59 6.54 6.51 3.78 5.43 11.87 6.01 1.99 comp227842_c8_seq3 93.53 131.08 79.54 198.85 166.32 108.80 43.79 125.63 45.37 34.13 103.42 67.90 comp230019_c3_seq1 141.97 355.04 142.11 71.02 497.84 424.01 212.69 142.03 70.95 70.54 70.93 142.23 comp215198_c1_seq3 18.27 28.28 10.52 0.00 64.35 0.00 0.00 21.05 17.74 0.00 19.66 0.00 > remove <- c("comp230955_c0","comp135535_c0_seq1","comp222610_c5_seq4") > partData <- rHelpData[!rownames(rHelpData) %in% remove,] > partData apo1_LO apo2_LO apo3_LO apo4_LO lux1_LO lux2_LO lux3_LO lux4_LO WT1_LO WT2_LO WT3_LO WT4_LO comp227842_c8_seq3 93.53 131.08 79.54 198.85 166.32 108.80 43.79 125.63 45.37 34.13 103.42 67.90 comp230019_c3_seq1 141.97 355.04 142.11 71.02 497.84 424.01 212.69 142.03 70.95 70.54 70.93 142.23 comp215198_c1_seq3 18.27 28.28 10.52 0.00 64.35 0.00 0.00 21.05 17.74 0.00 19.66 0.00 -- View this message in context: http://r.789695.n4.nabble.com/remove-rows-by-a-list-of-rownames-tp4702427p4702431.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
