Hi, Try this, set.seed(2) # reproducible d = matrix(sample(1:20,20), 4, 5) d d[ d[ ,2] == 18 , ] You may need to test with all.equal if your values are subject to rounding errors. HTH, baptiste 2009/11/16 frenchcr <frenchcr at btinternet.com>:
I have 20 columns of data, and in column 5 I have a value of 17600 but I dont know which row this value is in (i have over 300,000 rows). I'm trying to do 2 things: 1) I want to find out which row in column 5 has this number in it.
Using baptiste's setup: > which(d[, 2]==18) [1] 4
2) Then I want to print out that row with all the column headers so i can look at the other parameters in the row that are associated with this value. How do i do it? -- View this message in context: http://old.nabble.com/printing-a-single-row%2C-but-dont-know-which-row-to-print-tp26376647p26376647.html Sent from the R help mailing list archive at Nabble.com.
