Hello, I have an input file that contains multiple columns, but the column I'm concerned about looks like:
"TR" 5 0 4 1 0 2 0 To count all of the rows in the column I know how to do NROW(x$TR) which gives 7. However, I would also like to count only the number of rows with values >=1 (i.e. not 0). I've tried NROW(x$TR>=1) which did not give the intended output. Do any of you have any suggestions as to where I'm going wrong? -- View this message in context: http://r.789695.n4.nabble.com/Counting-rows-given-conditional-tp3718541p3718541.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list 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.
