Hi All I am trying to use the round function on some columns of a dataframe while leaving others unchanged. I wish to specify those columns to leave unchanged.
My attempt is below - here, I would like the column d3 to be left but columns d1, d2 and d4 to be rounded to 0 decimal places. I would welcome any suggestions for a nicer way of doing this. d1= rnorm(10,10) d2= rnorm(10,6) d3= rnorm(10,2) d4= rnorm(10,-4) d = data.frame(d1,d2,d3,d4) x= NULL for (i in 1:ncol(d)){ if (colnames(d)[i] =="d3"){x[i] = d[i] } else { x[i] = round(d[i])} out = do.call(cbind,x) } colnames(out) = colnames(d) Thanks and regards Pete -- View this message in context: http://r.789695.n4.nabble.com/Rounding-variables-in-a-data-frame-tp3218729p3218729.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.
