Thus, when cut() gets to the 9th element in x, the value is undefined. > cut (x, seq(0, max(x) + 1, by = 1), label=FALSE) [1] 1322 1175 1155 1149 1295 1173 1289 1197 1356 1129 or > cut (x, seq(0, ceiling(max(x)), by = 1), label=FALSE) [1] 1322 1175 1155 1149 1295 1173 1289 1197 1356 1129 Both of the above approaches will increment the sequence 0:max(x) to 1356: > range(seq(0, max(x) + 1, by = 1)) [1] 0 1356 > range(seq(0, ceiling(max(x)), by = 1)) [1] 0 1356 Regards, Marc Schwartz ______________________________________________ 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.
