[R] Rounding and printing
Hello, I am trying to print a table with numbers all rounded to the same number of digits (one after the decimal), but R seems to want to not print .0 for integers. I can go in and fix it one number at a time, but I'd like to understand the principle. Here's an example of the code. The problem is the 13th element, 21 or 21.0: nvb_deaths - round(ss[,10]/100,digits=1) nvb_deaths [1] 56.5 1.6 0.2 3.9 0.1 2.2 0.2 2.6 1.5 4.1 1.1 6.1 21.0 nvb_dths - paste(nvb_deaths, (,round(100*nvb_deaths/nvb_deaths[1],digits=1),%),sep=) nvb_dths [1] 56.5 (100%) 1.6 (2.8%) 0.2 (0.4%) 3.9 (6.9%) 0.1 (0.2%) 2.2 (3.9%) [7] 0.2 (0.4%) 2.6 (4.6%) 1.5 (2.7%) 4.1 (7.3%) 1.1 (1.9%) 6.1 (10.8%) [13] 21 (37.2%) print(nvb_deaths,digits=1) [1] 56.5 1.6 0.2 3.9 0.1 2.2 0.2 2.6 1.5 4.1 1.1 6.1 21.0 paste(print(nvb_deaths,digits=1), (,round(100*nvb_deaths/nvb_deaths[1],digits=1),%),sep=) [1] 56.5 1.6 0.2 3.9 0.1 2.2 0.2 2.6 1.5 4.1 1.1 6.1 21.0 [1] 56.5 (100%) 1.6 (2.8%) 0.2 (0.4%) 3.9 (6.9%) 0.1 (0.2%) 2.2 (3.9%) [7] 0.2 (0.4%) 2.6 (4.6%) 1.5 (2.7%) 4.1 (7.3%) 1.1 (1.9%) 6.1 (10.8%) [13] 21 (37.2%) I'm running R v2.8.1 on Windows. Any help is much appreciated.

'round' only rounds numbers; it doesn't format them. Use 'formatC' instead. Example: x=c(1.234, 20.31, 25, 0.7) formatC(x, digits=1, format=f) [1] 1.2 20.3 25.0 0.7 'prettyNum' may also be useful. -- Karl Ove Hufthammer __ 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.
