Re: [R] How to round only one df row how to keep 3rd sigdif if zero
Hi You need to distinguish between an object and printing an object on console. When you print an object you can use several options for formating. ?sprintf, ?formatC formatC(t(a), digits=1, format=f) [,1] [,2] [,3] count 1.0 2.0 3.0 rate 16.7 33.3 50.0 Also when you transpose a the result is not data frame but matrix. str(t(a)) num [1:2, 1:3] 1 16.7 2 33.3 3 50 - attr(*, dimnames)=List of 2 ..$ : chr [1:2] count rate ..$ : NULL str(a) 'data.frame': 3 obs. of 2 variables: $ count: num 1 2 3 $ rate : num 16.7 33.3 50 If you used google or other internet search options you would get plenty of results yourself. try formatting numbers R Cheers Petr -Original Message- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of bcrombie Sent: Thursday, June 18, 2015 3:09 PM To: r-help@r-project.org Subject: [R] How to round only one df row how to keep 3rd sigdif if zero # How do I round only one row of a dataframe? # After transposing a dataframe of counts rates, all values took on the most # of signif digits in the dataset (rates), but I want counts to remain only one digit. # Also, how can I keep 3 significant digits in R when the 3rd is a zero? count - c(1, 2, 3) rate - c(16.7, 33.3, 50.0) a - data.frame(count,rate) a # count rate # 1 1 16.7 # 2 2 33.3 # 3 3 50.0 a - t(a) a # [,1] [,2] [,3] # count 1.0 2.03 # rate 16.7 33.3 50 -- View this message in context: http://r.789695.n4.nabble.com/How-to- round-only-one-df-row-how-to-keep-3rd-sigdif-if-zero-tp4708819.html Sent from the R help mailing list archive at Nabble.com. __ 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.

Re: [R] How to round only one df row how to keep 3rd sigdif if zero
Thanks for taking the time to share your thoughts, PP. I always extensively google search before resorting to R forum. In my real dataset, not in the example I created for the forum, I had tried converting the matrix to a dataframe but it retained the unwanted format. And, these tables are being used in a report generated with the rtf package, so I have to get the format right for outside the console. Because of another unrelated issue, though, I had to use a different approach to creating the dataframe with counts/rates added, so the issue was circumvented.
