[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,

Here's the answer to my question that I came up with after working with all of your suggestions. It's not elegant by any means but gets the job done: MERGE_PViol.Detail.Per.Case <- read.csv("~/FOIA_FLSA/MERGE_PViol.Detail.Per.Case_for_rtf10.csv", stringsAsFactors=TRUE) # select only certain colum

AK, I decided to convert your “with” statement back to index-by-number, and I did look up the ?with help info, but I’m confused about my replacement code below. I got the wrong answer (R didn’t apply the function to my column 1 variable “A_CaseID”). What am I doing wrong? Do I nee

Arun, thanks for clearing that up. I was making assumptions about R that I shouldn’t have when it comes to column(variable) assignments. Hope everyone has a good Monday. BNC From: arun kirshna [via R] [mailto:ml-node+s789695n4671473...@n4.nabble.com] Sent: Friday, July 12, 2013 11:59 PM To:
