Formatting numeric values in a data frame
Hi R users, I have a data frame that contains 10K obs and 200 variables where I am trying to format the numeric columns to look like the output table below (format to 2 decimal places) but I am having no luck.. Can someone tell me the best way to accomplist this? Thanks in advance for any help! str(ad.test) 'data.frame': 10,000 obs. of 200 variables: $ ID : Factor w/ .................. $ x1 : num 0.1123334 0.4778966.......... $ x2 : num 0.00002 0.00002.............. $ x3 : num 12.33338 9.44446............. ==================================================== Data.frame....
