Rounding values in a dataframe in R -


this question has answer here:

i have dataframe values shown below

january  february  march 0.02345  0.03456   0.04567 0.05432  0.06543   0.07654

i need command round each of these values 3 decimal points. output should shown below

january  february  march 0.023    0.035     0.046 0.054    0.065     0.077

in case data frame contains non-numeric characters may willing make use of function jeromy anglim:

round_df <- function(x, digits) {     # round numeric variables     # x: data frame      # digits: number of digits round     numeric_columns <- sapply(x, mode) == 'numeric'     x[numeric_columns] <-  round(x[numeric_columns], digits)     x }  round_df(data, 3)

i think it's neat , quick approach handle rounding problem across heterogeneous data frames.
