This change is required to allow majority of European users easily write csv to a format that would automatically open a csv in a correct way in Excel.
Thanks! Unfortunately we cannot have a dplyr dependency in readr. You can get the same behavior with the following.
numeric_cols <- vapply(x, is.numeric, logical(1)) x[numeric_cols] <- lapply(x[numeric_cols], format, decimal.mark = ",")
Can you also add a note to NEWS.md with this change and mentioning your GitHub username. Thanks!
