r mutate_each function is deprecated
问题 I use the function mutate_each from the tidyverse package and I get a message this function is deprecated. I would like to use the other functions that are not deprecated to change field types. Below is a reproducible example of how I currently employ mutate_each. library(tidyverse) set.seed(123) df <- data.frame(FirstName = sample(LETTERS[1:2],size=3, replace=TRUE), LastName = sample(LETTERS[3:6],size=3, replace=TRUE), StartDate = c("1/31/2000","2/1/2000","3/1/2000"), EndDate = c("1/31/2010"
