Apply Function to Each Cell of Data Frame in R (2 Examples) | All Elements | BaseR vs. dplyr Package

R code of this video:

x2 = letters[5:1],
x3 = 7)

my_fun ＜- function(x) { # Create user-defined function
paste0("out_", x)
}

my_fun(data$x1[3]) # Apply function to one value

data_new1 ＜- data # Duplicate data frame
data_new1[] ＜- lapply(data_new1, my_fun) # Apply function to each element

library("dplyr")

data_new2 ＜- data %＞% # Apply function to each element
mutate_all(my_fun)
