Introduction

Functional programming can lead to cleaner, more maintainable code. Learn how to effectively use functional programming techniques in R.

Map Functions with purrr

R

library(purrr)

# List of data frames
data_list <- list(
  df1 = data.frame(x = 1:3),
  df2 = data.frame(x = 4:6)
)

# Apply function to each element
result <- map_df(data_list, ~ {
  mutate(.x, squared = x^2)
}, .id = "source")
