Replacement for “rename” in dplyr

Question

I like plyr\'s renaming function rename. I have recently started using dplyr, and was wondering if there is an easy way to rename variables using a function fr

While not exactly renaming, dplyr::select_all() can be used to reformat column names. This example replaces spaces and periods with an underscore and converts everything to lower case:

iris %>%  
  select_all(~gsub("\\s+|\\.", "_", .)) %>% 
  select_all(tolower) %>% 
  head(2)
  sepal_length sepal_width petal_length petal_width species
1          5.1         3.5          1.4         0.2  setosa
2          4.9         3.0          1.4         0.2  setosa
