I have a data frame that has columns ranging from start_1 to start_32. I'd like to rename all of them to m1 to m32. So far I have done this using the following code:

df %>% rename(m1 = start_1, m2 = start_2, ... m32 = start_32)

I may need to do this a few more times for other variables and I am looking for more condensed way of achieving the same goal. Thanks!

You can use names:

names(df) <- gsub("^start_", "m", names(df))

or, in dplyr, with rename_with:

library(dplyr) rename_with(df, ~ gsub("start_", "m", .x), starts_with("start_")) rename_with(df, ~ gsub("^start_", "m", .x))
