I have a list of dataframe and many of the columns will need to be renamed. It will be optimal to setup a key that I can use to rename the dataframe. The variables in the dataframe may or may not exist. I have been looking if there is a function that already do this but have not been able to find anything. The following example shows what I am trying to do.
# This is a dummy list with dataframes that may contain common variables data_list <- list( dfx1 <- mtcars, dfx2 <- mtcars %>% rename(`mpg.1` = mpg, `cyl2` = cyl), dfx3 <- mtcars %>% rename(`mpg.11` = mpg), dfx4 <- mtcars %>% select(-mpg) ) # Setup a key; the key does not have to be in this format mykey <- list( mpg = c("mpg.1", "mpg.11"), cyl = c("cyl2") ) # Is there a function that I can use to rename based in this key lapply(x, fun, mykey)
