Using SetNames in dplyr
SetNames allows a mutate function to design a formula and rename the new mutated column accordingly. It works perfectly well across vectors as well.
Another benefit is that setNames can then also be run to check the formula:
E.g. to create a % column for Variable:
Variable <- "FactorX"
DF %>%
mutate_(.dots =
setNames( paste0(Variable,"/sum(",Variable,", na.rm = TRUE))"), paste0(Variable, "Pct"))
)
