 Here is my code: library(tidyr) messy <- data.frame( name = c("Wilbur", "Petunia", "Gregory"), a = c(67, 80, 64), b = c(56, 90, 50) )  And I would like to use gather function with variable/function result. Borrowing from I tried: not_messy <-messy %>% gather_('drug', 'heartrate', paste0('a',''):paste0('b',''))  But it generated error: Error in paste0("a", ""):paste0("b", "") : NA/NaN argument In addition: Warning messages: 1: In lapply(.x, .f, ...) : NAs introduced by coercion 2: In lapply(.x, .f, ...) : NAs introduced by coercion  What am I missing?
