Examples

dummy <- data.frame(
  a = sample(1:4, 10, replace = TRUE),
  b = sample(1:4, 10, replace = TRUE),
  c = sample(1:4, 10, replace = TRUE)
)

rename_variables(dummy, a = "first.col", c = "3rd.col")

# using quasi-quotation
library(rlang)
v1 <- "first.col"
v2 <- "3rd.col"
rename_variables(dummy, a = !!v1, c = !!v2)

x1 <- "a"
x2 <- "b"
rename_variables(dummy, !!x1 := !!v1, !!x2 := !!v2)

# using a named vector
new_names <- c(a = "first.col", c = "3rd.col")
rename_variables(dummy, new_names)
