Examples

# Convert variables in a data frame to numeric where possible
test_df <- data.frame(var_a = c(1, 2, 3, NA, 4, 5),
                      var_b = c(1, 2, "Hello", NA, 4, 5))

convert_df <- test_df |> convert_numeric(c("var_a", "var_b"))

# Convert variables in a data frame to factor
test_df <- data.frame(var_a = c(1, 2, 3, 4, 5),
                      var_b = c("e", "c", "a", "d", "b"))

convert_df <- test_df |> convert_factor("var_b")
