R Quick Tips

Convert R TRUE and FALSE values to 1 and 0, and vice versa

Here is a simple method to convert R TRUE and FALSE values to 1 and 0, and vice versa.

Here is my data frame.

df <- data.frame(
  Date  = as.POSIXct(c("2019-12-01", "2019-12-02", "2019-12-03", "2019-12-04", "2019-12-05", "2019-12-06", "2019-12-07", "2019-12-08", "2019-12-09", "2019-12-10")),
  Values1 = as.numeric(c("2", "8", "7", "10", "13", "9", "12", "14", "11", "8")),
  Values2 = as.numeric(c("1", "8", "9", "10", "13", "9", "17", "6", "11", "20")))

If I’m doing some calculation that gives me TRUE or FALSE then sometimes it is necessary to convert them to 1 and 0.

df$Same <- df$Values1 == df$Values2

The easiest way is by using a function as.integer.

df$SameInt <- as.integer(df$Same)

Convert R 1 and 0 values to TRUE and FALSE

Sometimes it’s another way around. Here you go.

df$SameLogic <- as.logical(df$SameInt)
