High and low objects using R's car library

Question

I'm trying to add a column which reads my dataframe's column and outputs a 1 if the element is bigger than a certain number (and a zero if the condition isn't met). However, this code doesn't seem to work: df is an existing dataframe.

df2 <- data.frame(df2, C=Recode(df$numbers, "hi:200=1; else=0")) ##C = numbers > 200 = 1

I'm using R's car library.

Answer 1

Does this achieve what you need?

df2 <- tibble(numbers = c(1, 200, 201))

df2$recoded <- ifelse(df2$numbers > 200, 1, 0)

df2

# # A tibble: 3 x 2
# numbers recoded
# <dbl>   <dbl>
#   1       1       0
#   2     200       0
#   3     201       1
