If I have a series of values
set.seed(123)
x <- rnorm(100)
and a given range (a, b), e.g.
a <- -1; b <- 2
How could I move those values less than a to a and those greater than b to b?
The following basic method works but I’m searching a function or a one-liner command.
x[x < a] <- a
x[x > b] <- b
>Solution :
If we need a single line, use pmin/pmax
out <- pmin(pmax(x, a), b)
-checking
x[x < a] <- a
x[x > b] <- b
identical(out, x)
[1] TRUE
