Replace out-of-range values with the nearest in-range value

Source: R/clamp.R
clamp.Rd

clamp sets values less than min(range) to min(range) and values greater than max(range) to max(range)

Usage

clamp(x, range = c(NA, NA))

Arguments

x

A numeric or date/POSIXct vector.

range

A numeric or date/POSIXct vector of length two to clamp x to.

  • If range[1] is NA (default), then min(x) will be used.

  • If range[2] is NA (default), then max(x) will be used.

Value

A numeric or date/POSIXct vector equal to x with:

  • values less than min(range) set to min(range)

  • values greater than max(range) set to max(range)

Examples

clamp(1:5, range = c(2, NA)) # 2, 2, 3, 4, 5
#> [1] 2 2 3 4 5
clamp(1:5, range = c(2, 4)) # 2, 2, 3, 4, 4
#> [1] 2 2 3 4 4
clamp(1:5, range = c(-1, 1)) # 1, 1, 1, 1, 1
#> [1] 1 1 1 1 1
