An rvec with the same number of draws as condition.

• base R function ifelse() does not not work correctly if any of the inputs are rvecs.

• dplyr function if_else works correctly if arguments true, false or missing are rvecs, but not if argument condition is an rvec.

Examples

x <- rvec(list(c(1, 11),
               c(2, 5),
               c(22, 6)))

x > 10 ## rvec_lgl

## if_else_rvec needed when
## 'condition' is an rvec
if_else_rvec(x > 10, 10, x)

## dplyr::if_else works when
## 'true', 'false', or 'missing'
## (but not 'condition') are rvecs
library(dplyr)
if_else(c(TRUE, FALSE, TRUE), x, 100)
