Replace given value in vector
Perhaps replace is what you are looking for:
> x = c(3, 2, 1, 0, 4, 0)> replace(x, x==0, 1)[1] 3 2 1 1 4 1Or, if you don't have x (any specific reason why not?):
replace(c(3, 2, 1, 0, 4, 0), c(3, 2, 1, 0, 4, 0)==0, 1)Many people are familiar with gsub, so you can also try either of the following:
as.numeric(gsub(0, 1, x))as.numeric(gsub(0, 1, c(3, 2, 1, 0, 4, 0)))Update
After reading the comments, perhaps with is an option:
with(data.frame(x = c(3, 2, 1, 0, 4, 0)), replace(x, x == 0, 1))
