[R] [External] Re: how to replace values in a named vector

[Richard M. Heiberger]

I can't understand non-words with that many letters.  I think this is what you
are looking for:

> tmp <- c(A="a",B="b",C="c",D="d")
> names(tmp)
[1] "A" "B" "C" "D"
> tmp
  A   B   C   D
"a" "b" "c" "d"
> ## change values of B and C to "x" and "y"
> names(tmp) %in% c("B","C")
[1] FALSE  TRUE  TRUE FALSE
> tmp[names(tmp) %in% c("B","C")]
  B   C
"b" "c"
> tmp[names(tmp) %in% c("B","C")] <- c("x","y")
> tmp
  A   B   C   D
"a" "x" "y" "d"
>

If not, please ask the question again with simpler-appearing vectors and show
us what you would like the answer to be.
