[R] change values in a character vector

[Peter Alspach]

Tena koe Henri-Paul

Does the following do what you want?

testVector <-  LETTERS[1:3]
temp <- matrix(c(rep(c(NA, 'foo'), each=length(testVector)), testVector, rep(c(NA, 'bar', 'blah'), each=length(testVector))), ncol=6)
c(t(temp))

HTH ....
