I don't see why; rawToChar(, multiple=FALSE) is meant to be a map from an n-vector to a scalar. Why should there be an exception when n==0? Would you expect mean(numeric(0)) to return numeric(0)? > Same should then apply to charToRaw(), but right now we get: > > > x <- character(0) > > charToRaw(x) > Error in charToRaw(x) : argument must be a character vector of length 1 The error message says it all: charToRaw() maps a scalar to an n-vector. For vectors of length > 1, it uses the first element with a warning.
