Hi.
How do I convert a one-dimensional array of characters to a character
vector? In the example below I am trying to get the result c("a","d"). The
function as.vector() returns the same one-dimensional array, and unlist()
returns something more complicated than I seek.
Yours truly,
Ronnen.
P.S. E-mailed CCs of posted replies appreciated.
