if you need it quickly, here is a hack. there may be better ways.
# some rubbish data
d = data.frame(x = replicate(10, paste(sample(c(letters, 0:9, " "), 10),
collapse="")))
patterns = paste("[", c("^", ""), "A-Za-z]| ", sep="")
for (i in 1:2) d[patterns[i]] = gsub(patterns[i], "", d$x)
tweak the regex patterns accordingly to your demand for whitespace etc.
rename the columns as you like.
