Splitting a string on the first space

by

The regular expression rexp matches the word at the start of the string, an optional space, then the rest of the string. The parenthesis are subexpressions accessed as backreferences \\1 and \\2.

rexp <- "^(\\w+)\\s?(.*)$"
y <- data.frame(MANUF=sub(rexp,"\\1",x), MAKE=sub(rexp,"\\2",x))
tail(y)
#       MANUF      MAKE
# 27  Porsche     914-2
# 28    Lotus    Europa
# 29     Ford Pantera L
# 30  Ferrari      Dino
# 31 Maserati      Bora
# 32    Volvo      142E
