You could use scan. Have a look at package gsubfn, where there is a demo,
that show additional features you are going to use
library(gsubfn)
demo(gsubfn-gries)
....
The example code is a bit overnested, but to better understand what is going
on, unwrap it:
So
tail(sort(table(unlist(strapply(Lines1, "\\w+", perl = TRUE)))))
is:
x1 = strapply(Lines1, "\\w+", perl = TRUE)
x1
x2 = ulist(x2)
x2
x3 = table(x2)
x3
x4 = sort(x3)
x4
tail(x4)
