[datatable-help] How to produce variations of a text?

[nachti]

@affableambler

Explicit loops (e.g. for) are inefficient and should not be used if it's
possible.
unlist(lapply(...)) is safer than sapply(...)

I posted the lapply version, because if the result should be used within a
data.table, the right handside (right from :=) should be a list.
