R

A new version of R is now available:

  • Accumulating vectors in a loop is faster – Assigning to an element of a vector beyond the current length now over-allocates by a small fraction. The new vector is marked internally as growable, and the true length of the new vector is stored in the truelength field. This makes building up a vector result by assigning to the next element beyond the current length more efficient, though pre-allocating is still preferred. The implementation is subject to change and not intended to be used in packages at this time.

There’s a big list of changes, so check it out and think about upgrading.

And usually the discussion goes as following: ,,We have tried LIME […]
