plm 2.4-0

Speed up:

Significant speed improvement (optional, for the time being): A significant speed-up of the package is available by a newly introduced option called plm.fast such that panel model estimations and others run faster. Set option ‘plm.fast’ to ‘TRUE’ by options("plm.fast" = TRUE) for speed up, switch off by options("plm.fast" = FALSE) (switched off speed up is current default). To have it always switched on, put options("plm.fast" = TRUE) in your .Rprofile file. See documentation ?plm.fast for more information and a benchmarked example.

Technically, the speed gains are achieved by weaving in the fast data transformation functions provided in Sebastian Krantz’ package ‘collapse’, which needs to be installed (‘Suggests’ dependency).

Basic functions benefiting from speed-up are currently (used heavily in, e.g., plm()): Between, between, Sum, Within.
