setFixest_nthreads

Sets/gets the number of threads to use in fixest functions

Description

Sets/gets the default number of threads to used in fixest estimation functions. The default is the maximum number of threads minus two.

Usage

setFixest_nthreads(nthreads, save = FALSE)

getFixest_nthreads

Arguments

nthreads

The number of threads. Can be: a) an integer lower than, or equal to, the maximum number of threads; b) 0: meaning all available threads will be used; c) a number strictly between 0 and 1 which represents the fraction of all threads to use. If missing, the default is to use 50% of all threads.

save

Either a logical or equal to "reset". Default is FALSE. If TRUE then the value is set permanently at the project level, this means that if you restart R, you will still obtain the previously saved defaults. This is done by writing in the ".Renviron" file, located in the project's working directory, hence we must have write permission there for this to work. If equal to "reset", the default at the project level is erased.

Format

An object of class function of length 1.
