Set to Single Threading

This function sets the threads used by {data.table} to 1 in the parent function and then restores the initial {data.table} threads when the function exits. This is primarily used as an internal function inside of other functions and will generally not be used on its own.

Usage

set_dt_single_thread()

Value

an environment in the parent frame named "dt_settings"

Examples

# \donttest{
data.table::setDTthreads(2)
test_function <- function() {
  set_dt_single_thread()

  print(data.table::getDTthreads())
}
test_function()
#> [1] 1
data.table::getDTthreads()
#> [1] 2
# }
