Helpers to develop easier to understand code.

Source: R/helpers.R

A set of lightweight helpers that are often not strictly necessary, but they make code easier to read.

user(username = NULL)

machine(machinename = NULL)

node(machinename = NULL)

Arguments

username

A character string of a username.

machinename

A character string, which will be used as a partial match via grep, so the entire machine name is not necessary. A user can use regex if needed, e.g., "^machine1" will match "machine15" and "machine12", but not "thisIs_machine1".

Value

if username is non-NULL, returns a logical indicating whether the current user matches the supplied username. Otherwise returns a character string with the value of the current user.

machine returns a logical indicating whether the current machine name Sys.info()[["nodename"]] is matched by machinename.

Details

node is an alias for machine
