setDreamerr_dev.mode {dreamerr}

Sets the developer mode to help form check_arg calls

Description

Turns on/off a full fledged checking of calls to check_arg. If on, it enables the developer mode which checks extensively calls to check_arg, allowing to find any problem. If a problem is found, it is pinpointed and the associated help is referred to.

Usage

setDreamerr_dev.mode(dev.mode = FALSE)

Arguments

dev.mode

A logical, default is FALSE.

Details

Since this mode ensures a detailed cheking of all check_arg calls, it is thus a strain on performance and should be always turned off otherwise needed.

Examples

# If you're new to check_arg, given the many types available,
# it's very common to make mistakes when creating check_arg calls.
# The developer mode ensures that any problematic call is spotted
# and the problem is clearly stated
#
# Note that since this mode ensures a detailed cheking of the call
# it is thus a strain on performance and should be always turned off
# otherwise needed.
#

# Setting the developer mode on:
setDreamerr_dev.mode(TRUE)

# Creating some 'wrong' calls => the problem is pinpointed

test = function(x) check_arg(x, "integer scalar", "numeric vector")
try(test())

test = function(...) check_arg("numeric vector", ...)
try(test())

test = function(x) check_arg(x$a, "numeric vector")
try(test())

test = function(x) check_arg(x, "numeric vector integer")
try(test())

test = function(x) check_arg(x, "vector len(,)")
try(test())

# etc...

# Setting the developer mode off:
setDreamerr_dev.mode(FALSE)
