Sets dreamerr argument checking functions on or off

Usage

setDreamerr_check(check = TRUE)

Arguments

check

Strict logical: either TRUE of FALSE. Default is TRUE.

Examples

# Let's create a small function that returns the argument
#  if it is a single character string, and throws an error
#  otherwise:

test = function(x){
  check_arg(x, "scalar character")
  x
}

# works:
test("hey")
# error:
try(test(55))

# Now we disable argument checking
setDreamerr_check(FALSE)
# works (although it shouldn't!):
test(55)

# re-setting argument checking on:
setDreamerr_check(TRUE)
