base::deparse()
documentation page says:
Using
control = "all"
comes closest to makingdeparse()
an inverse ofparse()
. However, not all objects are deparse-able even with this option and a warning will be issued if the function recognizes that it is being asked to do the impossible.
Please provide an example of an object that is not deparse-able?
It appears that S7 objects are not deparsable. Borrowing the example from the vignette
library(S7)
dog <- new_class("dog", properties = list(
name = class_character,
age = class_numeric
))
lola <- dog(name = "Lola", age = 11)
deparse(lola)
# Error in deparse(lola) : 'S4SXP': should not happen - please report
My guess is that such an object should be deparsable so maybe future updates may change that. Interesting deparse(dog)
seems to work fine.
