I've loaded formula.tools in R. I now want to unload it, but when I run detach('package:formula.tools', unload = T) this package still affects the as.character function. See below for example.
Can anyone advise how to unload formula.tools such that it doesnt affect as.character?
# Behaviour of applying as.character to a formula before loading formula tools
as.character(formula(y ~ x)) #"~" "y" "x"
# Behaviour after loading formula tools
library(formula.tools)
as.character(formula(y ~ x)) #"y ~ x"
# Detaching formula tools doesnt change the behaviour
detach('package:formula.tools', unload = T)
as.character(formula(y ~ x)) #still "y ~ x"
