When trying to perform polychoric analysis on items from a questionnaire, I get the message "could not find function "polyc", even with the "psych" and "polycor" packages. Is there any way to solve this inconvenience? My gratitude in advance.

    Without any code it is hard to help you. What might be happening is that there is conflict, did you try psych::polychoric? – Henry Cyranka Dec 15 '18 at 16:56

    There is no `polyc` function in either of those packages. Do you mean `polychor` function from the `polycor` package? – mickey Dec 15 '18 at 17:03

Please try this:

install.packages("sos")
require("sos")
findFn("polyc")
