Translate RDINA object into GDINA object
Description
This function translates an object of class RDINA to an object of class GDINA, so that the estimated R-DINA object is compatible with most of the functions in the GDINA package (Ma & de la Torre, 2020), including model fit, item fit, and Q-matrix validation.
Usage
RDINA2GDINA(fit)
Arguments
fit
An object of class RDINA.
Value
RDINA2GDINA returns an object of class GDINA. See the GDINA package for more information.

Examples
library(GDINA)
dat <- sim30DINA$simdat
Q <- sim30DINA$simQ
fit1 <- RDINA(dat, Q)
fit2 <- RDINA2GDINA(fit1)
modelfit(fit2) # Model fit evaluation
itemfit(fit2) # Item fit evaluation
