Hi,
We're using stats4 for a logistic regression. The code is
chdreg.logit2 <- glm(chd ~ age + sex, family = binomial)
summary(chdreg.logit2)
oddsratios <- coef(chdreg.logit2)
exp(oddsratios)
# Calculate model predicted values
pred <- predict(chdreg.logit2,type="response")
The glm part runs fine, and up to now so has the predict function.
However, now we're getting the following error
Error in function (classes, fdef, mtable) :
unable to find an inherited method for function "predict", for
signature "glm"
Any thoughts about why this seems to now be appearing.
Thanks in advance.
Just a guess, but perhaps you've loaded some other package which
redefines predict() in an incompatible way?
