Error when using neEffdecomp ()

[MikelSubiza]

Hello,

I am fitting natural effects models with medflex and when I run the neEffdecomp() function I get the following error message:

Error in names(dat1) <- all.vars(formula) :
'names' attribute [5] must be the same length as the vector [3]

If I run summary(mymodel) I get the standard outcome table, so I do not know where can the problem be.

Thank you very much.

Hello again,

I solved it now. One of the covariates was an ordered factor, and, after turning it into a "standard" factor variable (via <- as.numeric () + <- as.factor (), I was able to obtain the decomposed natural effects.
