Looks like mar is a class of mads, and is an output from mice package? glm requires input as dataframe, so it is failing to convert. – zx8754
mar is an output of ampute() in mice package – M.Salim
i have try to convert – M.Salim
mar<- as.data.frame(mar) ... but still i got the same error – M.Salim

If you want to use the amputed data (result of ampute) to fit a model you can extract this with

mar$amp

in your example

fit.mis<-glm(Probation ~ Times_UP+Library+Activity,family=binomial,mar$amp)
