Some types of variables, such as logicals, trigger an update; when they do, predict.coxph cannot find the updated data set:

pbc$Male <- pbc$sex == 'm'
fit <- coxph(Surv(time, status!=0) ~ Male, pbc)
visreg(fit, 'Male')

tiggers an error because model.frame cannot find the reformatted, internal version of the data set created by visreg.
