Yes, this is fully reproducible with examples from ?allEffects. The
problem is that summary.efflist() does not return an object that R2HTML
could print(). Instead, it calls print() directly on all of the separate
effects in the list, and returns invisible(NULL).
You can fix this by making summary.efflist() return an object containing
the needed data, and creating a function to print this object as below.
Maybe John Fox will want to apply this kind of change to the package.
Regards
summary.efflist <- function (object, ...)
{
form <- object[[1]]$formula
attributes(form) <- NULL
ret <- list(formula=form,
eff=lapply(object, summary, ...))
class(ret) <- "summary.efflist"
ret
}
print.summary.efflist <- function(x, ...)
{
cat(" model: ")
print(x$formula)
for (effect in names(x$eff)) {
print(x$eff[[effect]], ...)
}
invisible(x)
}
