The binomial function contains the following code fragment (R 1.0.1): if (any(linktemp == c("logit", "probit", "cloglog", "log"))) stats <- make.link(linktemp) else stop(paste(linktemp, "link not available for binomial", "family, available links are \"logit\", ", "\"probit\" and \"cloglog\"")) and from this it is unclear if "log" is an available link function or not.
