Your call to glm() is not doing what you think it's doing. What you want to do is probably closer to glm.fit <- glm(living ~ day, data=fflies, family="binomial") Where ffiles$living has exactly two values, e.g., "alive" or "dead" or some other pair. After you do this, you want to examine glm.fit very carefully. Make sure you can interpret all of the output of summary(glm.fit). Until you do, there's no point in trying to plot. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
