...xample: library(maps) iowa<-map("region","iowa) x<-iowa$x y<-iowa$y There are NA's and duplicated coordinates. What would I need to do to use this in the spatstat owin command? owin(poly= ?)

..., then x[[4]] <- value will fail rather than producing an illegal data frame * round(a data frame with numeric and factor columns) rounds the numeric columns and leaves the factor columns unchanged, rather than failing.

Hi everyone! In a package I'm developing, I have created a custom function to get jackknife standard errors for the parameters of a gnm model (which is essentially the same as a glm model for this issue). I'd like to add support for bootstrap using package boot, but I couldn't find how to proceed. The problem is, my data is a table object. Thus, I don't have one individual per

Hi, Rui and Michael, thank you both for replying. Yeah, I'm not supposed to know about Chi-squared yet. So far, all of our work with hypothesis tests has involved creating the sample data, then resampling it to create a null distribution, and finally computing p-values. The prop.test() would work. obviously. I'll look into that. I didn't know about it. I'm really struck by the
