The scripts are in simple files installed with the package. So you need to go to the install directory and read them from there. A canonical way of finding it from within R is

.path.package("MASS")
dir(file.path(.path.package("MASS"),scripts)) file.show(file.path(.path.package("MASS"),"scripts","ch05.R"))

That being said, I couldn't off-hand spot anything ASH-like in the file. This might either be a difference between the R and S versions, or just that the remark in the figure caption does not spefically relate to ASH (haven't got the book at hand just now).
