Making a windows packages with zip

Either the latter or ask the Windows users to install the source package.

Installing a source package doesn't seem to help:

install.packages("classifly", repos="http://ggobi.org/r/", type="source")

Warning message:
installation of package 'classifly' had non-zero exit status in:
install.packages("classifly", repos = "http://ggobi.org/r/",

(Unfortunately I don't have access to a windows machine at present -
this is what a user reported)
