What to you plan to do with this output file?

write.csv is for matrices, dataframes, and objects which can be  
coerced to dataframes. The result of a regression function would  
typically be a list that was way too irregular to be so coerced. You  
can see the organization f your "test" object with:

str(test)

Again. What is your goal?

Perhaps:

?dump
?dput
