Probably not, R is case sensitive and without loading an external 
package that instruction will give an error. Try

wilcox.test(x, y)


with *lower* case *w*.

By the way, why would you test the residuals of regression fits?
It doesn't make sense, especially if the models (algorithms) assume 
residuals with mean zero. I suggest you learn more about the techniques 
you are using to model your data before trying to test.


Hope this helps,
