My message seemed to get a bit lost in that discussion so just to bring it back ...
Changing that to mod instead of r(mod) results in predicted=r.predict(*r(mod)*, type='response', ncomp = 10, newdata = accFAS ) gives the following error Traceback (most recent call last): File "C:\Documents and Settings\Administrator\Desktop\pls\pls.py", line 40, in <module> predicted=r.predict(mod, type='response', ncomp = 10, newdata = accFAS ) RPy_RException: Error in eval(predvars, data, env) : numeric 'envir' arg not of length one which is why I had thought it was r(mod) originally; or is this error telling me something else is wrong? What does "numeric 'envir' arg not of length one" refer to anyway?
