Sorry, I'm not understanding what you are telling me.

My question was when *specifically* did you get the error that you
report. That is to say, after which command of the 20 that you showed
us did this error pop up:

>> Error in function (classes, fdef, mtable)  :
>>  unable to find an inherited method for function "exprs", for signature
>> "data.frame"
