R help - Sep 2015 - Error in eval(expr, envir, enclos) : could not find function

hi all

I am getting this error "Error in eval(expr, envir, enclos) : could not
find function ?

do you have an idea what might cause this problem. 

thanks

Please provide a context for your question. See the posting guide referenced
below for instructions on providing commented, minimal, self-contained,
reproducible code. If you can show how to produce the error, someone can almost
certainly show you how to avoid it.

You left out the rest of the error message (the name of the function
it is looking for is key):
    > lm(Y ~ nosuchfuncion(X), data=data.frame(Y=1:10,X=log(1:10)))
    Error in eval(expr, envir, enclos) :
       could not find function "nosuchfuncion"
