Dear all,
Is there *any* reason explaining what I describe below?
I have the following line
myfun(x)
If I type them directly in R (or copy/past), it works..
However if I type in R 2.6.1
> source("code.R") ##code.R includes the above line
Error in inherits(x, "data.frame") : object "d" not found
namely myfun() does not work correctly.
In particular the non-working line inside myfun() is
update(eval(x$call$obj), data=d) #d is created in myfun()
My question is: why the problem occurs just via source()ing???
many thanks,
vito
