Destructive str(...)?
...range behavior of the str function - it seems to
modify the object that is displayed. Probably I'm using something
unsupported (objects consisting just of an external reference), but
still I'm curious as of why this happens. I create (in C code)
EXTPTRSXP and associate a class to it via SET_CLASS. Such objects works
fine until it's passed to str as the following output demonstrates:
> c<-.MCall("RController","getRController")
> c
[1] "<RController: 0x3be5d0>"

Dependencies of Imports not attached?

Error in getCurlHandle(cookiefile = cookie_path, .defaults = list()) :
could not find function "getClass"
As far as I can tell the error occurs when getCurlHandle .Calls a C
function which then calls SET_CLASS, which (I guess) requires
methods::setClass to be in the search path.
Now 'httr' Imports 'RCurl' which Depends on 'methods'. So I think
`library(httr)` should end up attaching 'methods' to the search path, but
it seems 'methods' is just imported to RCurl'...
