Hello everyone, I hope this reaches someone at all. It's my first bug report to the R-core, and, apparently, bugzilla is locked from new reports for now. I was using `methods::insertSource` to debug and successfully fix another package, until it suddenly stopped working. I figured out, that it is because I am using it on the same function multiple times within one session. It also produces warnings even during the first call, but somehow still works. Below I provide a reproducible e...

...eturning an environment object which is a snapshot of the code. From this environment, functions and methods can be inserted into the environment of the package in the current session. The insertion uses the trace() mechanism, so the original code can be restored. The one-step version is: insertSource("mySourceFile.R", package = "myPackage", functions = "foo") This is intended specially for those of us who own largish packages. (It proved useful in debugging itself, e.g.) You can use the other trace() mechanisms with it, with a little care, as well as debug() e...

...the formula class now displays the associated environment if it is not the global environment. ? A new facility has been added for inserting code into a package without re-installing it, to facilitate testing changes which can be selectively added and backed out. See ?insertSource. ? New function readRenviron to (re-)read files in the format of ~/.Renviron and Renviron.site. ? require() will now return FALSE (and not fail) if loading the package or one of its dependencies fails. ? aperm() now allows argument perm to be a character vector when...
