I think that's a good example that peer review works.

We can mistake in any language
I just read this
[Correction Notice: An Erratum for this article was reported in
Vol 17(4) of Psychological Methods (see record 2012-33502-001). The R
code for arriving at adjusted p values for one of the methods is
incorrect. The specific changes that need to be made are provided in
It's still functioning peer review if a mistake is found after an
article has been published, or after a pull request has landed in
in the research areas that I know, the vast majority of researchers
use Windows, and everything that is not core task is point and click.
As long as Matlab, Stata and GAUSS, or whatever else, doesn't have
version control build in, VC won't be used by the majority of
researchers that I know. We didn't grow up when version control was
popular. And we don't have IT guys to manage it for us.
(There is the old fashioned version control of starting new
directories at crucial stages, or for specific conference talks and
(DVCS are only a few years old, and it will take a few more years for
diffusion to "non-programmers" to happen.)
Even after using git some time, I only find it usable because I can do
all the regular stuff with git gui (and for unusual stuff I can use
commandline and git gui at the same time).
(just in case I'm misunderstood:
I'm all in favor of best practices and unit and functional tests, but
I don't expect that researchers will adopt it (fast) if it goes
against their usual pattern of using tools.
example: If you teach a software carpentry course that uses Linux,
then I wouldn't be surprised if some users go back to their office and
the first thing they do is use Excel. :)
(I used a virtual Debian for one month.)
