I don't understand why you are trying to install a 2.5.x binary on R
2.6.0. Perhaps if you tried not to make things so hard for yourself and
just used the Packages menu to install RMySQL this might work: it does for
me and quite a few others.
Otherwise, you do need libMySQL.dll on the path or copied to the same
directory as RMySQL.dll to be sure that is not the issue. I suspect it is
rather an R version mismatch.

Dear list members --
I have problems in loading the pre-compiled library RMySQL_0.5-7 taken
here (http://stat.bell-labs.com/RS-DBI/download/index.html) or
RMySQL_0.6-0 taken here
(http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.5/) on R 2.6.0
under Windows XP. I am using the MySQL features of EasyPHP1-8 (but the
problem is not (for the moment) in connecting with a database but just
in loading the package)
I have seen all the previous posts explaining to copy the libMySQL.dll &
RMySQL.dll of the RMySQL library in the Windows/System32 folder or to
change the path variable in the Environment Variables of the system but
nothing helps.
I do wish people would not write things like that. Give URLs of what you
have read, since
- very often it is not 'all'.
- sometimes it is misread.
- some of the self-appointed experts are founts of misinformation (as
apparently here), so we need to know the credentials.
I still have the following message (I am sorry but, unfortunately, it is
in French; with my translation):
You can always start R in English (see the rw-FAQ) to quote English
messages. I would have expected there to be a message box as well (at
least under XP) saying what the missing procedure was (and that would be
in French, no doubt).
Error in dyn.load(file, ...) :
impossible de charger la bibliothèque partagée (="impossible to charge
the shared library")
'C:/PROGRA~1/R/R-26~1.0/library/RMySQL/libs/RMySQL.dll':
LoadLibrary failure: La procédure spécifiée est introuvable (="the
specified procedure cannot be found").
Erreur : le chargement du package / espace de noms a échoué pour
'RMySQL' (="loading package/space of names failed for")
I have just changed my computer and was previously on R 2.4, where I did
not have any problems in installing and loading pre-compiled versions
RMySQL.
Any help will be welcome.
