but upon re-starting R2.10.0 I learned that
chmhelp = TRUE is no longer supported: use help_type ="text"
I'm sure this was explained elsewhere but I missed it. Could someone explain
why the compiled html help is no longer supported?
Several reasons. The two that convinced me are:
- it is static-only. There's no possibility of dynamic pages, as the
other formats support.
- it requires tools that are not ours, and that we can't distribute.
There are also security concerns with the format.

Thanks.

If you set

you'll get HTML help with links in your default browser.

Thank you very much, this works. But I am very surprised that it is
not the
default. Having chosen html help during installation, I would have
expected
this to be active without having to change an option.
Yes, it should have been, but there was a bug in the installer, and the
preference indicated there was ignored. This is why it's useful to have
people doing testing during the beta test period: things like this are
easy to fix, but they need to be noticed first.
Duncan Murdoch
And let me add:
The whole statistics department has been on two pre-release versions
(beta and release-candidate) and nobody reported any error. The
installer problem has not been found because I installed from sources
anyway. This shows it makes sense to have more than just 400+ beta
testers. ;-)
Uwe
Two more comments: For those of us who have already installed the version
with this installer bug: If you do not want to change the option each time
you call R, it is easy to change it permanently in the file
R_HOME/etc/Rprofile.site (where R_HOME stands for the directory in which
your R is installed, e.g. c:\programs\r\r-2.10.0).
Regarding beta testing (yes, I admit, I usually leave that to others, and am
nevertheless looking for beta testers of my package RcmdrPlugin.DoE), maybe
it would be time for an experimental design that specifies characteristics
of beta testers to ensure some diversity there, perhaps package DoE.base or
FrF2 could help there (half-, but only half-jokingly) ;-)
