Several libraries won't load with (PR#6927)

Thank you both.

1. It looks like part of the problem is indeed that the packages in the
patched version for Windows aren't coordinated with the libraries.

rw1090
library(MASS)  ## works

rw1090pat
library(MASS)  ## doesn't work
library(MASS, lib.loc="c:/progra~1/R/rw1090/library")  ## works


2. This doesn't explain why the freshly downloaded Hmisc and multcomp
packages didn't load.  I now think that is due to a documentation
problem.  I am using Windows.  All the documentation for installing
packages is Unix-centric.  Your emails were also Unix-centric.

After wandering through documentation I initially unzipped the
downloaded files, for example,
    Windows binary: Hmisc_2.0-9.zip
into the rw1090pat/library.  This unpacked correctly but did not load.

After your emails, I tried Rgui and found the "Packages/Install
package(s) from local zip files..." menu item.  I did this and now it
works.  The unzipped files in library/Hmisc/* are identical when I did
a manual unzip and when I did the menu installation.

Suggestion: please add a paragraph to the top of the Contributed Packages
page that says, "Windows users---including ESS Windows users---should install
the downloaded zip file with the Packages menu item from Rgui".

isn't the problem.  I have two Rgui and one iESS [R] running and all three
have loaded the Hmisc and multcomp packages.

Rich,

packages are coordinated! Note that *recommended* (not base!) packages 
are included in release versions only, hence you have to install them 
separately in patched/devel versions of R!
   install.packages("VR") should do the trick ...

            

      
      
      
    

        
No.

No. There is the R Installation and Administration manual (mentioning 
details on the Windows version),
?install.packages, ?INSTALL and there is the R for Windows FAQ (the 
latter two are for sure very Windows-centric).


 > Your emails were also Unix-centric.

No. What was Unix-centric in my e-mail, please? I am using Windows 
almost all the time ....

            

      
      
      
    

        
Unzipping should work as well, but maybe your files were still locked at 
that time?

            

      
      
      
    

        
In that case I guess you haven't detached and loaded the package again 
when you tried at first?
install.packages() hasn't much more side-effect (just updating some 
indexes which are NOT required to load the package).

            

      
      
      
    

        
Hmm. The first paragraph says:

Please type help(INSTALL) or help(install.packages) in R for information 
on how to install packages from this directory. The manual R 
Installation and Administration (also contained in the R base sources) 
explains the process in detail.

And these documents tell to use install.packages(). So no need to add 
anything from my point of view. There is also a Section 3.1 in the R for 
Windows FAQ....

            

      
      
      
    

        
Maybe, but after you have loaded the package, you cannot overwrite it, 
because the dll files are locked (yes, dlls are locked when in use under 
Windows). So Martin's analysis was correct.
Therefore you have to detach those packages you want to re-install or 
update (and also close all chm documentation - or even better close 
corresponding instances of R).
