defaults in R: packages, .Rhistory

# 
With the current version (rw1070), every time I start R it loads a whole
bunch of packages, many of which I do not need in a typical session:
[1] ".GlobalEnv"      "package:methods" "package:ctest"   "package:mva"
[5] "package:modreg"  "package:nls"     "package:ts"      "Autoloads"
[9] "package:base"

Loading all these packages makes R slow to start up, and I presume it
uses up memory too.

Is there a reason that all these packages load automatically? Is
there some way to stop this from happening, by changing some default?

A separate question also related to defaults:

Is there a way to get R to refrain from truncating the .Rhistory file
(removing the earliest saved commands), so that .Rhistory might serve
as a permanent record of every command issued?

Thanks for any info

You can modify your sitewide Rprofile file (which for me is in 
C:\Program Files\R\rw1070\etc) and insert the line:

options(defaultPackages = character())

This should start R with no additional packages.  More information like 
this can be found in ?Startup.

Please use a parseable subject line, or two separate messages for two 
unrelated Qs.

Not much memory, and it is only methods which adds appreciable slowness.

            

      
      
      
    

        
Yes.  (You didn't ask what it was.)

            

      
      
      
    

        
Yes, and that is in the CHANGES file: please read it.

            

      
      
      
    

        
Not in RGui, *but* you can change the buffer size in the Rconsole file
or the Preferences.

Or you can set the environment variable R_HISTSIZE
