[Rd] problem loading packages (PR#559)

[rnassar@duke.edu]

Dear R team,

I had a strange problem that appeared suddenly, and which I'd like to
to mention in case it is of interest (although I suspect that I
may have unwittingly done something dumb: if so please accept my apology)

> library(ctest)      ## or any package other than "oz" that I tried
Error in as.character(table) : Object ".Dyn.libs" not found
> traceback()
[1] "as.character(table)"                "match(chname, 
.Dyn.libs)"          
[3] "library.dynam(\"ctest\", pkg, lib)" "firstlib(which.lib.loc, 
package)"  
[5] "library(ctest)"                    

I traced the problem to my .RData file, and specifically to ".AutoloadEnv"

> ls(all.names=TRUE)
 [1] ".AutoloadEnv"        ".GlobalEnv"          ".Library"           
 [4] ".Machine"            ".Platform"           ".PostScript.Options"
 [7] ".Provided"           ".Random.seed"        ".Traceback"         
[10] ".lib.loc"           

I removed the above, one at a time, and tried loading a library.  It
worked after I removed  ".AutoloadEnv".  I confirmed it by checking
that R works normally if I only remove ".AutoloadEnv".  I don't know
what could have caused the problem in the first place.  The contents
of ".AutoloadEnv" are shown below: 

> .AutoloadEnv
<environment: 0x40691ddc>
attr(,"name")
[1] "Autoloads"

> rm(".AutoloadEnv")
> library(gee)
> library(nlme)
Loading required package: nls 


Thank you very much.
