This is rather strange and I suspect is a Windows issue rather than an R
issue, but it does not

seem to be mentioned on the lists so I am logging it in case it gives
anyone else problems.

 

Running Vista Business Version 6.0.6002 Service Pack 2 Build 6002, with
the latest R 2.10.0 patched.

 

A normal 'R' gui process:

 

> p <- Sys.getenv("PATH")

> nchar(p)

PATH 

1199 

> sessionInfo()

R version 2.10.0 Patched (2009-11-23 r50548) 

i386-pc-mingw32 

 

locale:

[1] LC_COLLATE=English_United Kingdom.1252 

[2] LC_CTYPE=English_United Kingdom.1252   

[3] LC_MONETARY=English_United Kingdom.1252

[4] LC_NUMERIC=C                           

[5] LC_TIME=English_United Kingdom.1252    

 

attached base packages:

[1] stats     graphics  grDevices utils     datasets  methods   base


 

Running R gui as administrator, however, the same path variable is
truncated:

 

> p <- Sys.getenv("PATH")

> nchar(p)

PATH 

1024 

> sessionInfo()
