[R] Sys.getenv

[Christian Hoffmann]

I am running R-1.3.0 on Solaris 8:

Under Solaris I do
setenv dendro_us hoffmann

echo $dendro_us gives back:
hoffmann

which is correct.

When in R I do:

Sys.getenv("dendro_us")  I get
dendro_us 
       "" 

which is NOT correct:

Inverse effect (taken from help of Sys.getenv)
Under R:
print(Sys.putenv("R_TEST"="testit", ABC=123))
[1] TRUE TRUE
Sys.getenv("R_TEST")   gives back:
  R_TEST 
"testit" 
which seems correct.

When in Solaris I do:
echo $R_TEST
R_TEST: Undefined variable.

which is NOT correct:

Third type of behaviour:
echo $HOME
/home/woodstock/hoffmann
and
Sys.getenv("HOME")
                      HOME 
"/home/woodstock/hoffmann" 

which are both correct.

QUESTION:
Are there two versions of the environment around? Or what am I missing?

>uname -a
SunOS fluke 5.7 Generic_106541-12 sun4d sparc SUNW,SPARCserver-1000

Thanks for help.
