Dear Mr. Ripley,
snowfall 1.7 is finished, and is now working on Windows as intended -
sorry for my oversight of that error. The given example now runs (as a
sidenote: snow does not have to loaded explicitely, snowfall will do that).
Also the NWS startup is fixed now (thanks to M. Schmidtberger for a
small patch) and an error in sfSapply is fixed.
Otherwise minor things were corrected or added.
I uploaded the package to CRAN yesterday and beside it is downloadable
from our site http://www.imbi.uni-freiburg.de/parallel
Greetings, Jochen Knaus

Dear all,
I am trying to execute the simple example in snowfall
http://cran.r-project.org/web/packages/snowfall/vignettes/snowfall.pdf
...
require(snow)
require(snowfall)
sfInit( parallel=TRUE, cpus=2 )
sfLapply( 1:10, exp )
sfStop()
I have installed the snow and snowfall packages in R on a machine with
windows xp, however, after running the "sfInit( parallel=TRUE, cpus=2 )"
line I get an error ...
Error in system("whoami", intern = TRUE, ignore.stderr = TRUE) :
whoami not found
Error in paste(sep = "_", "XXXXXXXXR", uname, format(Sys.time(),
"%H%M%S_%m%d%y")) :
object "uname" not found
I am the only (administrator) user of the computer. It has a dual core
processor, and is not networked.
I would be greatful if someone could tell me how to proceed.
Follow the posting guide (see the footer of this message) and talk to
the maintainer of 'snowfall'. Most likely it is not intended to be
used on Windows, but has not declared that. 'whoami' and 'uname' are
Unix programs, not Windows ones, but R's Sys.info() provides
equivalent information.
Kind regards
Chibisi
