[R] snow::makeCluster on Windows hangs

[Jeffrey Flint]

The command which hangs:
I'm hoping there is a simple explanation, but I searched on-line and
nothing jumped out.

> cl <- makeCluster(type="SOCK",c("localhost"),manual=TRUE)
Manually start worker on localhost with
     C:/PROGRA~1/R/R-214~1.2/bin/Rscript.exe "C:/Program
Files/R/R-2.14.2/library/snow/RSOCKnode.R" MASTER=localhost PORT=11944
OUT=/dev/null SNOWLIB=C:/Program Files/R/R-2.14.2/library
[HANGS]
