According to the download.file manual the timeout of a connection can be set
using options(timeout=10). This seems to work as expected on windows, but on
linux the connection does not timeout. I reproduced the problem both 0on
R-2.13 on Ubuntu and on R-2.12.1 on CentOS, but not in Windows.
I am running Ubuntu 11.04 with the R binaries from CRAN:
R version 2.13.0 (2011-04-13)
Platform: i686-pc-linux-gnu (32-bit)

locale:
 [1] LC_CTYPE=en_US.UTF-8       LC_NUMERIC=C              
 [3] LC_TIME=en_US.UTF-8        LC_COLLATE=en_US.UTF-8    
 [5] LC_MONETARY=C              LC_MESSAGES=en_US.UTF-8   
 [7] LC_PAPER=en_US.UTF-8       LC_NAME=C                 
 [9] LC_ADDRESS=C               LC_TELEPHONE=C            
[11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C

?connections tells us:

"Note that this is a timeout for no response, not for the whole operation."

And indeed, it will take roughly 20 seconds rather than 60 - at least on 
the Linux machine I tried it on with R-2.13.1.

Best,
