yes, indeed!
BTW: Learn something more by considering the slight
variation
Sys.info()[['nodename']]
which is what you typically really want (and which will be very
very slightly more efficient in typical use cases).

I have some common code that I run on several computers and
each has a database with a different server name - although
the content is identical.
I need to set thisServer depending on which machine the code
is running on...
something like...
if(pcname = pc1) thisServer = 'SERVER1' if(pcname = pc2)
thisServer = 'SERVER2'
conn- odbcDriverConnect(driver=SQL
Server;database=x;server=thisServer;)
...rest of code will now run OK.
I know I could set the DSN names the same and use...
conn- odbcConnect(commonDSNname)
but I was wondering if there was another way

Re: [R] computer name
This depends on your OS.
on Windows,
Sys.getenv('computername')
should work.
Sys.info()['nodename']
should work on all systems.

Re: [R] computer name
Not exactly R, but how about
pcname - system('uname -n',intern=T)
