Is there an r function that will be able to identify the computer the code is running on? 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 -- View this message in context: http://r.789695.n4.nabble.com/computer-name-tp3593120p3593120.html Sent from the R help mailing list archive at Nabble.com.
