Rory Winston RBS Global Banking & Markets Office: +44 20 7085 4476 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Aaron Robotham Sent: 11 December 2008 17:07 To: r-help@r-project.org Subject: [R] very long integers A quick question really: I have a database with extremely long integer IDs (eg 588848900971299297), which is too big for R to cope with internally (it appears to store as a double), and when I do any frequency tables erroneous results appear. Does anyone know of a package that extends internal storage up to LONG, or is the only solution to read it in as a character from the original data? In case anyone is curious, I didn't create the IDs, and in some form I must conserve all of the ID information for later use.
