Hi, I'm new to R and there is something I'm missing about how it uses memory. I'm doing a simple query (using RODBC package) and immediately set the data.frame to null close the connection/channel and explicitly call to the garbage collector (gc()) however when I look in the task monitor I see both "VM size" and ""Mem Usage" increased every time (for the RGui). I tried this on different configurations: windowxp64 / windowsxp and R version 2.4.1 and 2.5.1. What I'm doing wrong? Thanks, Yoni.
