Hi I'm working on installing R and Rcmdr on a Mac running Leopard. I've had it running in the past and had to reinstall 11X iwhen putting some notes together for students. To get screen shots I reinstalled 11X without unstalling it first. Having loaded the additional packages with Rcmdr, when I try to open Rcmdr I now get the following error messages: Error: .onload failed in 'loadNamespace' for 'Rcmdr' Error: package/namespace load failed for Rcmdr'' _X11TransSocketINTETConnect() can't get address for /tmp/launch- vCmK4L/:6000: nodename nor servname provided, or not know The last line X11 etc appears in red text. Any suggestion help would be grateful. Cheers, Alan.
