(library(tcltk); tcl("info", "tclversion") will tell you which one is really loaded.) Google suggests that in earlier versions, there was an add-on called "TclX" that defined min and max functions (among other things, I presume). If it is in RH5.6, I would guess that you could load it with tclRequire("TclX") (or however it might be capiTaLized) before trying to do anything with sqldf().

Did you try the tclRequire() bit? These things are like R packages, it's not enough to install them; you also need to load them into the running Tcl interpreter.
