In some languages there is a function gensym() which returns a new unique name (in the current environment). This is quite helpful when one has to do temporary assignments. I could not find such a function in R. Is there one? -- Erich Neuwirth, Computer Supported Didactics Working Group Visit our SunSITE at http://sunsite.univie.ac.at Phone: +43-1-4277-38624 Fax: +43-1-4277-9386

hist(rbinom(1000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,300)) gives a histogram with "touching bars" hist(rbinom(100000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,30000)) gives a histogram with space between the bars. is there a way to control the space betweent he bars easily? -- Erich Neuwirth, Computer Supported Didactics Working Group Visit our SunSITE at http://sunsite.univie.ac.at

typeof applied to a factor always seems to return "integer", independently of the type of the levels. This has a strange side effect. When a variable is "imported" into a data frame, its type changes. character variables automatically are converted to factors when imported into data frames. Here is an example: > v1<-1:3 >

i installed r for window 1.2.1 and suddenly rcmd build does not work any more.

It would be convenient to have something like Rgui runfist="myfunction()" in Windows. The reason: AFAIK Rgui does not accept piped input (RGui < myfile.R does not seem to work). A solution could be to put a few fuctions in Rprofile and then give the name for one of these functions to be executed at startup as a command line parameter to Rgui. Can something like this be done? --

we still do not have dynamic graphics in R natively. i just found out about a widget library called fltk info is at www.fltk.org it has all the stuff r currently can do only through tcl/tk or (as i do it) excel: sliders, knobs, spinners and so on. it is multiplatform, there are production versions for unixen and windows, and there is a beta for macs. this could be a way of getting some of
