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.

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 >

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? --

1. This query belongs in r-help, not in r-devel 2. Pity about your shift key... 3. The function you need is deparse() rather than as.character(): > fff <- function(x) { + x*x + } > deparse(body(fff)) [1] "{" "x * x" "}" > 4. There is a reason why as.character works this way. It transforms to character from a more fundamental representation of

Using Thomas Baier's DCOM server I can do the following (in Windows 2000): I create a slider in Excel, and the sliders On_Change event triggers a call to R. This call redraws an R graph, and so I have animated R graphics controlled by Excel's slider. The problem is that Excel needs focus so i can grab the slider, and therefore it partially covers R's graph window. Is there a way to

i just used read.fwf (which calls perl) and i noticed something. i also have mat;lab installed on this machine, and matlab also installs a version of perl, but a different one. additionally, matlab puts its bin directory in the system path. so, if one does not canerully set the path, r will call the matlab verion of perl, and things won't work. if anybody is collection a list of pitfalls,
