Hi all, I was wondering if I might subscribe this list to gmane.org, so I (and everyone else) might view and search in with a newsreader? Also--is there any way to get it indexed by google, maybe along with the r-help list (or is it already but I haven't found it)? Thanks for your consideration W

Hi R-heplers, I would like to print various matrices, dataframes, tables, etc to files, preferably nicely formatted postscript for import into papers. Is there a way to do this? I know ?cat, ?writeLines, ?format, ?paste. But I am not sure of a good combination of these in order to get a nice looking table of information. Any ideas? I guess I want (almost) publication ready output, just

Hi R-helpers, Does anyone know of a good Tk (or other) script that allows somewhat intuitive viewing of all of the variables (especially complex lists) in a session? I would also like to delete, save to file, and rename them graphically. I would also like a lot of supplemental information like class, atrributes, names, modes, whatever else... Context: I am running simulations

Hi R-helpers Has anyone had any experience doing CGI or Servlets or using an httpd server in R? Context: we are interested in running dynamic demographic calculations on the internet (life tables, and such) in response to form submissions. I might do simple cgi to get started, but loading in data each time seems like it would be quite, quite slow. I have looked at Rserv, but I am most

Hi All, (I have a degree in math, but I am too embarassed to ask my colleagues, so here goes:) I would like to get a vector normal (orthogonal) to a plane formed by two other vectors. In matlab I do this: v1 = [.4, .6, .8]; v2 = [.9, .7, .2]; nn = cross(v1,v2) (gives ~[-.48, .65, -.24] if I do R> cross(v1, v2), I get .94. Huh? Thanks for all your help, again. W

Hi R-helpers, I have a data.frame with three columns (lots more reps though in each), like so: 'FOO' 'BAR' 'RESULT' 1 .01 75 1 .05 12 1.1 .01 100 1.1 .05 50 1.2 .01 75 1.2 .05 12 I am calling boxplot(RESULT ~ FOO:BAR, ...) This

Hi all, I dump the result of a long simulation, which I know has run to completion and returned a fairly complex list of lists of things. However, when I try to read it back in, I get the following error: > source ('../SIMULATIONS/run.1.R') Error in structure(list(do.extinction.runs, alpha = 1.8, delta.change = 0.005, : Object "do.extinction.runs" not found I think the

Hi R-developers I have noticed a strange little bug/feature: I often create pdf's of plots, then edit them in Adobe Illustrator. Generally this works great, but whenever I have text that is aligned vertically (along the y-axis usually), the text is written out as lots of individual objects. When the text is horizontal (x-axis, other stuff), it is all one object. I would prefer one object

Hi R-helpers I would like to plot some planes which are perpendicular to the x-y plane, such as x=y. Is there a way to do this in wireframe? I realize that I am not plotting a function of x, y since there are infinite number of z's that satisfy the above relation.... Hmm... Somewhat related, I would also like to plot a line in 3 d space... Finally, if you are feeling really brave, I

Hi all, Is there any documentation on running R like one would run a shell or Perl script, with out/input directed appropriately, environment variable access, and command switch processing? I looked some, and even remembered to check the FAQ, but couldn't find anything. Thanks W

Hi all, I have searched but to know avail. Is there a way to get a line number when a function crashes? I am doing an edit->source->run cycle. Feel free to cc me as I subscribe to the list in digest. Thanks W
