Hi R-users, Can Maple function be exported to R? I have a jacobian matrix (4X4)?from maple in algebraic form which involve modified Bessel function of the first kind. I just wonder whether we can use algebraic form into R before the value of the parameters can be estimated. Thank you so much for your attention and help.

Hi the list, I used savePlot to export some eps graph but it seems that the graph file hold a bug. I include the graph.eps in a LaTeX file. Running latex is ok. But the dvi file contain some mistake, the graph overprint on some text and hide it. Then, when I try to convert it to another format, I get : Ignoring remaining special text following unkown PS operator: "SDict" Remainder

Hi r-users,   I try to draw histogram (in terms of probabilty) and superimpose with the gamma pdf. Using this code below I can get the plots BUT the y scale for the density is out of scale.  How do I change the y-axis scale to max 1?  Another thing, how I do draw smooth line rather that points?   Nota that my observed data is hume_pos and the fitted data is rgam1.   hist(hume_pos,prob=TRUE)

Plaintive squeak: Why the change? Some OS's and desktops use the extension, so forgetting it causes trouble. The new default filename keeps a filetype (as before) but the user now has to type a filetype twice (once as the type, once as extension) to get the same effect fo rtheir own filenames. And the extension isn't then checked for consistency with valid file types, so it can be

Dear All, I am looking for the best way to use graphs from R (like xyplot, curve ...) for a presentation with powerpoint.
