Jeez I dunno - it compiles perfectly and you guys get excited just because it doesn't work :-) I have to admit to being baffled about what happened (I'm SURE this was working not long ago), but here is a quick fix. The problem is in the function "GetCharInfo" in the file src/unix/PostScript.c. The fix is to change the statement if(nchar < 0) return 0; to if(nchar <

In the following titletxt <- substitute(paste(tx, tilde(y) == sqrt(y)), list(tx="Replace y by ")) I'd like to be able to replace e.g. sqrt(y) by a symbol or symbolic expression that has the effect of inserting sqrt(y) into the place that it occupies. This would allow me to put an arbitrary expression into that position. [One can use text() or mtext() etc. to place titletxt

Paul Murrell and I are making some progress with making mathematical expressions available in graphs. The idea is to use R expressions to represent the mathematical expressions. So far we have (or will soon have): R LaTeX x^i x^i x[i] x_i alpha \alpha Alpha \Alpha hat(x) \hat{x} \widehat{x} bar(x) \bar{x} \overline{x} x+y x+y x-y x-y x/y x/y (x) (x) {x} {x} frac(x,y)

Does anyone have experience with using the readline library in conjunction with ISO Latin1 characters? In response to a prod from Martin Maechler I am trying to convert R so that it will accept 8-bit characters (and render them correctly in text and graphics). This appears to work when I type such lines into a file and source it, but readline seems to intercept any 8-bit characters I type

When investigating the legend(x,y, expression ( <math>, <math> ), ....) [as suggested by Jim Lindsey], I once again stumbled over the fact that expression objects behave somewhat ``wierdly'', IMHO. We can have expressions of length(.) > 1, and access elements of these like list elements. However, other natural things don't work with expressions; some example

Dear useRs, I want to put a math expression in the ylab in my plot which should be a Delta and a 'y' with a trace and a hat above it and a 't' as subscription. How could I manage to do it? Thanks in advance, Regards, Rafael. ____________________________________________________________________________________ [[elided Yahoo spam]] [[alternative HTML version deleted]]

The .Options vector had been introduced a while ago after my suggestion (see Ross's E-mail below). .Options$digits is used be default in several print methods (eg print.lm), however, deparse(.) e.g., uses options()$width, and not .Options$width. Another problem is that .Options is still not in the documentation (on-line help). Before one could add it there, we'd need ``the

hello users of the SN package, i thought i post here some useful help on R code on the 4 moments for the skew t sampling gives seldom good results for skewness and kurtosis, so one really needs the analytical results, it took me some time to get it from the article Azzalini, A. & Capitanio, A.

This code below produces empty XXX.png files - if I use plot(), it works and if I enter the commands png(filename=fn) bubble(positions, do.sqrt=FALSE, main=q) dev.off() manually, it works as well. I am lost - any help appreciated. The weird thing is that it worked before I made some changes... (I don't have a copy of the working version...). R version: platform i686-pc-linux-gnu arch

Dear help I have been attenpting to compile R0.49 on both of these unix machines and have had no compilation errors but core dumps at run time.

Ok, I did the following experiment dyn.load("/usr/local/lib/libf2c.so.2.0") dyn.load("try.so") .Fortran("try", 10.5) where try.so contains the following compiled subroutine subroutine try(x) double precision x write(*,*) x return end It worked just fine (at least here on my FreeBSD machine at home). So it seems that it will be

I'm trying to write some code that throws a few expressions around the place, and I've boiled down the problem to be equivalent to this. Consider the curve function which plots expressions in 'x': > curve(x^2) Now wrap that in the most naive wrapper function: > fc=function(m){curve(m)} and try it: > fc(x^2) Error in eval(expr, envir, enclos) : Object

Hello, I am trying to get a time derivative on a plot title. I prefer to have it in the form \dot{s_i}, but \partial s_i/\partial t would be O.K. In the graphics demo I cannot find either a dot or a partial equivalent.
