...nonparametric regression and density estimation, something like \hat{f'}(x) [LaTeX] is very natural. In all S dialects, hat(f') is invalid syntax, and hence one cannot use something like plot(1, main = expression(hat(f'))) I can say something like plot(1, main = expression(widehat(paste(f, "'"))), cex.main = 3) but that (the R code, not the plot result) is a bit ugly.

...sub- or superscripts. For instance, for the expression 'b[hat(a)]' the hat() seems to shift 'hat(a)' too much to the right of 'b'. Try the below example and you'll see what I mean: label <- list( expression((b[sqrt(a)])), expression((b[bar(a)])), expression((b[widehat(a)])), expression((b[widetilde(a)])), expression((tilde(a))), # Problematic: expression((b[dot(a)])), expression((b[ring(a)])), expression((b[hat(a)])), expression((b[tilde(a)])), expression((b^dot(a))), expression((b^ring(a))), expression((b^hat(a))), expression((b^tilde(a)))...

Is there anyway to label axes in 3D plots with mathematical expressions? In the code below, I want to replace "delta_yrsed" with what "\Delta \widehat{yrsed}" represents in TeX, but the [xyz]lab parameters of title3d appear to only accept character strings. require("rgl") fn.delta.yrsed <- function(dist, delta.dist, beta.dist=-0.1376463, beta.dist2=0.0088698) { delta.yrsed <- (beta.dist + 2*beta...

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) \frac{x}{y} cdots \cdots ldots \ldots We are wondering how far to go with this process. Does the above cover what people want, or are there important omitted features (we don't really want to do...
