Tk Rplot
Description
Placing R graphics in a Tk image.
Usage
tkrplot(parent, fun, hscale=1, vscale=1)
tkrreplot(lab, fun = lab$fun, hscale=lab$hscale, vscale=lab$vscale)
tkpersp(x,y,z, theta = 30,phi = 30,expand = 0.5, r = sqrt(3), ...)
.my.tkdev(hscale = 1, vscale = 1)
.make.tkindex()

Details
The function tkrplot creates and returns a Tk label widget
containing a Tk image of type Rplot. For now the size is hard-wired.
The plot is created by calling fun with a special device used
create the image.
The function tkrreplot calls fun to place a new plot
in the Rplot widget lab.
tkpersp is called like persp but produces a plot in
which some of the parameters of persp are controlled
graphically.
.my.tkdev and .make.tkindex are useful for defining new
functions like tkrplot.
Examples
## Not run:
## These cannot be run by examples() but should be OK when pasted
## into an interactive R session with the tcltk package loaded
tt <- tktoplevel()
bb<-1
img <-tkrplot(tt, function() plot(1:20,(1:20)^bb))
f<-function(...) {
b <- as.numeric(tclvalue("bb"))
if (b != bb) {
bb <<- b
tkrreplot(img)
}
}
s <- tkscale(tt, command=f, from=0.05, to=2.00, variable="bb",
showvalue=FALSE, resolution=0.05, orient="horiz")
tkpack(img,s)
