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()

Arguments

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.

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)
