R experts:
I want to prepare a demo (that will play sequentially in clicks) for a
presentation tutorial...Can somebody help me how can I write a demo, suppose
the following are steps in the demo..
#start
set.seed(1345)
x1<- sample(letters[1:10], 5)
x1
sort(x1)
x<- sample(1:10, 5)
y<- sample(c(11:20), 5)
require(lattice)
plot(x,y)
z<- rnorm(5, 1, 0.5)
dataframe<- data.frame(x, y, z)
model1<- lm(y ~x)
aov(model1)
#end
Please help me, I could not get proper function / package to it.
I would use the tcltk package for this, but it does mean you need to
learn the TCL/TK language. For example, I have used this in a presentation:
demos <- function() {
base <- tktoplevel()
tkwm.title(base,"Demos")
font <- "{Arial 24}"
tkpack(tkbutton(base, command=PointCloud, text="Point cloud",
font=font), side="left")
tkpack(tkbutton(base, command=Volcano, text="Volcano", font=font),
side="left")
tkpack(tkbutton(base, command=ChangeColour, text="Change colour",
font=font), side="left")
tkpack(tkbutton(base, command=SmoothingDemo, text="Smoothing",
font=font), side="left")
}
PointCloud, Volcano, ChangeColour, and SmoothingDemo are regular R
functions, called with no arguments when you click on their button.
