treemap for no hierarchical data

Question

I am new in R. I have a scenario, may be you can give me some hints.

I have a very simple vector:

dt<-c(4.94 , 4.84 , 2.89)

I would like to have a main square, with the area of 4.94, and then in this area the second square 4.84. Third square with the area of 2.89 should be in the second square (4.84)

How can I do this in R?

Answer 1

areas <- c(4.94 , 4.84 , 2.89) #vector of areas
sides <- sqrt(areas) #vectors of side lengths

plot(0,0,type="n",xlim=c(0,4),ylim=c(0,4),axes=F,ann=F, asp=1) #Blank plot
rect(0,0,sides,sides,col=1:3,border=1:3)

or centered:

plot(0,0,type="n",xlim=c(-2,2),ylim=c(-2,2),axes=F,ann=F, asp=1) #Blank plot
rect(-sides/2,-sides/2,sides/2,sides/2,col=1:3,border=1:3)

Is this what your looking for?
