[R-sig-Geo] rescaling spatstat owin window

[Marcelino de la Cruz]

It depends on what do you exactly mean by "rescale". May be with 
dilation() or affine():

  plot(letterR, xlim=c(0,10), ylim=c(0,10), main="")
  plot(dilation(letterR, .2), add=T, border=2)
  plot(affine(letterR, mat=diag(c(2,2)),vec=c(-2,-.65)), add=T, border=3)

Cheers,

Marcelino
