Dear Hisaji
Thank you very much for the codes. I expect that you or someone
develop someday the function of continuous cartogram using newly
proposed Inoue's methods as shown at

Inoue's PhD dissertation is available at

Non-Contiguous Area-based Cartogram

Hello.
Sorry I'm not "Dr."
Here is my Non-Contiguous Area-based "Shrinking"
Cartogram script for maptools.
This script doesn't support multi-parts polygon shape.
Please try this.

Hi,
In the days when I had more time to work on this stuff I looked into
programming continuous cartograms for maptools. If I remember correctly
Danny Dorlings
approach produced really nicely arranged circualr cartograms. I also
remember
that the optimization he used was fairly inefficient and cou

I guess it come from Rmap package. You may use Rmap or write a same
function with maptools.
As for cartogram, I have rewritten the cartogram code in accordance

Dear Nicholas and members
Since those examples in wiki are not my works, it is better to ask the
author, Dr. Ono, who is one of members in this mailing list.
However, cartograms are annoyed issue as mentioned in my talk

Dear Malcolm and R-sig-Geo members
Map object from shapefiles with read.shape() can be merged or
clipped. Here are examples written in Japanese but the code is
universal.
For clipping

Yes, it
I am using the packages shapefiles, and maptools in R
to visualize data from shapefiles, dbf files, and census data.
My question is this, is it possible once a shapefile
is read into R, to edit the contents of the shapefile?
Let me give a practical example.
I am using a shapefile of ele
