Installing ‘intergraph’ package

After some e-mails I decided to put together a bit more detailed instruction how to install the ‘intergraph’ package together with the namespaced version of the ‘network’ package. See here. There seemed to be some problems with downloading the namespaced ‘network’ from my webstite (thanks Neil!). File permissions were set incorrectly. I fixed that and

Namespaces and name conflicts

R packages ‘igraph’ and ‘network’ are good examples of two R packages providing similar but complementary functionalities for which there are a lot of name conflicts. As for now the ‘igraph’ package has a namespace while the ‘network’ package (version 1.4-1) does not. This became an issue when I was working on the ‘intergraph‘ package.

From igraph to network and back again

In an effort to achieve this (last paragraph), I created a couple of functions to coerce networks as ‘igraph’ objects to networks as ‘network’ objects and vice versa. I wrapped them into a package called ‘intergraph’ which I just uploaded to my personal miniCRAN. Please mind, this is still an experimental version! Might be bug-infested.

Social contagion? Maybe not…

Recently there was a lot of racket about results presented in papers by a pair Nicholas Christakis & James Fowler. Their papers gained a lot of attention both in the academic world as well as in media. In their papers they claim to provide evidence for social contagion (transmission through social networks) of several types

What Social Network Analysis software do you use?

See a the poll here by Gabriel Rossman at Code and Culture. I voted for R and ‘igraph’. If you use R you are getting access to all the other wonderful things that come with R. Using specialized package, like Pajek, UCINET etc requires constant going back and forth between network software and some other

R’s working directory

Do you usually start R with a desktop icon or some other shortcut? Are you tired of using setwd and getwd each time after you start R to get the working directory correctly? If so, then your days of suffering might be just coming to an end. Having the working directory set correctly is very

maps of Poland in R

Bogdan Taranta (website in Polish) is developing a set of functions for drawing administrative maps of Poland. I wrote similar functionality for myself already some time ago, but only for voivodships, i.e. top-level administrative units, and also in a rather low resolution. Bogdan’s contribution seems to contain all levels, at high resolution, and including the
