Adventures with Comcast: Part ohnoesnotanotherone in an ongoing series
Regular readers of this blog (yes, both of you!) may remember the computer/broadband/ directory that this post appears in as the collection of my Comcastic (yeah right) experiences with my ISP.
But I think this week may top everything. I'll just try to jot down some notes before I forget all the gory details:

Sorting a matrix/data.frame on a column
mat.sort <- function(mat,n) { mat),] <- mat return(mat) } a <- matrix(rnorm(100),ncol=10) mat.sort(a,1)
useR! 2006
Last week, I attended the 2006 UseR! conference: here is a (long) summary of some of the talks that took place in Vienna -- since there were up to six simultaneous talks, I could not attend all of them... In this note: 0. General remarks 1. Tutorial:...
R graphics
I just finished reading Paul Murrel's book, "R graphics". There are two graphical systems in R: the old ("classical" -- in the "graphics" package) one, and the new ("trellis", "lattice", "grid" -- in the "lattice" and "grid" packages) one. The first...

Use R 2009 Conference
I did not attend the conference this year, but just read through the presentations. There is some overlap with other R-related conferences, such as R in Finance or the Rmetrics workshop. http://www.agrocampus-ouest.fr/math/useR-2009/ http://www.rinfin...
Decimal log scale on a plot
R only does natural (neperian) log scales by default, and this is lame. Here is a simple code to do decimal log scale, pretty much a requirement for scientists… The force(x/y)lim options works for natural and log scales (for the later case, you need to specify the power of 10 that you want : c(-2,2) 
Long R, Short Excel
R is very speedy statistical package that's like an F-18A Hornet, versus Excel which is like a paper airplane. R is professional sports, Excel is Pop Warner. R is Mona Lisa, Excel is stick figures. R is ... okay, you get the idea. I'm long R, and short...
