Intro to R: lecture presentation
Hi All:
A couple of weeks back, I asked a question on the list that I was invited to provide an introductory lecture on R to a group of academicians in Kolkata. I thank all of you who had generously guided me in providing me web links and words to the wise.
Time to give back. I did the presentation on introduction to R and uploaded the presentation files at the following site:

Advice on visual graph packages
Hey, all. I'm looking for packages that are good at two things
1) Drawing directed graphs (i.e nodes and edges), both with single
and double headed arrows, as well as allowing for differences in line
width and solid versus dashed. Note: I've tried Rgraphviz here, but
have run into some problems (which seem fixable and I may go with it
in the end), and it doesn't satisfy need

sampling weights for lme
Dear All,
I have a complex survey data with observations having differing
probabilities of selection into the sample. I would like to run a
linear mixed effects model and also to use weighting that takes this
into consideration. As far as I know, however, the weighting option for
the lme command from nlme package (or glmmPQL from MASS, for that
matter) is related to heteroscedasticity. Is there a

Constructing groupedData objects in nlme - a little problem
Dear R-help,
I am trying to create groupedData objects using the nlme library. I'm
missing something basic, I know:
Here is the first example in ch.1 of Pinheiro & Bates (2000):
library(nlme)
x2=Rail$travel;x1=Rail$Rail;eg1=data.frame(x1,x2);eg1gd=Rail
print(eg1gd)
x11();print(plot(eg1gd))
femodel=lm(x2~x1-1,data=eg1gd)
print(femodel$coefficients)
Result:
x12 x15 x11

Lightbox and RJS
Hi,
I am trying to include lightbox functionality in my app, but there is
a slight complication. Apparently lightbox initializes all the links
to lightbox events on page load. However, in my case, some new links
to lightbox events will be rendered to the page through ajax events
(obviously this means after the page loads). So I figure I need to
find a way to call lightbox''s

Proposal for an alternative bugtracking workflow
The script queries **all** issues with specified labels and "notifies" on
each of those.
While this approach works, I doubt it would scale well if everyone is doing
this by hand. OTOH, building a service that does this for everyone might be
feasible, albeit non-trivial and it's not clear who should own this.
So overall having this supported by GitHub would mean a much better UX...

Has anyone managed to bypass or fix the ferret''s .dump method problem?
When I include acts_as_ferret my whole rails app just blows up because
of Ferret''s .dump method. Ex:

Proposal for an alternative bugtracking workflow
Well, it's not really critical for us _now_, because we have not switched
to github issues. And I can't really see any possibility of that happening
in the short-term, either.
Even once we do decide we want to move that way -- which we haven't yet
even done -- it'll be a long road to making it happen, and I suspect
there's many more critical missing features that we'll
