r package to solve for Nash equilibrium
Is there an r package out there that solves for pure strategy* Nash
equilibrium of a two-person game*? A search for Nash equilibrium in r
provides a link to the *GNE* package which solves for the Generalized Nash
equilibrium. But what I would like to solve is a pure strategy Nash
equilibrium.

Nash equilibrium and other game theory tools implemented in networks using igraph or similar
Does anyone know of some code, and examples that implement game theory/Nash
equilibrium hypothesis testing using existing packages like igraph/statnet
or similar?
Perhaps along the lines of this article:
Zhang, Y., Aziz-Alaoui, M. A., Bertelle, C., & Guan, J. (2014). Local Nash
Equilibrium in Social Networks, *4*, 6224.

Nash equilibrium and other game theory tools implemented in networks using igraph or similar
Hello Chris,
I was implying you are capable enough to implement it, while you have
already identify a research paper. If there is no package out there,
uploading to CRAN would help future user too. I am more than happy to
help if you want to implement from scratch.
Best,
Mehmet

Predator Prey Models
Dear R-users,
I am currently modifying a previously developed predator prey model and
was curious if there was a way to add in a disturbance to the model (let's
say at time t=100). The disturbance can be the introduction of 40 prey
(N=40) and 10 predators (Pred = 10). I would like to see my model go from a
state of equilibrium (up to t = 99), show this disturbance (at t = 100) and
then

Why don't you implement and uplad the package to CRAN?

Markov transition matrices , missing transitions for certain years
Hi all,
I am working for nest box occupancy data for birds and would like to
construct a Markov transition matrix, to derive transition probabilities for
ALL years of the study (not separate sets of transition probabilities for
each time step). The actual dataset I'm working with is 125 boxes over 14
years that can be occupied by 7 different species, though I have provided a

remove from column a group of elements I have in another vector
Hi,
I have a data frame and I would need to remove from one of

In SQL I would use where

In what way does reminding people that packages exist because others just like them contributed something count as being uncivil? Terse, perhaps, since it bypassed the obvious suggestion to use a search engine, but not rude.

Markov chain transition model, data replication project
Hello all,
I am currently attempting to replicate data from a political science article
that utilized a Markov chain transition model to predict voter turnout
intention at time *t*; the data was separated into two different models
based on whether prior intent was to vote or not to vote. The details don't
really matter.
Mostly I am curious how to run a Markov chain transition model in R,

"Nash Equilibrium"
Dear R experts:
I searched cran (and r-help) for "nash equilibrium" and "game" but
nothing stuck out. has someone written a numerical nash optimizer for
two players?
player a has choices x1,x2,x3,... and cares about (maximizes)
pa(x1,x2,x3,...,y1,y2,y3)
player b has choices y1,y2,y3,..., and cares about (maximizes)
pb(x1,x2,x3,...,y1,y2,y3)
I can tune it to my problem, but

Probability(Markov chain transition matrix)
Hello, My name is Maria, MBA student in Sanfransisco, USA.
In my credit scoring class, I have hard time making "transition matrix",
which explains probability especially in relation to "Markov chain model".
It is regarding people's monthly credit payment behavior. Does R have
function to caculate it? I am actually a novice in using 'R'. Please help
me!!!

I responded to the unhelpful suggestion "Why don't you implement and uplad the package to CRAN?" No mention of a search engine. Is this what you are commenting on Jeff?

Nash equilibrium and other game theory tools implemented in networks using igraph or similar
Thanks I too wondered about the tone. The first suggestion was that I
should "google it" and the second, write my own code. I think if I did I'd
be reinventing the wheel, (and it'd be a big challenge for me). Also, I
have been searching and not found such code, despite evidence that it has
been coded (just not sure if it was in R). BTW I did write to authors of
the article I

saving plots
Hi all, I am have an R script that makes many plots, and I would like to
string them into a movie file. To do that I have to save all of my plots as
jpegs or gifs. I don't want to go through all of my plots and save them by
hand though. Is there a way to automate saving the plots as a gif or a jpeg
so I can string them into a movie?
Thanks in advance

cat bailing out in a for loop
Dear All,
I am trying to calculate the Hardy-Weinberg Equilibrium p-value for 42
SNPs. I am using the function HWE.exact from the package "genetics".
In order not to do a lot of coding "by hand", I have a for loop that
goes through each column (each column is one SNP) and gives me the
p.value for HWE.exact. Unfortunately some SNP have reached fixation and
HWE.exact requires a

R package for estimating markov transition matrix from observations + confidence?
Dear R gurus,
I have data for which I want to estimate the markov transition matrix
that generated the sequence, and preferably obtain some measure of
confidence for that estimation.
e.g., for a series such as
1 3 4 1 2 3 1 2 1 3 4 3 2 4 2 1 4 1 2 4 1 2 4 1 2 1 2 1 3 1
I would want to get an estimate of the matrix that generated it

Making a markov transition matrix - more progress
I solved the problem in one more (and more elegant) way. So here's the
program again.
Where does R stand on the Anderson-Goodman test of 1957? I hunted
around and nobody seems to be doing this in R. Is it that there has
been much progress after 1957 and nobody uses it anymore?

# You are holding a dataset where firms are observed for a fixed

How to store a triangular matrix
Hello, I want to create a triangular matrix and only keep the lower triangle entries without having to allocate memory for the whole matrix, is there any way I can do something like
A<-matrix(data, nrow=50)
but for a triangular matrix?
Thanks
