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.

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

I don't think OP asked an unreasonable question at all.

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.

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

Nash equilibrium and other game theory tools implemented in networks using igraph or similar
There are many possible responses to the question "Is there a package to do X." Some that I can imagine are:
* Yes, see package Y...
* No, I am familiar with all 10000 packages and there isn't...
* Silence (because no one who is paying attention is familiar with the one that exists)
* Use a search engine...
* You are a jerk because you did not use a search engine
* Packages exist

list assignment syntax?
Dear R wizards: is there a clean way to assign to elements in a list?
what I would like to do, in pseudo R+perl notation is
f <- function(a,b) list(a+b,a-b)
(c,d) <- f(1,2)
and have c be assigned 1+2 and d be assigned 1-2. right now, I use the clunky
x <- f(1,2)
c <- x[[1]]
d <- x[[2]]
rm(x)
which seems awful. is there a nicer syntax?

big quasi-fixed effects OLS model
dear R experts---now I have a case where I want to estimate very large
regression models with many fixed effects---not just the mean type, but
cross-fixed effects---years, months, locations, firms. Many millions of
observations, a few thousand variables (most of these variables are
interaction fixed effects). could someone please point me to packages, if
any, that would help me estimate such

fast lm se?
dear R experts---I am using the coef() function to pick off the coefficients
from an lm() object. alas, I also need the standard errors and I need them
fast. I know I can do a "summary()" on the object and pick them off this
way, but this computes other stuff I do not need. Or, I can compute (X'
X)^(-1) s^2 myself. Has someone written a fast se() function?
incidentally, I think

lm without error
this is not an important question, but I wonder why lm returns an
error, and whether this can be shut off. it would seem to me that
returning NA's would make more sense in some cases---after all, the
problem is clearly that coefficients cannot be computed.
I know that I can trap the lm.fit() error---although I have always
found this to be quite inconvenient---and this is easy if I have only

print.data.frame to string?
dear R experts---is there a function that prints a data frame to a string?
cat() cannot handle lists, so I cannot write cat("your data frame is:\n",
df, "\n").

on abort error, always show call stack?
Dear R Wizards---is it possible to get R to show its current call
stack (sys.calls()) upon an error abort? I don't use ESS for
execution, and it is often not obvious how to locate how I triggered
an error in an R internal function. Seeing the call stack would make
this easier. (right now, I sprinkle "cat" statements everywhere, just
to locate the line where the error appears.) Of

parallelized version of "by" and "ave"
Dear R experts---
Has anyone written parallel versions of "by" (i.e., mcby) and "ave"
(i.e. mcave) ? I did ask a question like this a year ago, and then
the answer was no.
for those who are googling the group for the answer to this question,
in the meantime, the poor man's version of "by" is mclapply( split(
ds, factor ), FUN )
I don't know the poor

multicore by(), like mclapply?
dear r experts---Is there a multicore equivalent of by(), just like
mclapply() is the multicore equivalent of lapply()?
if not, is there a fast way to convert a data.table into a list based
on a column that lapply and mclapply can consume?
advice appreciated...as always.

different interface to by (tapply)?
dear R experts:
has someone written a function that returns the results of by() as a
data frame? ??of course, this can work only if the output of the
function that is an argument to by() is a numerical vector.
presumably, what is now names(byobject) would become a column in the
data frame, and the by object's list elements would become columns.
it's a little bit like flattening the by()

character strings with embedded commands: perl "/gee" ?
dear R experts---I am trying to replicate a perl feature. I want to be
able to embed R commands inside a character string, and have the
string be printed with the command executed. my perl equivalent is
my $a=10;
my $teststring = "the expression, $a+1, is ::$a+1::, but add one
more for ::$a+2::\n";
$teststring =~ s/::(.*?)::/$1/gee;
print $teststring;
of course, R does not use
