Greetings, I'm organizing summer econometrics lunch meetings to discuss thesis work. The first meeting will be this friday July 18 12-1pm in the conference room on the third floor of Wohlers.

I have a vector of logLik values that I'd like to return and it would be nice if the the print method didn't run them together. Could I make a plea for using sep = " ", rather than sep = "" in print.logLik? url: www.econ.uiuc.edu/~roger Roger Koenker email rkoenker at uiuc.edu Department of Economics vox: 217-333-4558

We have a solaris/sparc machine that has been running an old version of R-devel: Version 2.2.0 Under development (unstable) (2005-06-04 r34577) which was built as m64 from sources. Attempting to upgrade to 2.4.0 the configure step goes ok, but I'm getting early on from make: > gcc -m64 -L/opt/sfw/lib/sparcv9 -L/usr/lib/sparcv9 > -L/usr/openwin/lib/sparcv9 -L/usr/local/lib -o

I am trying to make R-1.5.0 from source on a new G4 system with the apple developer tools and X11 installed and with ATLAS. Running ./configure appears to end normally, but running make yields: gcc -no-cpp-precomp -I. -I../../src/include -I../../src/include -I/usr/local/include -DHAVE_CONFIG_H -g -O2 -c Rdynload.c -o Rdynload.o Rdynload.c: In function `R_FindSymbol': Rdynload.c:942:

I've been playing with a quincunx animation in R 1.2.2 and would like to have finer control over the speed of the animation. I know that I can use system("sleep 1") on unix systems at least, but it would be nice to have something like pause(.01). Any suggestions? url: http://www.econ.uiuc.edu Roger Koenker email roger at ysidro.econ.uiuc.edu Department of Economics vox:

Does anyone have (good) experience converting tables of tournament results into dendrogram-like graphics? Tables, for example, like this: read.table(url("http://www.econ.uiuc.edu/~roger/research/ncaa/NCAA.d")) Any pointers appreciated.

I sent the message below to r-sig-mac yesterday, but having no reply I decided to explore a bit myself and found that editing: /Library/Frameworks/R.framework/Versions/2.3/Resources/share/make/ shlib.mk yzzy: diff shlib.mk shlib.mk~ 3c3 < include $(R_HOME)/etc/Makeconf --- > include $(R_HOME)/etc${R_ARCH}/Makeconf restored the functionality of R CMD INSTALL. Is this a known issue?

I've been trying to figure this out for a while, but my knowledge of R is obviously still too limited. The context is as follows: I have some time series, and I would like to estimate their densities, and then use the actual densities in a monte carlo simulation. Now, I can easily estimate the density using density(); I can write a random number generator to fit an arbitrary density

I've had a play with this and, due to my own short-comings, remain none the wiser. In particular, I'm not sure what value of 'spar' is consistent with the magic lambda=1/1600 for quarterly data. I initially interpreted spar as lambda and tried setting spar=1/1600. This results in almost no smoothing while spar=1600 causes an error. The smooth.spline function seems to want

We have recently upgraded to Solaris 10 on a couple of sparc machines with the usual mildly mysterious consequences for library locations, etc, etc. I've managed to configure R 2.1.0 for a 64 bit version with: R is now configured for sparc-sun-solaris2.10 Source directory: . Installation directory: /usr/local C compiler: gcc -m64 -g -O2 C++

Hi. I am aware of three different R packages for linear programming: glpk, linprog, lpSolve. From what I can tell, if there are N variables and M constraints, all these solvers require the full NxM constraint matrix. Some linear solvers I know of (not in R) have a sparse matrix input format. Are there any linear solvers in R that have a sparse matrix input format? (including the

In ancient times, circa 1980, S data directories were called swork and sdata not .Data, and "New-S" as described in the already medieval "Blue Book" discusses a function DBCONVERT that converted swork data into .Data data. It is embarrassing to admit it, but I still have data archives from a BTL machine called alice in the swork format and would like to convert a dataset to

I'm trying to install the current R-devel on a G4 powerbook.

We've recently "upgraded" a server to solaris 8, and in reinstalling R I've encountered a problem in getting it to recognize the readline library. I have installed readline in what I believe to be the "usual" place: /usr/local/lib with include files in /usr/local/include/readline. But ./configure produces: ragnar.econ.uiuc.edu# grep readline hout checking for

I'm having problems with environments and update() that I expect have a simple explanation. To illustrate, suppose I wanted to make a very primitive Tukey one-degree-of- freedom for nonadditivity test and naively wrote: nonadd <- function(formula){ f <- lm(formula) v <- f$fitted.values^2 g <- update(f, . ~ . + v) anova(f,g) } x <-

What is the current state of the R-art for ordered probit models, and more esoterically is there any available R strategy for ordered cauchit models, i.e. ordered multinomial alternatives with a cauchy link function. MCMC is an option, obviously, but for a univariate latent variable model this seems to be overkill... standard mle methods should be preferable. (??) Googling reveals that spss

I have a pdf scan of several pages of data from a quite famous old paper by C.S. Pierce (1873). I would like (what else?) to convert it into an R dataframe. Somewhat to my surprise the pdf seems to already be in a character recognized form, since I can search for numerical strings and they are nicely found. Of course, as is usual with such tables there are also headings and column
