This is an inquiry for all those who have been working on external data base applications. I sent an inquiry (below) to snews about this sort of thing a couple of years ago and eventually decided that I would wait to see what external database developments occurred and then revisit the problem. I hope that foundations are now better. Suppose for the sake of concreteness you have a large

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'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:

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

About 2 percent of the time I use fix() to edit a function that is sitting in .RData I get the response: > fix(qss) Error in edit(name, file, editor) : problem with running editor vi when I try to close the editing session. I used to think that these were always cases where there was some syntactical error with the edited file, but this is not the case. I realize that one surefire way to

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

In the time honored spirit of wishing to do nothing well, could I suggest that the Splus (versions 5 and 6) response to: > rbind(NULL,NULL) NULL is preferable to the R response: > rbind(NULL,NULL) Error in rbind(NULL, NULL) : attempt to set an attribute on NULL This is on: platform sparc-sun-solaris2.8 arch sparc os solaris2.8 system sparc, solaris2.8 status major 1

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:

Was there ever a convenient method provided to add boxplots to the current plot at specified x values? There was a question by Martin Maechler some time ago here, but I could seem to find any satisfactory resolution of it. I see that there is an add=T option to boxplot and bxp, but I don't see how to set the x-values. url: http://www.econ.uiuc.edu Roger Koenker email roger at

I'm trying to port some routines from S to R. The code includes some fortran stuff that calls lapack. In the past in similar situations, but without any lapack calls, I've had success using simply, as in the V&R R-complements, R SHLIB -o rq.so *.f then in R dyn.load("rq.so") But now when the code is called from R, R crashes and I get a message

I've been writing some matrix-type methods for a new class of sparse matrices and for most methods this has been straightforward. However, there are examples, like %*% and chol, that (apparently) R doesn't automatically recognize as generic. What to do in these cases? At this point, I've been writing new generic methods with slightly perturbed names %m% and cholesky for example in

A new version of the quantile regression package (quantreg 3.09) is now available on CRAN. The new features include: 1. a new fitting method "fnc" for rq() which allow the call to specify linear inequality constraints on the coefficients. 2. an anova() function for rq objects that implements several F-like tests for quantile regression models at a given quantile, and other F-like

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

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: .

An extremely modest proposal: It would be nice if packages could have a FAQ and if faq(package.name) would produce this faq. And if, by default faq() FAQ() would produce the admirable R faq... Apologies in advance if there is already a mechanism like this, but help.search() didn't reveal anything. url: www.econ.uiuc.edu/~roger Roger Koenker email rkoenker at

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.

Hi, I have been trying to dyn.load a library (rq.obj), which will allow me to run a quantile regression function, but so far unsuccessfully. I have tried under windows 98 and R 6.24: 1) dyn.load("d:\\...\\rq.obj") 2) dyn.load("d:\...\rq.obj") 3) 1 and 2 accounting for case sensitivity. 4) dyn.load("d:/.../rq.obj") 5) Place the files in the directory where from I

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?
