similar to: understanding recursive functions

I am trying to understand the concept of lexical scope in "An Introduction to R" by the R Core development team. I'd appreciate it if someone would explain why the following example does not work: q <- function(y) {x + y}; w <- function(x){q(x)}; w(2); According to the discussion of Scope on page 46, it seems to me that R will interpret the free variable x in q as the

The following command, issued from the DOS command prompt (running Windows XP), produces the intended result of a .csv file created by program.R: ?c:\program files\R\R-2.8.0\bin\Rterm.exe? --save < "c:\TEMP\program.R" However, when I create a file called Rbatch.bat that contains exactly the line above, and try to execute it (by double clicking or via the Shell command in an Excel

Does anyone know if any R package has a function that will conduct Hollander's test of bivariate symmetry? (Hollander, Biometrika, 1971) Either the exact test or an asymptotic version would be sufficient for my purposes. Thanks.

The first program generates an error message and does not execute the regression of y on x. x<-1:10; y<-rnorm(10) + x; prac <- function( model, wghts ){ lm(model, weights = wghts) } prac(model = y~x, wghts = rep(1, 10)) But the next program works: x<-1:10; y<-rnorm(10) + x; prac <- function( y, x, wghts ){ lm(y~x,

When I run a macro that uses RExcel, I get a dialog box that says "Microsoft Excel is waiting for another application to complete an OLE action." There is no error in the RExcel commands in the macro, of that I am sure. The box appears to be related to the inclusion of RunRFile commands. The macro will run through the second RunRFile command, but will not execute the

I just installed R 2.12.1, and when I went to run a few old programs with it, nothing worked. I got a ton of error messages saying such and such package was built before R 2.10.0 and needed to be reinstalled. These were not just warning messages, but error messages that prevent the programs from running when they were running just fine with R 2.10.1 For some of those packages, such as deSolve, I

Well, hi folks: I am still having this problem with ices crashing regularly. I have upgraded to todays cvs for ices and icecast hoping that would take care of it but no such luck. I am not sure just what is going on. It seems to happen fairly often which is not exactly making my listeners happy. I will include the relevant portion of the ices.log below. I would appreciate any suggestions

Is there a package in R that can do a variability plot? A variability plot is a kind of categorized dot plot. (If there is a lot of data in each category, box plots are used rather than dot plots.) Usually, the categories are factor level combinations. All the dot plots appear in the same window; below the x-axis a hierarchy of factors shows which dot plot corresponds to which factor-level

I've just compiled and installed openssh-2.9.9p2 (compiled against openssl-0.9.6b using gcc-3.0.0) on a Slackware 7-based Linux machine (kernel 2.4.6ac2). The previously installed version was 2.9p2, compiled against openssl-0.9.6a, also with gcc-3.0.0, but with a different build of gcc-3.0.0. Everything seems to work fine except for one problem: passphrase matching for ssh2 keys

Many moons ago, Samba used to build perfectly on Linux. Ever since I upgraded from 2.2.3, though, I've had to hack the configure script to get it to build, because Samba's configure is utterly and unshakeably convinced that no file locking of any kind exists on Linux. Once so configured, it builds, tests and runs perfectly. Can anyone tell me why Samba started disbelieving in

I'm just in the process of upgrading from nut-2.4.1 to 2.4.3 on a dual-Xeon box running Solaris 10 amd64 (i686-pc-solaris2.10). I configured as follows: ./configure --prefix=/opt/nut --with-gnu-ld --with-serial --without-usb --with-cgi --with-gd-includes=-I/usr/local/include --with-gd-libs="-L/usr/local/lib -R/usr/local/lib -lgd" --with-user=nut --with-group=nut

This is not a NUT question per se ... or at least, I don't think it is. I just replaced the battery pack in my HP R3000XR; the new batteries were shipped with 90% charge, were at about 87% when they went in, and were up to 98% charge the next day. Last weekend, the server that runs NUT went down for no apparent reason, wiping out its boot blocks, corrupting its boot archive beyond

Greetings, I've just installed nut-2.4.1 on a Solaris 10 x86 machine to monitor a HP R3000XR UPS. SunOS babylon4 5.10 Generic_138889-08 i86pc i386 i86pc Solaris First of all, I encountered a single problem during the build. After configuring, drivers/Makefile ends up containing the following line: LIBNETSNMP_LDFLAGS = -R../lib -L/usr/sfw/lib -lnetsnmp -lgen [...] This is clearly

Buenas tardes, tengo dudas con el siguiente ejercicio que me han propuesto en un curso, no se si alguien podria indicarme como abordarlo, soy nueva en R y agradezco mucho su ayuda Identi car cuales son las variables que están contenidas en el data.frame. A continuación, transformar ese data.frame para que cada columna represente cada una de las variables. Usar los nombres Date, District y N.

My system is 5.6, with upgrades. I installed Java 6 from the Centos repository. It doesn't seem to have Java 7. I need the development package. How can I install Java 7 development safely? I imagine I will first have to uninstall Java 6. Thanks, John -- John J. Boyer; President, Chief Software Developer Abilitiessoft, Inc. http://www.abilitiessoft.com Madison, Wisconsin USA Developing

Dear all, let consider the following function: Fun1 <- function() { library(lattice) plot1 <- 1:10~1:10 pl1 <- xyplot(plot1) return(pl1$call$x) } In R 2.5.0 (or older version) we have > Fun1() plot1 but starting from R 2.5.1 until the latest R 2.8.0 we obtain instead > Fun1() NULL because pl1$call seems to be equal to xyplot() without arguments. Something like

Thanks to all of you who are answering my dumb questions about my new CentOS instgallation. I modified /etc/hosts, as the hostname man page seemed to suggest, and rebooted. The hostname is still localhost. I want to change it to jjb-centos. I also want to change the domain name to abilitiessoft.com Thanks, John -- John J.

Hi, there: As you all know, correlation is not a very robust procedure. Sometimes correlation could be driven by a few outliers. There are a few ways to improve the robustness of correlation (pearson correlation), either by outlier removal procedure, or resampling technique. I am wondering if there is any R package or R code that have incorporated outlier removal or resampling procedure in

I have just installed CentOS 5.6 from disk and updated it. 1. I would like to use telnet on my local network. How do I activate it? 2. How do I install Mercurial? it is not in the repository. 3. How do I install eclipse? It is also not in the repository. Thanks, John -- John J. Boyer; President, Chief Software Developer Abilitiessoft, Inc. http://www.abilitiessoft.com Madison, Wisconsin USA
