Hi. I am trying to install a package called DMwR http://cran.r-project.org/web/packages/DMwR/index.html located here: http://cran.r-project.org/bin/windows/contrib/r-release/DMwR_0.2.1.zip on windows 7. I am using R 2.10.1. I also tried typing something like this but it did not work well. install.packages(c(" http://cran.r-project.org/bin/windows/contrib/r-release/DMwR_0.2.1.zip

Hi, I am running an environment with 15 FreeBSD servers on which I want to maintain ports, rc.conf settings, and assorted configuration in /usr/local/etc/. Looked around the existing Puppet docs, I got a puppetmaster and a test client to work and install a package as specified in the site manifest. This is very basic but awesome! I want to create a puppet FreeBSD HowTo that addresses a

The following is a simple example with a poor solution that shows my difficulties with scope. The function /logit.test /has 3 arguments: /model.start,/ an initial model; /model.finish/, an all-inclusive model, /my.data/, a dataset, in this case trivial. There are 2 function calls in l/ogit.test,/ first to /glm/ to get an initial fit (local variable /logit/) using /model.start;/ then a call

Hi, My initial setup for receiving faxes worked as follows: fax call arrives on ISDN BRI connected to a BOSCH PBX, signal sent to ALCATEL PBX via PRI QSIG then finally sent to ASTERISK via PRI EUROISDN. The Asterisk server then forwarded the call to a iaxmodem and HylaFax received the data. All worked fine. Now I got rid of both BOSCH and ALCATEL in the "fax path" and it's as

Hi, Given a frame with calendar date's: "2005-07-01", "2005-07-02","2005-07-03","2005-07-04","2005-07-05",etc. I want to extract the following from these dates: week number month number year number Any ideas how to accomplish this? Many thanks. Regards, Richard

It is not a pure R question,but I hope some one can give me advices. I want to use analysis my data with the multilevel model.The data has 2 levels---- the second level has 52 units and each second level unit has 19-23 units.I think the sample size is quite small,but just now I can't make the sample size much bigger.So I want to ask if I use the multilevel model to analysis the data set,will

data from multilevel units,first sample the class ,and then the student in calss.following is the 2-level model. and the level-1 model deals with the student,and the level-2 model deals with the class level the students belong to. Level-1 Model Y = B0 + B1*(ZLEAD) + B2*(ZBUL) + B3*(ZSHY) + R Level-2 Model B0 = G00 + U0 B1 = G10 + G11*(ZWARMT) + U1 B2 = G20 + G21*(ZWARMT) + G22*(ZABLET) +

Dear Sirs, I am Professor at Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh, India. While taking classes, I found the *by() *function producing following error when I use FUN=mean or median and some other functions, however, FUN=summary works. Given below is the output of the example I used on a built-in dataset "mtcars", along with error message reproduced herewith: >

i study the code of function ave,but i can understand one line of the syntax. > ave function (x, ..., FUN = mean) { n <- length(list(...)) if (n) { g <- interaction(...) split(x, g) <- lapply(split(x, g), FUN) } else x[] <- FUN(x) x } my question is : what does "split(x, g) <- lapply(split(x, g), FUN)" mean? thank you! --

The green book tells:"The basic technique is classic :keep it simple ."A long ,complicated expression or function is less fravorable than" a relatively small computations that combines calls to a few other functions to perform its tasks." But I don't get the point totally.Can anyone give me an example to make me understand this rules totally? ps: Is it mean that f1 is

Hello, I have tried to upgrade R to 4.0. I have added `deb http://cloud.r-project.org/bin/linux/debian buster-cran40/` to `/etc/apt/sources.list` (but I removed cran35). Btu when I run `apt-get update; apt-get install r-base r-base-dev` I get an error. I think it depends on r-base-core, since it depends on these obsolete libraries: ``` $ sudo apt-get install r-base-core Reading package lists...
