Saludo gente, antes que nada gracias por la ayuda que puedan aportarme, soy iniciante en R, estoy usando el paquete Mice para realizar imputaciones múltiples sobre variables en su mayoría categóricas. El problema está que cuando expresó este comando imp <- mice(dataset,method="polr",maxit=1) donde el dataset es un data.frame me tirá este error : iter imp variable 1 1 pial1a

I'm running a linear model in R using the car package. I have a variable education, which i have recoded and regrouped to my wishes. However, R seems to place each element of that variable in alphabetical order. When I am running the model, don't I need the model order from lowest to highest to make an inference that a one unit change in one variable produced a one unit change in

Hi All: I have written an R search plug-in based on Prof Jonathan Baron's R search site. This Firefox/Netscape plug-in lets you search R sites and R discussion group archives directly from your Mozilla (Seamonkey) or Firefox or Netscape browser. Here is the link to the installer for the plug-in: http://arinbasu.bravehost.com/installer.html If you want the source files or have other comments

Hi All: A couple of weeks back, I asked a question on the list that I was invited to provide an introductory lecture on R to a group of academicians in Kolkata. I thank all of you who had generously guided me in providing me web links and words to the wise. Time to give back. I did the presentation on introduction to R and uploaded the presentation files at the following site:

Hi All: This follows my earlier post on webized slides on lecture presentation on introducing R. I learned that in Mozilla (Firefox) browsers, the slides did not show up. Sorry for the no show. As a reluctant windows user, I kind of carelessly clicked through Powerpoint to convert the presentation file to its html form, unwittingly leading to the mess. See if it got corrected now (I do not have

Hi All: I was recently working with a dataset on arsenic poisoning. Among the variables in the dataset, I used the following three variables to produce crosstabulations (variable names: FOLSTAT, GENDER, ASBIN; all three were categorical variables, FOLSTAT denoted follow up status for the subjects and had seven levels, GENDER denoted sex (two levels: male,female), and ASBIN denoted binarized

Hi All: Recently, I got a query how R compared cost-wise (cost of purchase, maintenance, and training manuals) with other proprietary statistical software programs (or programming environments). The request, verbatim: <--- begin quote ----> >> dear arin, >> >> can you please find out the price of the various >> prop. statistical >> packages that are in

Dear List: Somewhere in the R-Statistical Software website, I remember having read about using the opensource Bluefish editor with R. During a recent visit to the site, I could not find the link or reference. Also, when I searched the list archives (http://maths.newcastle.edu.au/~rking/R/about.html) for "bluefish", the search returned no result. Has anyone in the list used

Hi All: I came across the following problem while working with a dataset, and wondered if there could be a solution I sought here. My dataset consists of information on 402 individuals with the followng five variables (age,sex, status = a binary variable with levels "case" or "control", mma, dma). During data check, I found that in the raw data, the data entry

I'm a newbie. I've just installed Icecast2 and am streaming to it successfully via Nicecast (great app BTW). My problem is that the stream from Icecast2 comes through as an .m3u which does not correctly open on any of the Mac or Windows machines that I've tried. When broadcasting directly from Nicecast the file type is a .pls which both iTunes and WMP seem to deal with just fine

Hello, I'm looking for a method to estimate narrow sense heritability of traits in a RIL population. Papers I've checked either use either SAS or SPSS or do not give any details at all. I've found some reference to using variance components in ANOVA, using the kinship or wgaim packages, but I don't have a clue as to how to do any of this. Is there any way fro a very R illiterate

Hi All: I am working with a dataset on Arsenic toxicity, and I am trying to calculate the 20th, 40th, 60th, 80th, and highest percentiles for a variable, dietary Moisture (variable name dMoist). The inbuilt function quantile(dMoist) would print 0, 25th, 50th, 75th, and 100th percentile. Does there exist a function that can calculate xth percentile (where x = 10th, 20th, ... etc) values?

I am trying to install the game "Perfect World" (http://pwi.perfectworld.com/download) On my Mac using Wine. After going through the obnoxious process of installing wine (for me this took forever because I am hugely computer illiterate, but through this process I learned to find info in forums AND use the terminal! Go me!), PW did not work. It installed fine, it would even launch but

Hi, Is it possible to configure persistent desktop icons, e. g. shortcuts that users can't delete ? On most of my client desktops, I have some home-made shortcuts, like here for example : http://www.microlinux.fr/configurations.html The shortcut on the lower left corner of the screen launches the public library management system. Most of the users are quite computer-illiterate, and more

I have experienced a couple of power failures since installing CentOS 5, both while I was working on the system. The first time, several weeks ago, I thought there was some "feature" that I had never seen before but couldn't really put my finger on it. The power came back on after a few seconds and I never missed a beat. I also shrewdly forgot about the anomaly that I had

Im having a trouble understanding the config files setup even with some documentation ive read such as the handbook, maybe im just illiterate. Anyway do you think some one can point me to some examples of real config files. Such as IAX, Extensions, and Sip. I just cant grasp the concept for some reason. If someone would like to help me out, maybe even explain one on one? Thanks a lot

Hello to all, This is my first ever use of a mailing list so bear with my ramblings and illiterate prose. I have been using samba from 2.03 to 2.07 for over a year now. We run DHCP, WINS on the samba (acting as domain) box running Mandrake 6.0. Windows machines are running everything from Win95 up to Win2K. With Win2K I have problems with slow read/write, particularly for one application

Can I ask a couple of usage questions? (RedHat Linux 6.1, R-1.1) 1. This may just indicate I'm a dinosaur who can't leave SAS behind. I want to write programs and run them with source() to see what they do, then I would like to use the "up arrow" to go back through the commands that were in the file, fiddle them, see what they do, and so forth. Is there no way? SAS has a
