First, my site will be down December 27-28 because of a network upgrade at Penn. It will also be down at least one day before that, while I upgrade the operating system. (And another day some time in January because of a planned power outage.) Second, I have replaced the search engine in my R site: http://finzi.psych.upenn.edu/ I am now using Namazu instead of HtDig. The direct link to the

[If I knew who to report this to privately, I would. Sorry to embarrass anyone who's just trying to contribute to the R-project.] There seems to be some oddities with the RSiteSearch web page. When I enter 'RSiteSearch("console")' I'm taken to http://search.r-project.org/cgi-bin/namazu.cgi?query=console&max=20&resu

Hello 'R' Users, I am very new on 'R', so excuse me if I ask something wrong. I have ASCII data and the colums of the data are looks like :- !------------------------- time,yr,mo,dy,hr,min,sec,lat,lon,ht,co2obs,sigma,co2model -- - -- !---------------------------- Each column has data value. Now I want to produce 2-d color maps, for example the plot should look like :- on

I tried to search for a string of words ``as one entity'' following the example in the help file: > RSiteSearch("{logistic regression}") and got the error message: 2008-09-11 08:55:41.356 open[823] No such file: /Users/rturner/http:/ search.r-project.org/cgi-bin/namazu.cgi?query={logistic+regression}

Unfortunately, I am unable to get this search site working again. (The message below explains why I had to rebuild it.) The computer worked for the better part of a day downloading and installing all the help files from all CRAN packages. Somehow it failed to get the vignettes this time. But I pushed ahead and ran the part of namazu that makes the search indices: mknmz. And you can see the

hi,R users, Now I have some scatter figures, is there some method can plot equalprobable error ellipse ? -- TANG Jie Email: totangjie@gmail.com Tel: 0086-2154896104 Shanghai Typhoon Institute,China [[alternative HTML version deleted]]

Hello! I need to use Kruskal-Wallis test and post-hoc test (Dunn's test) for my data. But when I searched around, I only found this function: kruskal.test. But nothing for Dunn's test. So I started to write one myself. But I do not know how to count ties in the data frame. I can use for loops but it seems long and unnecessary since the rank function actually knows the ties. So

Dear R list, For some reason I am unable to access neither search.r-project.org, nor http://finzi.psych.upenn.edu/ so I cannot search the archives for a possible answer (I Googled for this but didn't find anything). Is it possible to draw barplots using a texture instead of colors, for a black and white printer? TIA, Adrian -- Adrian Dusa Arhiva Romana de Date Sociale Bd. Schitu

hi, r users i have a problem with KNN. i have 2 datasets, X0 and X1. >dim(X0) >1471*13 dim(X1) >5221*13 and for every instances in the dataset X1, i want to find the nearest neighbour(1nn) in the dataset X0. and i dont have the true classifications of dataset X1. but the function knn() need true classifications(cl) to do prediction. i just curious if there are some other function

I've made a few changes in the indices in my R search site. http://finzi.psych.upenn.edu is the general URL, and RSiteSearch takes you to http://finzi.psych.upenn.edu/search.html, which is equivalent to http://finzi.psych.upenn.edu/nmz.html. The main change is that I have eliminated "Previous message" and "Next message" from each page. (I still have "Next in

Good morning all! I am attempting to superimpose a moving-average smoother onto a graph of daily plots. These plots (in table[,2] below) span about 350 days and looks very noisy. I'd like for this smoother to plot the average of each group of 7 consecutive days (weekly) and show a line which joins these series of averages. Given the definition of MA, the first and last points will

Dear R user, I am working with LOO. Can any one who is working with leave one out cross validation (LOO) could send me the code? Thanks in advance Alex [[alternative HTML version deleted]]

Is there a function in R that will allow me to estimate the sample size required from count data (poisson data?), given the known variance and desired margin of error and confidence interval? My specific data set will be based on a survey of hikers that will be asked about the number of animals of species 'x' they observed during a given period. I need to know the number of hikers

Is there any R package addressing problems of constrained optimization ? I have the following "apparently" simple problem: Given a set V with fixed cardinality: nv Given a set S whose cardinality is a parameter: nHat Let the cardinality of the intersection S.and.V be: nHatv The problem consists of maximizing nHatv/nv subject to a penalty if nHat >

Dear R users, I'm trying to extract from a given matrix (GROUP) the coordinates of the vertices of the different groups (i.e. 3, 7, 1 . . .) to plot the polygons to delineate the area in which each group "wins" and colour it diferentially. I can make a simple point plot, but I would like to add polygons with full colored area. The example is with a 5x5 matrix, but I'm working

Dear R members, I would like to know if there is a stepwise function that gives LRT value instaed of AIC? thanks in advance, Luciana Pozzi CENPAT-CONICET Argentina [[alternative HTML version deleted]]

Hello everybody, after searching around for quite some time, I haven't been able to find a package that provides a function to compute the Windorized mean and variance. Also I haven't found a function that computes the trimmed variance. Is there any such package around? thanks, Roberto

I am trying to convert numbers to English words, e.g. 123 -> One hundred twenty three. After some searching, I have been unable to find any info on this. I could certainly write code to do it, but my question is this: Does anyone know of a function that does this? Thanks, Derek McCrae Norton

Hello, I am very new to R. I would like to plot astronomy data by right ascension, declination, and various "distance" values, such as redshift and comoving distance, in 3D. Is there any 3D polar plotting functions? I can't seam to locate any information on whether it exists or not.
