Hi,  I want to do regression in each group. I made the group the following way. Now I want to run regression in each of the three groups.. Suppose , x<-c(0.5578196,6.5411662,13.2728619,2.0217271,6.7216176,3.37220617,2.5773252,7.2600583,15.3731026,3.4140288,8.1335874,     15..6476637,4.3014084,9.1224379,18.5605355,4.7448394,11.9296663,18.5866354,12.3797674,18.7572812,2.70433816,2.88924220,

Hi! Can anyone please let me know what numerical integration procedure does the integrate function in package stats follow? Thank you in advance Shant [[alternative HTML version deleted]]

Hi, I am a new user of R 2.8.1. I use Tinn-R for code editing. I use a windows 2003 system with 1 GB RAM. I am interested to generate dashboard and reports based on data from MS Access. These reports need to be posted on a weekly basis to the web. The reporting interface should provide facilities for "what if" scenarios. Is it possible to interface R analysis results to good open

Dear all, I have encountered errors in compiling R-2.5.0 and R-2.4.0 in a linux machine (power-pc). I can successfully build it from the source code if I do not use the '--enable-R-shlib' option while executing the './configure' command as mentioned in rpy documentation. Using the `--enable-R-shlib' option the configure step is executed properly but the `make' crashes

Dear R users, I am using spatstat to analyze point patterns (tree locations). I would like to import the shapefile with the study area polygons (six total) into R and use it to create the window for the spatstat analysis. I do not simply want to use a rectangle because the study areas spread out over 40000 ha. Any suggestions would be greatly appreciated. Thanks, Charlotte Reemts Charlotte

Hello, I am Souradeep Chattopadhyay and I am a graduate student at Iowa State University Department of Statistics. Can anyone please explain the mathematical formulation behind the scaling matrix returned by the qda function in MASS package. I want to understand how this scaling matrix is derived from the inputs given to the qda function. Example Code The following example is using

Hi, I have spatially autocorrelated data (with a binary response variable and continuous predictor variables). I believe I need to do an autologistic model, does anyone know a method for doing this in R? Many thanks C Bell

Hello! I'm a college undergrad desperately trying to finish up my thesis. I have a dataset on the distribution of a grassland bird from the Breeding Bird Survey. I have a very straightforward and simple version of the logistic growth model to describe changes in this bird's abundance over time. The variables are the natural birth rate, mortality, and carrying capacity. The equation itself

Hi guys, I need your help. I would like to select a subset from a dataset. This is the dimension of the dataset. > dim(data1) [1] 72 36 1916 so, it's like.. there are 1916 of 72 * 36 matrix. ==> looks like 72 * ( 36*1916 ) ** *1)* And I would like to select the first 72*36 matrix. This is how I did: > two=data1[,1:36] Error in data1[, 1:36] : incorrect number of dimensions

Hello, I've just carried out my first good-looking model using glmmPQL, and the output makes perfect sense in terms of how it fits with our hypothesis and the graphical representation of the data. However, please could you clarify whether my degrees of freedom are appropriate? I had 106 subjects, each of them was observed about 9 times, creating 882 data points. The subjects were in 3

Hi all, with regard to LUKS; should it placed before LVM or after? Any recommendations? TRIM command fully supported through all layers etc? -- Leon

Hi, When I reply to a post, it generally appears as a separate thread, rather than branching off the original post. Anyone know what I'm doing wrong? Noting I am currently receiving a couple of the lists in digest form. kind regards -- Charlotte Maia http://sites.google.com/site/maiagx/home

Hi All, How do I add "com" to the row names of a data frame, without deleting the plot numbers? Thanks

Hello! I have a dataset with the following two vectors: year<-c(1967,1968,1969,1970,1971,1972,1973,1974,1975,1976,1977,1978,1979,1980,1981,1982,1983,1984,1985,1986,1987,1988,1989,1990,1991,1992,1993,1994,1995,1996,1997,1998,1999,2000,2001,2002,2003,2004,2005,2006,2007,2008,2009)

Dear R users: is there a package, similar to varclus in SAS or varclus in S, ported or written for R? Also, is there any other package in R that was designed for grouping the variables under different measures of distance (in cases where data is non-Gaussian, autocorrelated, and so on).

I've been working on adding support for a (semi-proprietary) extension for PowerPC called "Paired-Singles". It's a SIMD instruction set supporting various operations on a vector of 2 32-bit floating point numbers. The Extension is found in the PowerPC 750CL, modified variants of it are used in the Nintendo GameCube (Gekko), the Nintendo Wii (Broadway) and the Nintendo Wii U
