Sorry, I did not make my question clear. Since I have a point theme with many points, some of them may clump together. the problems here are: 1. how to find clumps in a point theme? 2. the convex-hull extension I found only deal with all the points in a theme at each time? how to make each convex hull around each point clump automatically? Thanks. Xiaohua On 5/12/06, Bob Booth <bbooth

Hi R users, Hope the question is not too simple: How to use a for loop to generate two lists as below: testlist <- list(test1, test2, ..., test1000) stringlist <- list("test1","test2",...,"test1000") Thanks Xiaohua

Hi R users, Sorry for a simple question: I found different people use different i in set.seed(i), are there any rules to choose an i or one can choose as he likes? Thanks Xiaohua

Hi R users, I use plot.circular(rad, stack=T,bins=4) and could just obtain the four stacks in the directions of 45, 135, 225 and 315 degrees. But I want them in 0, 90, 180 and 270 degrees. Is there any parameter or any other function to make it?

Hi All, Does anyone know how to compare the means of several circular-data samplings? Any related websites, references and softwares? Thanks Xiaohua -- Xiaohua Dai, Dr. [[alternative HTML version deleted]]

Hi R-users: Yesterday I ran a R code for 9 hours and it did not show any sign to stop. Then I interrupted it and found it had completed 82.5%. This morning I decided to wait for another 11 hours to see what will happen. Wait a minute, I heard that transforming data.frame to matrix will make R code faster. Then I made the modification in my R code. Oooh, the new code finished within 30 minutes!!

This is slightly off-topic but I would be interested in whether anyone has succeeded in creating a filter expression for Google's gmail system that will select messages sent through the R-help and R-devel lists. It seems as if it should be easy to select on '[R]' or '[Rd]' in the subject line but I haven't been able to work out the exact syntax that would do this and not

Hi R-profs, Maybe my question is a little off topic. Could any one tell me how to calculate a linear-circular correlation coefficient and its p-values? I had a quick look at circular and CircStats packages and did not find the related function. Thanks for any kindly help.

Dear Dr. Bivand and R-users, I have a 5 by 5 grid, say, location[1:5,1:5], and I want to know the indices of 8 neighbours of each cell. For example, for location[2,2], its neighbour coordinates are [1,1:3], [2,1], [2,3] and [3,1:3]. Sometimes I also need to remove edge effects (torus = TRUE). I have tried "cell2nb" function in your spdep package. Here's my example: > neigh

Hi Gurus! I have a job that is to get randomly samples from point-based GIS data (sp called shape GIS files) under the total sum resctricted. For example, I would like to take random smaples under the 1000 persons in each city. The randomly sampled persons should not be over 1000 any case.

Is there any routine to generate for one vector matrix. If I have X I want to generate start from zero to maximum value each vector. For example, I have a vector x = (4,2,3,1,4) I want to generate n=6 times, for 4, start 0 to 4, then 2 start 0 to 2, ect. The result something like this: generate(x,n=6) 1,1,2,1,4 1,2,3,0,3 4,0,1,1,1 3,1,0,1,4 0,0,3,0,0 4,1,3,0,4 Could anyone help me. Thanks.

Hello, is there a package in R that would allow map drawing: coastlines, country/state boundaries, maybe topography, rivers etc? Thanks for any guidance, Mark

I've noticed that I get a warning message every time a package masks some functions from Hmisc. The warning message says : Warning message: In identical(get(., i), get(., lib.pos)) : ignoring non-pairlist attributes This happens with eg: library(plyr) library(xtable) I think I've seen this passing by before, but I'm not sure any more. Just thought I'd mention it. Cheers Joris

Dear all I am happy that summary.default() no longer rounds since R 3.4.0. However, in R 3.4.0, in a few cases, print.summaryDefault() rounds the mean value (and the median value) differently on my GNU/Linux machine and on my colleague's MS-Windows machine. Here is a small (simplified) reproducible example: R> a <- 1234568.01 + c(0:1) R> summary(a) Output on MS-Windows (expected

I am hitting an odd message "Error in FUN(newX[, i], ...) : all arguments must have the same length". I can't supply the data as it's a huge data frame but I think this has enough diagnostic information to show the issue. I am sure I am missing something obvious. I've put some extra comments in but otherwise this is cut and pasted from Rstudio. ### I wanted a table of the
