Dear all, I got point data of trees. I was wondering if anybody has experience in searching the neighbors within a specified distance efficiently. X Y Z 99 34 65 98 35 29 98 34 28 99 33 33 98 32 23 99 33 21 99 33 22 99 32 24 99 30 23 ... What I want to do is : searching for the neighbors with a distance R for each tree & the neighbor must have a bigger Z.

On upgrading my F28 to F29, I've found that R-core and a number of R packages: R-evaluate R-glue R-highr R-knitr R-magrittr R-markdown R-mime R-stringi R-stringr R-yaml are installed, although I only ever install R from source and always keep my Rs locally. So I don't use Fedora R rpms, but these were installed without my command. Something in texlive is doing this. A remedy is to

Hi, I used .C to call the C functions inside R. Everything works fine on the linux sever. I installed cygwin on my windows xp x64 platform and used rcmd shlib xxx.c to compile. Everything works fine till now and xxx.dll is generated. But when I use dyn.load("xxx.dll") in R, it will open another R window and the original R window becomes "Not responding", nothing loaded in

Dear all, I have found some serious bugs in the knnFinder package (which supports data structures and algorithms for both exact and approximate nearest neighbor searching in arbitrarily high dimensions) that may trigger segmentation faults. I have fixed them but I had troubles to contact its maintainer Samuel E. Kemp (previously with the University of Glamorgan, UK). Do someone know where I

Hello. I'm pretty much new to R and I'm trying to produce some figures. It seems to me, that R has some asynchronous way of plotting figures. When I run this code: #constructs the semivariogram of SC1929 vgm1 <- variogram(SC1929~1,~U+V,puerto.map$att.data) # trying to make new plot dev.set(which=dev.next()) plot(vgm1) title(main="Semivariogram",font.main=4)

Hi, i created a graph with heatmap(sma) function: heatmap(dataHeat(x)) and I wish to change the gradation of colors from blue to red, how could i do? Using "heatmap(dataHeat(x), col=c(2,4))" i will use only 2 colors without gradation. Ty so much Andrea

Hi, I have no experience with R and I'm finding the manuals a bit obtuse and written as if I already understood R. I'm trying to import a csv file from a floppy and it's not working. The code I'm using is read.table("F:\GEORGIA\species_richness\SR_use.csv", sep=",", header = TRUE, row.names = 1) I'm assuming that this command is case sensitive so

Hello: I can't install the ' rgdal ' package in R and ' GDAL ' on CentOS 7 (ELGIS repo added). Is there any solution? Thanks -- Manuel Pizarro EBD-CSIC

Dear all, I would like to produce a map with information about the patenting activity in German districts, by coloring districts with different degrees of patenting activity in different colors. I work with the packages maptools, maps and spdep. The map data is read from an external .shp file (+ the corresponding .shx and .dbf files). Plotting a map with the IDs or the patenting indicator itself

I've run into a problem that I hope has an obvious solution. The sp package uses S4 classes and has a NAMESPACE, and when installed without package versions, runs OK, passes R CMD check, and so on. A user reported that he installed it --with-package-versions, and that from then on it would fail at first use of a class defined in the package. I've reconstructed the problem in a

Hi, I'd like to read a shapefile into a Map object. This is exactly what read.shape{maptools} is suppoed to do, according to the documentation I found in the link below. However, this doesn't seem to work library(maptools)x <- read.shape(system.file("shapes/sids.shp", package="maptools")[1])Error: could not find function "read.shape" I haven't

I'm hoping someone can help me. I have downloaded the proj4R.zip and under my version of R (2.3.1) I install the package from local zip file. This worked great. I then type library(proj4R) to load the library and I get the error: Error in library(proj4R) : 'proj4R' is not a valid package -- installed < 2.0.0? I have read through the install documentation and have downloaded and

Dear List, quantile(x) function allows to obtain specified quantiles of a vector of observations x. Is there an analogous function to compute quantiles in the case one have the vector of the observations x and the correspondent vector f of relative frequencies ?
