Hi! Im new to R and I need to interpolate a shapefile using kriging. I've been able to plot/read the shapefile using the package maptools or rgdal. I've searched the internet for sample codes but most of the kriging codes that I've found done in R is done using txtfiles or CSVs.  An example could be of great help. Thanks.

Hi, I would know how to plot two variograms on a same graph. I can plot one by one but I would draw both on the same one. Is it possible? Do i need any special package? Thanks! Cordialement Damien Landais

Hello, I often find myself writing code like : if( require( "foo" ) && compareVersion( packageDescription( "foo")[["Version"]], "2.1" ) < 0 ){ # code that uses version 2.1 of foo } else { stop( "could not load version >= 2.1 of foo" ) } Would it make sense to include something like this in require, library, etc ... require(

Hi, I guess the backslash should not be used as the separator for strsplit() in compareVersion(), because the period in [.] is no longer a metacharacter (no need to "escape" it using a backslash): https://github.com/wch/r-source/blob/trunk/src/library/utils/R/packages.R#L866-L867 > compareVersion function (a, b) { .... a <- as.integer(strsplit(a, "[\\.-]")[[1L]])

Hello I have been trying to install gstat on university's unix based system ( i am not familiar with many technical aspects of installation) but i am getting a particular error which i could not find a solution to online. Here is what the technical support guy mailed me back, i am sure someone who understands the technicalities can explain me this procedure in a more lucid way. * **Technical

Hi, I am looking for a way to find out the version information of installed R packages. ex: >library(affy) >SOME_COMMAND_FOR_VERSION(affy) I know I can do either getRversion() or R.Version() could give me the version of R. I assume there must be a way for me to get version information for the add-on paclages,right? Thanks! Yupu

When loading a package with library(APkg) or require(APkg) I would like to make sure that (1) the correct version of [R] is installed. If not an informative error message should be given. I would also like to make sure that (2) another required package which is loaded from within the APkg package (by require(OtherPkg)) is of a certain version or later. First of all, I believe that the check

Hi, On Windows, with last R-devel tarball (r40647) from ftp://ftp.stat.math.ethz.ch/Software/R/R-devel_2007-02-04.tar.gz I get the following build error: E:\biocbld\bbs-2.0-bioc\R\src\gnuwin32> make ... ... ---------- Making package utils ------------ adding build stamp to DESCRIPTION installing NAMESPACE file and metadata installing R files Error in namespaceExport(ns, exports) :

Dear All, I run following code to estimate the blocks using cokriging ( my data set has more than 50,000 data points). All the things run finely but Once I run the predict.gstat function it gave the error message - "memory.c", line 58: can't allocate memory in function m_get(). I run this code on LINUX sever but result is same. Would any one please be able to give a solution for

I'm new to R and I'm working on point shapefiles. Is there a way that you could interpolate a shapefile via kriging in R using an attribute? All examples on the internet are using txt files and CSVs. Thanks a lot. [[alternative HTML version deleted]]

Hi all, We know old.packages() can check for updates of add-on packages, but is there a way to check updates of R itself? "go to R homepage" is a way, of course, but I hope this can be done by R. I'm not sure about the "reliable" place to check; here is a simple example to check from one of the CRAN webpages (kind of nasty approach...): x =

Dear R developers, I asked this question in r-help list but have not got a definite solution yet, and I think it might be more appropriate to ask developers or CRAN maintainers directly. Many software packages often have a menu item like "Check for updates" under the "Help" menu, e.g. Filezilla and Firefox, and I believe it is also necessary for R (at least for R GUI under

Hello, I'm interested in doing Bayesian kriging using R. I see that the package geoR has a function that will allow one to do this (krige.bayes). However, my data are not in the form of points, but rather they are blocks that represent spatial averages (i.e., the number of fishing hooks per month in a given lat x long square). I am therefore interested in treating the data as

Hi, there was a memory improvement done in R going from R 3.3.3 to R 3.4.0 when it comes to comparing an integer 'x' an double 'y' (either may be scalar or vector). For example, in R 3.3.3, I get: > getRversion() [1] '3.3.3' > x <- integer(1000) > y <- double(1000) > profmem::profmem(z <- (x < y)) Rprofmem memory profiling of: z <- (x < y)

I only recently discovered options("available_packages_filters" = list(add = TRUE, "license/FOSS")) [cf. help("available.packages", package="utils") in R 2.10.0 or later] which goes nicely with my options("checkPackageLicense" = TRUE) [new in R 2.11]. But now I want to purge my library of packages I would not have installed had I known about

Hei, I have two spatial datasets Sa and Sb, both with lat-lon coordinates and from same geographic area, but from different localities within the area (independent samples). Sa is biotoc data, Sb is some environmental parameter (fertility). I 'know' that Sb affects Sa, but wonder on which scale. I tried different interpolations by creating different grids of Sb (e.g. 20x20 and 100x100

Hi- I am trying to find a way to diffuse GIS data on a European map. I have a dataset consisting of particular locations scattered across Europe, along with magnitude and value information. I can plot these as discrete points with something like the following: "geocode" is a dataframe with four columns: LAT; LONG; MAGNITUDE;VALUE. library(maps) library(mapdata)

This is an RFC / announcement related to the 2nd part of PR#16885 https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16885 about complex NA's. The (somewhat rare) incompatibility in R's 3.3.0 match() behavior for the case of complex numbers with NA & NaN's {which has been fixed for R 3.3.0 patched in the mean time} triggered some more comprehensive "research". I

That, for example, complex(real=NaN) and complex(imaginary=NaN) are regarded as equal makes it possible that length(unique(as.character(x))) > length(unique(x)) (current code of function 'factor' doesn't expect it). Yes, an argument for the behavior is that NA and NaN are of one kind. On my system, using 32-bit R for Windows from binary from CRAN, the result of sapply(z, match,
