A while ago our institute was approached by a large company, say XXX, who asked whether we would like to become an Xxx development center, as we are active in the same area. After some negotation we did, believing there will be mutual benefits. Some time later, after putting up the Xxx development center logo on the institute home page, my feeling grew that we are also, and probably to a larger

Suppose I'm author of a package on which quite a few other packages depend. When I submit to CRAN, I run R CMD check on it, Kurt does that too, and if things work out fine, it is accepted. When one or more of the packages that depend on it break because of my changes, however, hell breaks loose. I would like to extend my testing (currently: R CMD check pkg) to running R CMD check on all

List, In order to get rid of some old, unreadable S3 code in package sp, I'm trying to rewrite things using S4 methods. Somewhere I fail, and I cannot sort out why. In order to isolate the problem, I created two functions, doNothing<- and dosth, and both should do nothing. The issue is that in most cases they do nothing, but in some cases dosth(obj) changes the class of obj and breaks with

When running a = runif(10) class(a) = "foo" Math.foo = function(x, ...) { NextMethod(.Generic) } signif(a, 3) cumsum(a) I don't understand why cumsum strips the class, but signif does not. Both claim in the documentation that "These are generic functions: methods can be defined for them individually or via the ?Math? group generic." -- Edzer Pebesma Institute for

Hello- Does anyone know if R can read in ESRI file geodatabase feature classes, directly from the file geodatabase? I currently have to export the data out of Arc, to a csv file, then read the csv file. I'd like to bypass this step and read directly from the file geodatabase. Thanks for your help. -al

Dear all, I'm trying to connect to an MSAccess database (ArcGIS personal geodatabase). I keep getting an error about the channel when using sqlQuery(). However, sqlTables() does not complain about the channel and lists all tables in the database. If I try sqlFetch(), then R crashes. I'm happy to hear suggestions on how to solve this. Best regards, Thierry > MDB <-

Thanks, Paul -- setting the ~/.fonts.conf file the way ?X11 describes it under the section you pointed to resolved the problem for me, on ubuntu.

Hi All! As a new useR, I am currently working in R 2.5.1 to produce Ripley's L (the linear version of Ripley's K) for a spatial point dataset (originally a ESRI shapefile). I have coerced the data to a ppp object (because I was originally using 'kest' in the spstat package to produced Ripley's K) but I need to convert my spatial data to a spp object to be able to use

Hi Thanks for that, but I still cannot confirm on ... sudo docker run -v $(pwd):/home/work/ -w /home/work --rm -ti rocker/r-ver:3.5.1 Could you please read the comments within the "Cairo Fonts" section of the ?X11 help page, in case that offers some explanation.

This warning message is on my to-look-at list; I agree that sometimes it's obviously possible for the system to get the information if it tries hard enough. The message means what it says: Class information in a session includes the currently loaded subclasses of a particular class. Not critical but sometimes useful. In this case, (as I understand it without having looked recently), the

Thanks to Edzer and Roger, I can now plot with increased font sizes. However, jpeg still does not reproduce these, nor does it show up in high quality. What I would like to do is produce some highresolution jpegs. Any help would be appreciated Thanx Herry R2.4 on Mandriva 10.2 linux.

I'm trying to find an R package that will smooth a line with the "polynomial approximation with exponential kernel" or "PAEK" algorithm that is used in ESRI's ArcGIS software. I have a copy of the original paper that provides the algorithm, but I'm not confident in how to code it. The algorithm will smooth a polyline's vertices at a user specified distance

We're happy to announce the CRAN release of "sp", an R package which has new-style classes and methods for spatial data, version 0.7-9. Spatial data types that sp implements are: points, grids, lines, and polygons (i.e., rings) optionally with holes. Methods include + the usual print, summary, plot, [, [[, $, ... + coercion between types (e.g. points and grids, matrices,

On R 2.15.2 and ArcGIS 9.3.1, it works for me in ArcCatalog but you have to follow the particulars here: http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?TopicName=Accessing_delimited_text_file_data For example: write.table(test, '***.tab', sep = '\t', row.names = F) The extension .tab and sep = '\t' are required for text files. Didn't test row.names=T but I

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 I am seeking to understand why the methods package (to be specific `methods:::.findOrCopyClass` when called by `setIs` when called by `setClass`) emits a warning message such as ` class "SpatialLinesNULL" is defined (with package slot 'rgeos') but no metadata object found to revise subclass information---not exported?

Dear All I would really appreciate some help with a script which a colleague wrote for me (attached), but I am having problems running (and have not been able to contact my colleague). The script is designed to compare the area of suitable habitat in binary projections of a large number of species current and future distributions, and create an excel file detailing the total area suitable in the
