Pattern matching - how to ignore numbers after 10 digits
All: Yesterday I discovered something interesting. I dialed 1800ANCESTRY from the asterisk system I am testing and got the number doesn't exist message. I then dialed the same number from our old system and it went through. I realized that the "Y" in ancestry made the number too long, and went back to my dialplan. How do I ignore numbers that are too long? Obviously,

A matter of context
All: I've starting building an asterisk system for our company, which has about 60 users. I am new to asterisk, so thank you for your patience.

Drawing maps in R?
What tools and documentation exist for producing maps and working with polygon and polylist objects in R beyond the following: * Packages maps, mapproj, maptools, and mapdata. * Becker and Wilks (1993, 1995), listed as references in the documentation on the "map" function. Thanks, Spencer Graves

Teaching R in 40 minutes. What should be included?
If _you_ were asked to give a 40 minute dog and pony show about R for a group of scientists ranging from physicists to geographers what would you put in? These people want to know what R can do. I'm thinking about something like: A. Overview B. data structures C. arithmetic and manipulation D. reading data E. linear models using glm F. graphics G. programming H. other tricks like rpart or

writing polygons/segments to shapefiles (.shp) or other A rcGIS compatible file
The main limitation of the shapefiles package that I put together is that it does not create shapefiles from R objects - rather it only writes shapefiles that have been read into R and manipulated within the constraints of the existing file structure. By this I mean that for example you can change the coordinates of points and write them back out. Or you can add a bunch of blank columns in the

diffusing GIS data in maps
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)

having issues with shares
We recently migrated our install from an ancient fedora 11 install of samba and openldap to a centos 6.3 setup with its openldap and samba. The domain has been totally recreated from scratch as the person that did the previous setup has not been employed here in many years. After fighting with shares for a while we mostly got them fixed and working. However the biggest issue now is when our GIS

CentOS, PHP, Basic GIS
I have no experience with GIS whatsoever. I really know squat about it. I'm currently working on a project to plot locality data for wildlife on a map of Shasta County. This is for a new herpetological club that hopes to track strength of our local herp populations, since it seems evident that in the last 20 years we lost one species of frog and are close to losing another (probably less

Linking R to GIS
Dear All, Has anyone worked with linking R to both ArcView and MapInfo GIS systems? My desire is to capture object selection from GIS and pass to R and to return spatially based statistical model results from R to GIS. If both could simultaneously access the same data file this would be a bonus. My inclination is to put together some routines based on ODBC linking but thought I would seek like

How to sample x-y coordinates from GIS files
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.

envi clone in R
Hello all, Research Systems (www.rsinc.com) have developed and distributes the language IDL, and the GIS ENVI, written in IDL. To my oppinion, R language is superior, compared to IDL, in all aspects. However, ENVI is the rather convenient and feature rich tool. Is anyone aware about any work, dedicated to the creation of something, similar to the ENVI, but in R? Also, recently,

labelling plots with ancillary data in data.frame
Hi All, I am busy using R to do some regression modelling and have been using plot(x,y,"") to visualise my variables. I would now like to label my points using data stored in the data.frame used for the regression analysis. For example each of my data points is made up of a field measured forest volume value and a remotely sensed vegetation estimate (NDVI). Each point is an enumeration
