I am not sure a previous e-mail reached the list (no mail aknowledgement from R-boundle etc.). The question was how to write polygon or segment coordinates into a shapefile set or any other ArcGIS supported format. The library shapefiles seems to do something but the documentation is a bit beyond of my mind.... and I cannot get the meaning of the functions write**** and its application to the case

Hi Guys Thanks for this! As I am a beginner, I bet I'm running into some really basic problems. Using the example from the Map2poly function in maptools: try <- read.shape("euadmll.shp") mappolys <- Map2poly(try) # this produces 14 warnings() of the type: # 1: level 2 circularity at 62 in: .mtlbuild(.mtafters(r1), rD) # etc # 14: From next release, default hole handling

Dear All, In the moment i'm using the map and maptools package to read shapefiles and display the maps. I'm looking for the possibility to draw points (randomly positioned or positioned according to a grid) into the polygons instead of filling the polygons with colors. For example: a map (shapefile) with 10 countries, 15 points in the polygon of country A, 20 points in the

Greetings: I would like to kindly ask for a little help. The rough code is: #________________________________________________________ dat=data.frame(read.delim(file="all.txt", header = TRUE, sep = "\t", quote="\"", dec=".",na.strings = "NA")) nc=read.shape("astae.shp", dbf.data=TRUE, verbose=TRUE) mappolys=Map2poly(nc) submap

Dear R users, Probably, this is quite a simpe question, but I do not find the proper way to obtain want I need. To explain the problem, I constructed a simple example. Suppose I have the following function: try1<-function(x){ y<-x[1:2] z<-x[3:4] y[1]*(z[1]+z[2])+y[2]*(z[1]+z[2]) } This function will be part of a for loop. This is what I like to obtain for every k: if k=2

This involves looking at the value stored in %x at all predecessor points, which is a challenge because one of those

My sincerest apologies, as this is a very elementary problem, but I have searched through archives and FAQs and on the web, and I am at the end of my own resources. I need to do analysis of a spatial point process occuring with four counties, using spatstat. I've had no trouble importing the shapefiles, but I can't seem to figure out what I need to do in order to use the boundary as an

Is there a means to split a vector into its individual elements without going the brute-force route for arguments to a predefined function call? offred.rgb <- c(1, 0, 0) * 0.60; ## Brute force style offred.col <- rgb(offred.rgb[1], offred.rgb[2], offred.rgb[3], names = "offred") ## Desired style

I feel dirty. I have some graphs I'm building to communicate chargeback rates and service usage for our backup system here at the University of Florida. These come down to daily data points on a graph of number-of-bytes transferred and stored. Since we chargeback on the same basis (price per MB this, price per KB that) the same chart with a different scale can be used to communicate bytes

Hi, In another thread ("PBSmapping and shapefiles") I asked for an easy way to read "shapefiles" and transform them in data that PBSmapping could use. One person is exploring some ways of doing this, but it is possible I'll have to do this "manually". With package "maptools" I am able to extract the information I need from a shapefile but it is

Hi: Is there any function in R which can convert the long/lat to UTM(Universal Transverse Mercator)? There are quite a few converters on Internet. However, the interface is designed as input->output which I can not convert lots of locations at the same time. Another question is whether there is a function in R which can tell the time zone from the location's lat/long? Thank you!

Using the maptools function "map2poly" I have created a map/polylist object - a map of the Great Lakes. My goal is to passively plot additional data on this map. Unfortunately I am not able to change (distort) the relative scale of the axes for the map, and so the sample points do not line up correctly on the map. In the code below, notice that I have set the same axis ranges on each

Dear all, We are doing some research about the time series analysis of NDVI, and we found the NDVITS package which is a very great tool. Unfortunately when we run it, after TimeSeriesAnalysis it asks to enter "Village or Country". library("ndvits", lib.loc="/home/vahe/R/i686-pc-linux-gnu-library/2.15")

I executed the code in rstudio successfully: library("ndvits", lib.loc="/home/vahe/R/i686-pc-linux-gnu-library/2.15") ndvidirectory=paste(system.file("extdata/VITO_Mzimba", package="ndvits"), "/", sep="") region="Mzimba" Ystart=2004 Yend=2006 shape="SLP_Mzimba"

Hello list, I try to setup an asterisk-server with different SIP-Peers to PSTN. The Peer are working and configured in sip.conf: [peer1] type=peer host=10.10.10.1 [peer2] type=peer host=10.10.10.2 Now dialout is no problem. Extensions.conf says: exten => _0Z.,1,Dial(SIP/49${EXTEN:1}@peer1,30) But how can I setup a failure-route if the SIP-Proxy "peer1" ist not
