similar to: Problem with polygon vertices

I am a new user of the R spatstat package and am having problems creating a polygonal observation window with owin(). Code follows: library("maps") library ("sp")` library("spatstat") mass.map <- map("state", "massachusetts:main", fill=T) # This returns a data frame includding x and y components that form a polygon of massachusetts mainland`

Dear R list, I'm trying to create an object of class "owin" (observation window) in the package spatstat from GIS mapping data. Here's an example of my problem. Everything goes well until the last line of code. I get the error message shown at the bottom: library(spatstat) library(sp) library(maptools) con <- url("http://gadm.org/data/rda/CHE_adm1.RData") class(con)

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

Dear all, I am currently working with the spatstat package, using windows and pixel images. First: My aim is to transform a shapefile (see attached) into a pixel image. My idea is to start transforming the shapefile into a Spatial Polygon file: x <- readShapeSpatial("200001441.shp") y <- as(x, "SpatialPolygons") z <- as.owin(y) Given z, I want to identify each

Hello All, I'm running Samba 3.0.24 as PDC and file server on Gentoo Linux, AMD64, 2.6.19 kernel, 100MBit/s network, and experience quite slow file transfers from Samba to WinXP SP2 clients: the speed is varying, but is about 1-2Mb/s at best. I spent quite some time investigating the issue, here are the intermediate results: 1) This happens only when transferring _from_ _Samba_ to

I have a list of bounds for a series of polygons. I do understand the formula to determine whether point i is within polygon X (X[x1] < i[x] & X[x2] > i[x] & X[y1] < i[y] & X[y2] > i[y]), and I can apply this throughout the dataset. However, this naive algorithm doesn't scale very well. The data set contains 10,000 points consisting of (n,e) pairs where I'm

In converting some older code: ## builds an OWIN to generate a set of points on a grid within the OWIN object: bdry <- read.shape( "../../data/boundary.shp" ) outline.verts <- bdry$Shapes[[2]]$verts[1:bdry$Shapes[[2]]$Pstart[2],] outline.order <- nrow( outline.verts ) : 2 bdry.poly <- vector( 2, mode="list" ) bdry.poly[[1]] <- list(

Hi. I'm having trouble with nut-2.0.3 on a linux kernel 2.4.32 machine and a MGE Evolution 3000. The problem is that I'm getting the following message, repeatidly, on dmesg: usbdevfs: usb_submit_urb returned -22 (-22 means -EINVAL) I traced the problem with newhidups -DDDDDD auto and found out that the -22 error appears in a line "none (-22)" of the output as: ----------

Hello, I am using the following code to create ppp files from csv data and map shape files, but I am getting some errors which I have been unable to fix by searching them online: library(spatstat) library(maps) library(maptools) NYC2<-readShapePoly("nybb.shp") # this is a map of the NYC boroughs without waterways and no census tract divisions (but it does include lines separating

Dear Community I am at my wits end and seek advice. My wish is to plot coordinates (x,y in WGS84_UMTS for the ones interested) of sampling points. This I can do by the standard spatstat prodcedure via owin. I then try to add an image, which is a map/satellite photo in the background. Firstly Problem: With the current code, I can not get the edges of the image to match the boarders of the plot

I talked to Tripp Lite Technical support. Their policy is that they only support Fedora and SUSE. There is no one there that could help with Ubuntu or NUT issues. The only answer they could give me was to port the rpm files to Ubuntu and use them. This is way beyond my experience level. I will go to the local electronics store and buy a cheap USB 2 hub to see if that works. I will post the

Dear users, I am trying to export polygons from Arcmap into Spatstat to run some simulations using functions available in Spatstat package. One particular area to be exported is formed by a number of polygons defining the external boundaries of the area (as a groups of islands) and a number of polygons inside the previous ones, as ?holes? not to be considered as part of the area. I have

Barry, I have had success with NUT on Debian and an EATON 5E2000IUSB-AU 5E 2000VA/1200W UPS With 3 x OUTLETS which I believe is good value. I would believe the the EATON ?5E 1500VA/900W UPS With 3 x OUTLETS would work just as well. The 1500VA also uses the same batteries as the 2000VA so I would believe it would run its raited load longer than 2000VA. My eight drive RAID driver uses less that

Dear R users, I wish to run spatial point pattern analysis (e.g. pair correlation function, mark correlation function) for which I need to create an observation window (window=owin) from which the spatial analysis is generated. The command I used to create this observation window as follows: X1<- ppp(x, y, window=owin(c(80.58,144.96),c(101.06,165.13)),

Irritating quirkyness: we have a bunch of videocams. To use, we use gspca. Usually, on an upgrade, I just go into the gspca directory (which appears, from their website, to have not been updated since '07), make clean, make, make install. Having gone up to 5.5, did the same. What's happening now is that it works, delivers the mpgs... but dumps errors in the logs: <snip> kernel:

Greetings; Nut pull & build from about two weeks ago, 2.4.3 I believe. Belkin UPS. I have everything working but a proper shutdown of upsd when I reboot, it hangs there and needs the hdwe reset button to reset it. That may be related to my finding more than 1 K##upsd and more than one K##upsmon, in /etc/rc5.d and which I have now nuked. However, while its working well enough to monitor,

Hi all, I suppose this is a very simple question, but as I've lost already a bit of time with it, without being able to get what I wanted, I'm addressing the question to the group in the hope someone can help me.
