Re ading and Creating Shape Files
Hello R Community, I have imported a dataset which contain X Y coordinates and would like to recreate a shape file after some data analysis. What i have done is to import some taxlot data and join them based on some criteria. I want to check to see how well the joining went by reviewing the results in GIS. A couple things. I cant seem to import a shape file correctly using the maptools

liebert esp2 new version + crest factor
Hello, 1) I'm planning on adding lots of measurements to the driver liebert-esp2 + correct support for 3-phase systems. Should I make a large patch based on the last svn head or send you the whole file? Multiple patches per change are probably not practical in this case. 2) in http://www.networkupstools.org/doc/2.2.0/new-names.html there is no crest factor variable. Crest factor is very

How to fit a line through the "Mountain crest", i.e., through the highest density of points - in a "loess-like" fashion.
Hi, I'm trying to normalize data by fitting a line through the highest density of points (in a 2D plot). In other words, if you visualize the data as a density plot, the fit I'm trying to achieve is the line that goes through the "crest" of the mountain. This is similar yet different to what LOESS does. I've been using loess before, but it does not exactly that as it takes

RGDAL OGRwrite question
I have a quick question: It appears that in rgdal v0.7-12 (R version 2.15.1, OSX 10.6.8) writeOGR will not write a shapefile the the current directory. Is this correct? An earlier version of rgdal must have allowed this because I have a older script that used to work, but doesn't now. So, as an example, here is what I get today: > shape = readOGR('.',

write geotiff with projection - RGDAL package
Hi, Doing more search i've discovered package RGDAL that can write a geotiff file with projection. I saved a geotiff file in UTM projection and if i read the file back in R and check the projection seems that everything is OK. But if i load the file in ArcGIS (ESRI product) i get the warning that the file is missing spatial reference so it cannot be projected, but it is displayed correctly.

Trying to rename spatial pts data frame slot that isn't a slot()
Dear List, I am analyzing the home range area of fish and seem to have lost the individuals ID names during my manipulations, and can't find out how to rename them. I calculated the MCP of the fish using mcp() in Adehabitat. MCP's were converted to spatial points data frame and exported to qGIS for manipulations. At this point the ID names were lost. I brought the manipulated

How to improve the robustness of "loess"? - example included.
Hi, I posted a message earlier entitled "How to fit a line through the "Mountain crest" ..." I figured loess is probably the best way, but it seems that the problem is the robustness of the fit. Below I paste an example to illustrate the problem: tmp=rnorm(2000) X.background = 5+tmp; Y.background = 5+ (10*tmp+rnorm(2000)) X.specific = 3.5+3*runif(1000);

Bubble plot on shapefile - projection issues?
Dear R help list, ? I am working on some data from a study on the habitat use and movement patterns of fish using a marine protected area in Hawaii.? We have a number of acoustic receivers in a MPA, and any time a tagged fish passes within range it records the date and time of detection.? I am trying to make bubble plots?showing the number of detections for each fish at each receiver.? I have been

How can I save plot()/points() using SHP files into KML format?
Hi, I am new to R and am a very basic user. I'm importing SHP files, adding plots of random locations within my polygon (these files have GPS data), and then want to save these plots (intact with added points) as KML files to look at in GoogleEarth (or possibly as SHP files which I can then convert into KML). This is as far as I've gotten (code below) and am lost as to next steps, Any

simplify shapefile and save output
I have several large shapefiles that I need to use to draw a map. I want to simplify the files and then save the output so that I can use them again. The methods that I have tried do not allow me to save the simplified output as a shapefile. I have tried: thinnedSpatialPoly in the package maptools, but I understand that you cannot save the output as a shapefile because the topographical features

Convert tileplot's trellis to shapefile/ Add values to voronoi polygon

I was able to do it in tileplot(latticeExtra) like the ones attached, and with the following commands: xy=list(x=x2$X, y=x2$Y) xy$street_cle <- x2$street_cle tileplot(street_cle~ x*y, xy) But this is a trellis.

[spatstat] Convert shapefile to 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
