Using R 2.5.1 on Windows XP Professional, and PBSmapping package version 2.51, I have encountered some behavior which puzzles me. I am including the package's listed maintainer on this email but also seek the thoughts of the R-help community. I have a set of EventData, which I want to plot as points, and to color the points according to som...

Hi folks, I've been using 'PBSmapping' to make a map of Europe with some labels. I've been using the 'worldLL' PolyData, as my computer is too slow to make my own from the GSHHS files. The only problem is this PolyData does not seem to include Ireland. I have no idea why this should be so, other European islands su...

Hi, Is there a way, preferably with R, to read shapefiles and transform them in a format that I could then use with package PBSmapping? I have been able to read such files into R with maptools' read.shape and plot it with plot.Map, but I'd like to bring the data to PBSmapping and plot from there. I also looked at the package shapefile, but it does not seem to do what I want either. Sincerely, Denis Chabot

Dear List, I am trying to use the PBSmapping package to import and plot the shoreline of Hawaii. I am having problems importing and plotting the specific regions that I would like to plot. Specifically, I can't get it to import the range of x variables that I would like. I think my problem is with a variable called xoff, but I have...

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 abl...

Hola, Estoy tratando de sobreponer un mapa sobre otro, uno que sirva de ?background? y otro con datos. Mi primer intento lo hice usando el paquete PBSmapping. Aquí lo que hice: library(PBSmapping) estados <- importShapefile(?Entidades_2013.shp") #Aquí cargamos las entidades federativas (32 entidades) zonas <- importShapefile(?zm.shp?) #Aquí cargamos las zonas metropolitanas del país (345 municipios) plotPolys(estados, xlab=?Longitud?, y...

Hello, List, I am a new user of the R project, and I need some help in plotting a legend. I am using the PBSmapping library to plot map of Ohio and heat color it with the count of employees in each county. As a guide, I am using "Data Mashups in R." I am able to plot the map with the colors; however, I would like to put a legend with a single box full of these colors, but only show the max and the...

Dear all: I have a shapefile in UTM coordinate system and I would like to transform it to Lat/Log coordinates (WSG84). The package PBSmapping contains function convUL to transform between the two coordinate systems when data is in the form of a data frame with attributes specifying the coordinate system. However, when shapefiles are imported using function read.shape (package maptools), a list instead of a data frame is generated. I...

Hi, is there a function in R to convert data read with read.shape and which is originally in UTM coordinates into longitude / latitude coordinates? I found the convUL() function from the PBSmapping package but I have no idea how I could apply that to the read.shape object. Many thanks, Werner __________________________________________________ Do sragenden Schutz gegen Massenmails. http://mail.yahoo.com

...d like to know which function is the most efficient in finding convex hull of points in 3(or 2)-dimensional case? Functions for finding convex hull is the following: convex.hull (tripack), chull (grDevices), in.chull (sgeostat), convhulln (geometry), convexhull.xy (spatstat), calcConvexHull (PBSmapping). I also would like to know if there is a function that can be used for finding convex hull in multi-dimensional case, that is more than 3- dimension. Thank you in advance.

Hi R helpers, I tried to convert a list of LatLong coordinates (in DD format) into UTM zone 11 NAD 27. I first tried this from PBSmapping: library(PBSmapping) LatLong<-cbind(c(56.85359, 56.85478),c(-118.4109, -118.4035)) colnames(LatLong)<-c("X","Y") attr(LatLong, "projection") <- "UTM" attr(LatLong, "zone") <- 11 UTM<-convUL(LatLong) #and that's what I get...

Dear all, I am new to R and even newer to mapping with R. I have installed PBSMapping, maptools and maps, and I am struggling to produce a map of fish abundance in the Grand Banks. I have tried several approaches to plot the bathymetry in my study area: 1) download the data from http://topex.ucsd.edu/cgi-bin/get_data.cgi (42N46N313W307W) To start with, the map I get is...

...de,OriginLatitude) and (DestinationLongitude,DestinationLatititude), e.g. a flow map between the ports. At some point, I may wish to add an underlay base map (say counties in the US), but that is not critical at this time. There seem to be many packages in R that deal with spatial data (sp, maps, PBSMapping, etc.), but it is unclear to me which one would work best for this application. Any advice gratefully appreciated. R. Males Cincinnati, Ohio, USA

I have some disconnected boundary data from a finite element ocean model and I'd like to make a plot. Maptools looks promising, but since my data is not in a shapefile or a map, I'm unclear on what the best way to approach the problem. >geom[1:10,] lon lat depth 1 -75.42481 35.58192 16.172 2 -75.40726 35.58567 18.045 3 -75.41351 35.60312 17.333 4 -75.38888 35.58959

...; in library(maptools). Now I need to plot a set of points in that region (my.dataframe, with X and Y geographic coordinates), which have been read using GPS in Longitud-Latitud form (using WGS84 system), so I first need to convert these Longitud-Latitud data into UTM data. To do so, I use package PBSmapping: attr(my.dataframe, "projection") <-"LL" attr(my.dataframe, "zone") <- 30 my.dataframe<-as.PolySet(my.dataframe) my.dataframeUL<-convUL(my.dataframe) obtaining the UTM coordinates. But when I plot them in the polygon region, points seem to be badly l...
