Hi R-help I am trying to mask the ocean from an image plot I have made. Here is some example code: library(mapdata) image(x=110:155, y =-40:-10, z = outer(1:45, 1:30, "+"), xlab = "lon", ylab = "lat") outline <- map("worldHires", plot=FALSE) # returns a list of x/y coords xrange <- range(outline$x, na.rm=TRUE) # get bounding box yrange

Does anyone have any experience plotting complex polygons on a scatterplot3d display? I would like to present some spatially binned data in a 3-d type plot with background polygons (i.e.. a filled coastline map). I can get the coastline onto the plot window as a line type but cannot figure out how to fill the shape. I'm certain it may be possible but might require a bit of digging

dear all: Im trying to obtain maps on R, under mapdata library, but I cannot define the labels. Here is an example: library(mapdata) map("worldHires", c("portugal","spain"),ylim=c(34,46),xlim=c(-14,3.5)) axis(1,at=seq(-12,3,3)) axis(2) when I try the parameter xlab or ylab in axis, i get: parameter "ylab" couldn't be set in high-level plot()

Dear all, I would like to employ a European map in a presentation. My idea was to use: library(mapdata) map("worldHires", c("Austria", "Switzerland", "Germany")) where I include all countries from my analysis as a vector of character strings like in the example above. Unfortunately, I was unable to specify the Baltic States (Latvia, Lithuania, Estonia) or

R users, In S, there was a function called usa() that would draw the map of the United States, plus it had other options for graphics. I have looked but I can't find the equivalent in R. Is there one? Thanks, Jason

Hello, The other day Justin Peter presented a mini program to plot a topographic map with an overlay of the worldHires. I seemed interesting so I checked the ETOPO5 site and find that there is a new file ETOPO1 with a 1 minute grid. I downloaded it and tried a similar procedure. Now the ETOPO1.gz is 1 Gb and the uncompressed file is 5 Gb. They do not fit into my laptop. I tried the following

Hello, I am trying to draw geographical maps with the maps package. However if I try to access the data following error occurs: > require(maps) > map() Fehler in zip.file.extract(file, "Rdata.zip") : 'destination' existiert nicht # Error in zip.file.extract(file, "Rdata.zip") : 'destination' does not exist > traceback() 4: zip.file.extract(file,

Hi R-Help, I would like to make filled contour maps of ocean data overlaid by costlines from the map package. I can draw the filled contours and the coastlines om the same plot, but the filled contour also covers part of the land. To get rid of that I tried to draw a filled coastline map on top of the filled contour, but the filled map only draws the closed contours - so most of the land is

I have just learned how to play with map, but something weird (or not) is happening. Suppose I want to draw a map of two countries (that have disconnected components), like Argentina and Brazil. If I command: library(maps) library(mapdata) map("worldHires", c("Argentina", "Brazil")) It works fine. However, if I want to _colour_ the interior:

Hola. Tengo algún tipo de problema con las tildes, a la hora de trabajar en R o en RStudio, que no sé resolver. Intentando reproducir en dos PCs distintos, ambos con Windows 7, uno de los últimos ejercicios que ha publicado Carlos Gil Bellosta en su blog ( https://www.datanalytics.com/2016/06/20/6602-767-km-alrededor-de-espana-para-visitar-todas-sus-capitales-de-provincia/), me ocurre que al

Dear Ms and Mr R, I am seeking a visually appealing presentation of 3 variables (~30 datapoints) that are correlated and that should to into the same direction. The objective is to show that they do go in the same direction and what differences there might be while also giving an idea of the values of the variables. I had done this with simple bargraphs for 6 datapoints in the past, but for

Hello everybody, I'm an absolute newbe in R, so please be gentle to me. I am looking for a german map in the package maps by Becker and Wilks. After that I want to draw the German cities from world.cities of this package in the map and want to draw further a line from Berlin to Munich. Has anybody an idea? Thank you so much and sorry for the question! Best regards from Berlin, Maja!

Hola, Carlos. Pues, efectivamente, me ha ayudado. Sobre la utilización de la función geocode con ciudades con tilde, me dio Carlos Gil Bellosta anteriormente la idea de utilizar iconv para transformar la cadena de búsqueda a UTF-8, y yo lo utilicé para intentar transformar el output de html_table sin resultado: capitales <- read_html("

Hola, Carlos. A mí también me resulta raro, porque no me pasa siempre. Es un poco aleatorio. Imagino que habrá alguna razón, y que el código de la página estará relacionado, claro, pero no consigo averiguar a qué se debe. Además las pruebas que hago me dejan todavía más perplejo. Esto Encoding(capitales) me dice que el encoding es "unknow", pero luego esto validUTF8(capitales) me

Thanks Mike. My data has longitude and latitude coords and I used distAB {clim.pact} then mst {ape} to calculate my minimum spanning tree. The nodes are telecoms sites from all over Australia. My goal is to determine the minimum cost of linking them via cabling, and I'm starting by calculating the distance "as the crow flies", but will probably eventually need to calculate the

hello.. i am currently trying to use :through to attach two of my models together using geokit. for some reason, i am running into a problem: ArgumentError: Unknown key(s): as i have two models, one that is geocoded, and one that belongs to that model. the models look like: ,----[ employer.rb ] | class Employer < ActiveRecord::Base | acts_as_mappable | before_validation_on_create

Hi list, Well, this time I’ve a doubt with mapping generation. I was already able to read and plot shapefiles, plot point on this map. All this without any problems, but now I want to do something that I think, only Golden Software Surfer is capable of. I would like to plot a kriging result on the existing map (map script below). Well I looked for on the net, but I was not able to be sure of

Does anyone have suggestions about how to produce a map of British Colonial America 1775? At that time, Great Britain had 26 colonies in the Americas, including Bermuda, several Caribbean islands, "Quebec" (extending then almost to New Orleans), Nova Scotia, Newfoundland, Belize, and the 13 that declared independence in 1776. I've reviewed the "map"

Hey, Does anybody know of a good Geocode library for Ruby, similar to Perl''s Geocode::Postal, that i could use in my rail app? I need to do some "within 5 miles" calculations of zipcodes and i dont have a nice ruby (or gem) utility to do it. any help would be appreciated. thanks adam _______________________________________________ Rails mailing list
