rworldmap

问题 I want to fill a map with some countries from UE, and then some continents like Asia and Africa, according to my variable prob2 values . This is my data map_d : state prob2 <chr> <dbl> Germany 0.6 Austria 2.9 Belgium 1.9 Bulgaria 0.6 Cyprus 0.0 Croatia 1.7 ... Other Asian 9.2 Other African 2.5 Other North American 10.7 Other Latin American 2.3 Other Oceania 5.0 Firstly I fill the countries of Europe, using this code: europ_map <- map_data("world", region = c( "Germany", "Austria", "Belgium",

问题 When I load the rworldmap package, it can not be loaded in R software (version: 3.0.3). The rworldmap package has been installed. Code: library(rworldmap) Wrong information appeared on the window as follows: " Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : there is no package called ‘fields’ Error: package or namespace load failed for ‘rworldmap’ " How to tackle it? Thanks for your attention. 回答1: Try this in R studio where Dependent packages are

问题 I would like to adjust the legend bar of rworldmap. mapCountryData(df, nameColumnToPlot="users", xlim=NA, ylim=NA, mapRegion="World", numCats=30, catMethod="pretty", addLegend=TRUE, mapTitle="map1", colourPalette=c("heat")) do.call(addMapLegend, c(mapParams, legendLabels="all", legendWidth=0.5, legendIntervals="data", legendMar=2)) I was able to generate the map, but failed to adjust the legend bar. The legend layout was across the map, which did not look well. Error in do.call(addMapLegend,

问题 I want to create multiple maps (similar to this example) using the apply family. Here a small sample of my code (~200 rows x 150 cols). (UN and ISO3 are codes for rworldmap): df <- structure(list(BLUE.fruits = c(12803543, 3745797, 19947613, 0, 130, 4), BLUE.nuts = c(21563867, 533665, 171984, 0, 0, 0), BLUE.veggies = c(92690, 188940, 34910, 0, 0, 577), GREEN.fruits = c(3389314, 15773576, 8942278, 0, 814, 87538 ), GREEN.nuts = c(6399474, 1640804, 464688, 0, 0, 0), GREEN.veggies = c(15508,

问题 I have a list of latitude and longitude coordinates, and wish to find out which country they all reside in. I modified an answer from this question about lat-long to US states, and have a working function, but I run into the problem that the worldHires map (from the mapdata package) is hideously out of date and contains a lot of obsolete countries such as Yugoslavia and the USSR. How would I modify this function to use a more modern package, such as rworldmap ? I have only managed to

问题 I have a reasonably high definition global map raster and want to plot to file, but cannot seem to maintain resolution. Plotting a restricted region works ok, but the whole world always ends up with reduced resolution, no matter what method I've used. Am I missing something here? I've often output high-res rasters before without this problem, but I'm unable to identify the cause in this case. To illustrate: require(raster) require(rworldmap) data(countriesCoarse); worldmap = countriesCoarse

问题 https://github.com/ramnathv/rMaps I tried reproducing this example and the map isn't showing: library(rMaps) crosslet( x = "country", y = c("web_index", "universal_access", "impact_empowerment", "freedom_openness"), data = web_index ) Do I not have a package that will allow this to happen. I have installed the following: rCharts rMaps jsonlite 来源： https://stackoverflow.com/questions/32830566/crosslet-package-not-working

问题 Good morning, I have spent a lot of time to figure out how can I add a country names directly on plot not like a part of legend, but like part of map. Im using package rworldmap, tried to use identifyCountries () - but it something for interaction (when a user clicks on the map), than I have found a such solution Administrative regions map of a country with ggmap and ggplot2 but it's for ggplot2, and too complicated. Im trying to do it with mapCountryData() . Hope for your help, thanks. data

问题 I want to plot multiple maps using rworldmap, where each column is a separate month and the rows are years. I know this can be done in ggmap using facet_grid. How can I do this using rworldmap? For example, the mydata file contains columns for the latitude , longitude , month and year of each point. My code so far: library(rworldmap) newmap <- getMap(resolution = "high") plot(newmap, xlim = c(110, 155), ylim = c(-35, -20), asp = 1) p1 <- read.csv("mydata.csv") points(p1$lon, p1$lat, col =
