我做了以下rworldplot
:
library(rworldmap)
#> Loading required package: sp
#> ### Welcome to rworldmap ###
#> For a short introduction type : vignette('rworldmap')
library(RColorBrewer)
test.data <- data.frame(
country = c('USA','Denmark','Australia','Germany'),
value = c(4000,1000,2300,100)
)
sPDF <- joinCountryData2Map(test.data,joinCode = "NAME",nameJoinColumn = "country")
#> 4 codes from your data successfully matched countries in the map
#> 0 codes from your data failed to match with a country code in the map
#> 239 codes from the map weren't represented in your data
colourPalette <- brewer.pal(4,'Reds')
mapParams <- mapCountryData(sPDF, nameColumnToPlot="value", colourPalette=colourPalette, catMethod=c(0,500,1000,2300,5000), addLegend=FALSE, mapTitle = 'TEST')
do.call( addMapLegend, c( mapParams
, legendLabels="all"
, legendWidth=0.5 ))
为了清楚起见,我还想添加一个条形图:
library(ggplot2)
barplot <- ggplot(test.data, aes(x=reorder(country,-value), y = value)) +
geom_bar(stat='identity', fill = 'darkred') +
theme_classic()
barplot
理想情况下,我想使用例如将 rworldmap 图和 ggplot 组合在一个图中。 grid.arrange
或cowplot
包裹。我知道这对于不同的人来说很容易ggplot
然而反对do.call
直接绘制 rworldmap,因此我不知道如何将其变为 grid.arrange(<rworlddmapplot>, barplot)
这样的字。
最佳答案
cowplot 中的 plot_grid()
函数可以采用函数参数来绘制您想要显示的图。
library(rworldmap)
#> Loading required package: sp
#> ### Welcome to rworldmap ###
#> For a short introduction type : vignette('rworldmap')
library(RColorBrewer)
test.data <- data.frame(
country = c('USA','Denmark','Australia','Germany'),
value = c(4000,1000,2300,100)
)
draw_map <- function(test.data) {
function() {
sPDF <- joinCountryData2Map(test.data,joinCode = "NAME",nameJoinColumn = "country")
colourPalette <- brewer.pal(4,'Reds')
mapParams <- mapCountryData(sPDF, nameColumnToPlot="value", colourPalette=colourPalette, catMethod=c(0,500,1000,2300,5000), addLegend=FALSE, mapTitle = 'TEST')
do.call( addMapLegend, c( mapParams
, legendLabels="all"
, legendWidth=0.5 ))
}
}
library(ggplot2)
barplot <- ggplot(test.data, aes(x=reorder(country,-value), y = value)) +
geom_bar(stat='identity', fill = 'darkred') +
theme_classic()
library(cowplot)

plot_grid(barplot, draw_map(test.data))
