我正在嘗試創建一張地圖，在其中使用散點圖顯示每個歐洲國家的出口數量和類別。這是我試圖代表的資料：

使用以下代碼：
library(giscoR)
borders <- gisco_get_countries(
epsg = "3035",
year = "2020",
resolution = "3",
country = idf$Country
)
merged <- merge(borders,
idf,
by.x = "CNTR_ID",
by.y = "Country",
all.x = TRUE
)
library(tidyverse)
symbol_pos <- st_centroid(merged, of_largest_polygon = TRUE)
separate_coords = symbol_pos %>% mutate(lat = unlist(map(symbol_pos$geometry, 1)), long = unlist(map(symbol_pos$geometry, 2)))
sympos = data.frame(Country = separate_coords$CNTR_ID, lat = separate_coords$lat, long = separate_coords$long)
merged <- merge(merged,
sympos,
by.x = "CNTR_ID",
by.y = "Country",
all.x = TRUE
)
ggplot()
geom_sf(data = merged, size = 0.1)
geom_scatterpie(data = merged, aes(x = long, y = lat, r = Total), cols = LETTERS[1:7])
coord_sf(xlim = c(2377294, 6500000), ylim = c(1413597, 5228510))
它給了我這個錯誤：
Error in rowSums(data[, cols]) : 'x' must be numeric
我正在嘗試創建與此類似的地圖：
如果有人能提供一些關于如何修復錯誤的提示，我將不勝感激。謝謝。

uj5u.com熱心網友回復：
請在下面找到滿足您要求的一種可能的解決方案。主要問題是geom_scatterpie()需要一個資料框而不是一個sf物件。所以你需要使用as.data.frame()inside geom_scatterpie()。我還借此機會簡化了您的代碼。
