Я пытаюсь составить тепловую карту над картой США. Код создает карту США, но не отображает на ней никаких данных. Ни это не дает никакой ошибки! Я новичок в R, поэтому любая подсказка / идея была бы отличной.

Я пытаюсь получить что-то вроде следующего изображения (без текста на карте) для X, Y and Z
отдельно для каждого type (say, DE, TS, etc.)
. Код, который я пробовал, выглядит следующим образом: -
library(ggplot2)
library(maps)
ggplot() +
geom_polygon(data=states, aes(x=long, y=lat, group=group), color="blue", fill="white")+
geom_tile(data=df, aes(x=long, y=lat, fill = Y), alpha=0.3)+
scale_fill_gradient(low = "blue", high = "red")
