运行示例时，Rayshader plot_gg崩溃 [英] Rayshader plot_gg crashes while running example

问题描述

我已尝试从 https://www.rayhader示例中重现.tylermw.com/3d-ggplots-with-rayshader/:

library(rayshader)
library(ggplot2)
library(tidyverse)
library(sf)
library(viridis)

nc = st_read(system.file("shape/nc.shp", package="sf"), quiet = TRUE)
gg_nc = ggplot(nc) +
  geom_sf(aes(fill = AREA)) +
  scale_fill_viridis("Area") +
  ggtitle("Area of counties in North Carolina") +
  theme_classic()

plot_gg(gg_nc, multicore = TRUE, width = 6 ,height=2.7, fov = 70)

但是运行plot_gg行时，出现以下错误消息:

but running the plot_gg line i get following error message:

if(哪一类％in％c("text"，"line")){错误:参数长度为零

关于那里发生的事情有什么想法吗?

Any idea on what's going on there?

推荐答案

将代码修改为:

theme_set(theme_classic())

gg_nc = ggplot(nc) +
  geom_sf(aes(fill = AREA)) +
  scale_fill_viridis("Area") +
  ggtitle("Area of counties in North Carolina")

plot_gg(gg_nc, multicore = TRUE, width = 6 ,height=2.7, fov = 70)
