Удалить цветную рамку вокруг ggplot - PullRequest

Я добавляю ggplots к viewportsggplot, и viewport имеют одинаковый фон цвет.Моя проблема в том, что мой ggplots окружен белым прямоугольником, и мне кажется, что я не могу найти возможность удалить его, используя theme.Есть идеи?

enter image description here

library(grid)
library(ggplot2)

Pie_chart <- ggplot(df , aes(x = "", y = prop_1, fill = rank) ) +
  geom_bar(stat="identity", width=2) +
  coord_polar("y", start = 0) + 
  labs(x = NULL, y = NULL, fill = NULL, title = "") + 
  theme(axis.line = element_blank(), 
        axis.text = element_blank(), 
        axis.ticks = element_blank(), 
        legend.position="none")+
  theme(plot.margin = unit(c(0.0, 0.0, 0.0, 0.0), "cm"),
        plot.background = element_rect(fill = "blue"),
        panel.background = element_rect(fill = "blue"))

lower_section_viewport <- viewport(
  layout = grid.layout(nrow = 1, ncol = 2, 
                       widths = unit(c(2, 1), c("null", "null"))), 
  name = "lower_section")

grid.newpage()
pushViewport(lower_section_viewport)
grid.rect(gp = gpar(fill = "blue", col = "blue" ))

pushViewport(viewport(layout.pos.row = 1, layout.pos.col = 2))
print(Pie_chart, vp = current.viewport())
upViewport()

    -11L))

Это аргумент colour = NA в theme(plot.backround = ... ), который вы ищете.

Pie_chart <- ggplot(df , aes(x = "", y = prop_1, fill = rank) ) +
  geom_bar(stat="identity", width=2) +
  coord_polar("y", start = 0) + 
  labs(x = NULL, y = NULL, fill = NULL, title = "") + 
  theme(axis.line = element_blank(), axis.text = element_blank(), axis.ticks = element_blank(), legend.position="none")+
  theme(plot.margin = unit(c(0.0, 0.0, 0.0, 0.0), "cm"),
        plot.background = element_rect(fill = "blue", 
                                       colour = NA), # here it is
        panel.background = element_rect(fill = "blue"))
