如何使用R基本地块在grid.newpage？(How to use R base plots in

是否有可能“迫使”在R基本绘图grid包的grid.newpage ？ 例如，这工作得很好：

library(grid)
grid.newpage()
vp1 <- viewport(x=0,y=0.5,width=0.5, height=0.5, just = c("left", "bottom"))
vp2 <- viewport(x=0.5,y=0,width=0.5, height=0.5, just = c("left", "bottom"))
pushViewport(vp1)
grid.rect()
grid.text("vp1", 0.5, 0.5)
upViewport()
pushViewport(vp2)
grid.rect()
grid.text("vp2", 0.5, 0.5)

。

但是，如果我尝试这样：

grid.newpage()
vp1 <- viewport(x=0,y=0.5,width=0.5, height=0.5, just = c("left", "bottom"))
vp2 <- viewport(x=0.5,y=0,width=0.5, height=0.5, just = c("left", "bottom"))
pushViewport(vp1)
grid.rect()
print(plot(1,2))
grid.text("vp1", 0.5, 0.5)
upViewport()
pushViewport(vp2)
grid.rect()
print(plot(1,2))

R基本情节刚过，乘坐grid.newpage 。 采用par(new=T)也没有帮助。

Answer 1:

因为没有人回答这个问题，我会做我自己。 作为Andrie表示，这个问题的答案是在这里 。 你需要gridFIG()函数从gridBase包绘制在R基本情节plot.new()代替grid.newpage()

library(grid)
library(gridBase)
plot.new()
vp1 <- viewport(x=0,y=0.5,width=0.5, height=0.5, just = c("left", "bottom"))
vp2 <- viewport(x=0.5,y=0,width=0.5, height=0.5, just = c("left", "bottom"))
pushViewport(vp1)
grid.rect()
grid.text("vp1", 0.5, 0.5)
par(new=TRUE, fig=gridFIG())
plot(1,2)
upViewport()
pushViewport(vp2)
grid.rect()
grid.text("vp2", 0.5, 0.5)
par(new=TRUE, fig=gridFIG())
plot(1,2)
