我必须在我的情节中绘制网格。我找到了一个用于此目的的解决方案
barplot(1:50)
grid()
box()
par(new = TRUE)
barplot(1:50)
以下是情节 我很好。但为什么我应该两次打电话给barplot。是否有一些简单的方法将网格移动到背景?
我面临以下问题是我的情节(boxplot)
png("test2.png")
bm = boxplot(exuper, fuper, super, tuper, dat$uper, outline = F, names=names, panel.first = grid())
box()
dev.off()
和错误是
Error in int_abline(a = a, b = b, h = h, v = v, untf = untf, ...) :
plot.new has not been called yet
> box()
Error in box() : plot.new has not been called yet
