我刚刚在 Mac OS X 版本 10.7.3 上安装了 RStudio。执行以下命令后
library(ggplot2)
qplot(mpg, wt, data=mtcars)
我收到以下错误:
Error in grid.Call(L_textBounds, as.graphicsAnnot(x$label), x$x, x$y, :
Polygon edge not found
In addition: Warning messages:
1: In grid.Call(L_textBounds, as.graphicsAnnot(x$label), x$x, x$y, :
no font could be found for family "Arial"
2: In grid.Call(L_textBounds, as.graphicsAnnot(x$label), x$x, x$y, :
no font could be found for family "Arial"
我该如何解决?
