小编use*_*491的帖子

我刚刚在Mac OS X上安装了RStudio,版本10.7.3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"

任何想法,重启都没有用!!

干杯
