使用as.data.frame绘制splom（）图形

Question

我需要使用带有splom()函数的lattice包构建as.data.frame图形，但它不起作用。

library(lattice)
data(Investment, package = "sandwich")
Investment <- as.data.frame(Investment, GNP)
splom(Investment|"Graphic", xlab = "Investment", ylab = "GNP")

Answer 1

你可以试试这个：

_drawRect = new Rectangle((int)_location.X - _halfDrawRectangleWidth, 
      (int)_location.Y - _halfDrawRectangleHeight, _spriteBall.Width, _spriteBall.Height);
