To avoid overlapping (as in the scatterplot beside), it divides the plot area in a multitude of small fragment and represents the number of points in this fragment. There are several types of 2d density plots. Each has its properggplot2function. This post describes all of them. histogram)....

与plot相似,qplot()的基本参数是x、y,分别代表所要绘制图像的x轴与y轴,并且为了和数据框高度契合(我也十分鼓励将变量都放进数据框中规整起来),qplot还提供了参数data,控制传入的数据框名称,这样在qplot()中涉及数据框中变量的参数就可以直呼其名而不用加$; ...
