ggplot(mpg, aes(x = displ, y = hwy, shape = cty)) + geom_point(size = 3) + scale_shape_binned() (3)scale_shape_ordinal() 这个函数也是有点鸡肋啊,说明文档呢? # 有序变量示例 mpg$ordered_class <- factor(mpg$class, levels = c("2seater", "compact", "midsize", "minivan", "...

#最后scale_size诸多设置也可以用scale_size_area()进行设置。 1 #接下来,了解下scale_alpha()相关设置,基本上和scale_size()类似p+geom_point()+scale_alpha("花瓣宽度",breaks=c(0.2,0.4,0.6,0.8))#强行对透明度设置自定义分组 1 2 p+geom_point()+scale_alpha("花瓣宽度",breaks=c(0.2,0.4,0.6,0.8...

ggplot(mtcars, aes(x = wt, y = mpg)) + geom_point(aes(shape = cyl, color = cyl))也可以用以下函数调节分组的形状，颜色，大小 • scale_shape_manual() : to change point shapes• scale_color_manual() : to change point colors• scale_size_manual() : to change the size of ...
#可以通过scale_colour_brewer()或scale_colour_manual()函数自定义点的颜色;通过scale_shape_manual()函数实现自定义点的形状。为了说明问题,这里将分组变量同时赋值给颜色属性和形状属性。 ggplot(data = df, mapping = aes(x = x, y = y, colour = z, shape = z)) + geom_point(size = 3) + scal...
scale_shape_manual()函数来修改点形。在R中,不同数字表示的点形如下: 对于点形1-20,颜色都可由colour参数来绘制,21-25边框线和实心区域的颜色分别由colour和fill参数来控制。 ggplot(heightweight,aes(x=ageYear,y=heightIn,shape=sex))+ geom_point(size=3)+scale_shape_manual(values = c(1,4)) ...
