ggplot绘制散点图的函数是()
A: point
B: line
C: geom_point
D: geom_line
A: point
B: line
C: geom_point
D: geom_line
C
举一反三
- ggplot包中用于图层控制的函数是? A: position() B: mapping() C: stat() D: geom()
- 下面哪条表达式可以创建一条从点(2,3)到(4,5)的线段? A: Line(2,4,3,5) B: Line(2,3,4,5) C: Line((2,3),(4,5)) D: Line(Point(2,3),Point(4,5))
- 使用ggplot做柱状图,应该使用哪个命令? A: geom_bar B: geom_histogram C: geom_line D: geom_point
- 在ggplot绘图系统中,几何映射geom与统计变换stat是成对出现
- 下面代码中,没有定义内部类或者错误定义了内部类的是()。 A: public Class Line { int length; Class Point {//内部类代码}} B: public Class Line { public Point getPoint() { return new Point(){//内部类代码}; }} C: public Class Line { //外部类代码} Class Point {//内部类代码} D: public Class Line { public int calcLength() { Class Point {//内部类代码} }}
