您可以使用melt()函数,然后使用geom_BoxPlot()。
首先复制数据(感谢Excel):
vec <- c(c(27, 32, 31, 28, 20, 28, 10, 29, 15, 29),
+ c(31, 33, 20, 28, 21, Â 9, 14, 21, 34, 33),
+ c(27, 33, 28, 23, 26, 33, 19, 11, 26, 30),
+ c(33, 17, 10, 31, 10, 32, 10, 29, 31, 28),
+ c(25, 10, 29, 34, 32, 33, 28, 32, 32, 32),
+ c(32, 19, 13, 32, 26, 20, Â 9, 26, 32, 33),
+ c(33, 32, 18, 26, 27, 28, 29, 32, 24, 25),
+ c(33, 34, 32, 30, 27, 31, 22, 32, 33, 30),
+ c(32, 34, 31, 22, 17, 31, 11, 27, 18, 23),
+ c(26, 10, 30, 30, 27, Â 4, Â 4, Â 4, Â 4, 4))
myMatrix <- matrix(data=vec, ncol=10, byrow=TRUE)
然后熔化并绘图:
library(reshape)
library(ggplot2)
ggplot(data=melt(as.data.frame(myMatrix)), aes(variable, value)) + geom_boxplot()
此外,正如哈德利(很久以前)在评论中建议的那样,不需要将矩阵转换为数据帧:
ggplot(data=melt(myMatrix), aes(as.factor(X2), value)) + geom_boxplot()
