我想将 x 轴值作为 2002 到 2011 年到相应的箱线图,每个分别显示从 2002 年到 2011 年的数据。一定有什么诀窍!
代码:
d = read.table("C:/sample.txt", sep="\t", header=TRUE)
attach(d)
summary(d)
boxplot(2002, 2003,2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011,
data=d, boxcol="blue", medcol="red", whiskcol="blue",
staplecol="blue", ylim = c(0, 1), lty=1, las=1, ylab = "NDVI",
outline = FALSE, boxfill = FALSE)
