bear =read.csv("densityexample.csv")

x = bear[,2]

y=density(x)

plot(y, main = "Distribution ofsample") #绘制常规坐标轴的密度曲线

par(mar=c(4, 2, 4, 6)+0.1) ##设置图形边距c(bottom,left, top, right)

plot(y,axes=F, main = "Distributionofsample",ylab = "")

#axes 设置不显示坐标轴

axis(side=4, col.axis="black")

#side 设置新坐标轴的方向

mtext(4,text="Density",line=3)
