【R】直方图

hist(x, breaks = "Sturges",
     freq = NULL, probability = !freq,
     include.lowest = TRUE, right = TRUE,
     density = NULL, angle = 45, col = NULL, border = NULL,
     main = paste("Histogram of" , xname),
     xlim = range(breaks), ylim = NULL,
     xlab = xname, ylab,
     axes = TRUE, plot = TRUE, labels = FALSE,
     nclass = NULL, warn.unused = TRUE, ...)

 例如

>opar<-par(no.readonly=TRUE) 
>par(pin=c(2,2))
>par(mfrow=c(2,2))

>hist(文件名$列名,breaks=seq(100,450,13),col = "颜色",border = "颜色",lty = 数字，lwd = 数字，xlim=c(100,450),ylim=c(0,80),main="标题",xlab="横坐标",ylab="纵坐标",xaxt="n",yaxt="n")
    #xaxt=”n”为关闭x轴的坐标轴,yaxt=”n”为关闭y轴的坐标轴
    #lty，lwd线的类型与宽度
    #labels = TRUE，表示在每列头上标注数目,freq=FALSE 纵坐标可以显示概率，而不是数目

>axis= axis(1,at=seq(100,450,50),label=c(100,"" ,200,"" ,300,"" ,400, ""))
    #添加上坐标轴：1代表横坐标轴，2代表中纵坐标，3代表中上坐标，4代表中右坐标，100，450代表坐标起始和终止位点，50代表间隔
