R language Histogram

hist (x, breaks = "Sturges",     freq = NULL, probability =!freq,     include.lowest = true, right = true,     density = N ULL, angle = $, col = null, border = NULL,     main = paste ("Histogram of", XName),     Xlim = range (breaks), Ylim = NUL L,     Xlab = XName, Ylab,     axes = true, Plot = true, labels = FALSE,     nclass = NULL, warn.unused = True, ...)

For example:

> hist (filename column name, Breaks=20,col = "color", border = "Color", lty = number, LWD = number, xlim=c (100,450), main= "title", xlab= "horizontal axis", ylab= "ordinate", xaxt= "n")    #xaxt = "n" is the axis #lty off the x-axis    , the type and width of the LWD line
    #labels = TRUE, indicating the number of labels on each column header, the Freq=false ordinate can show the probability, not the number

>axis= Axis (1,at=seq (100,450,50))    #添加上坐标轴: 1 for the horizontal axis, 2 for the middle ordinate, 100,450 for the start and end of coordinates, and 50 for the interval
