##### Plot Histograms

These are methods for objects of class "histogram", typically produced by hist.

Keywords
hplot, iplot
"plot"(x, freq = equidist, density = NULL, angle = 45, col = NULL, border = par("fg"), lty = NULL, main = paste("Histogram of", paste(x$xname, collapse = "\n")), sub = NULL, xlab = x$xname, ylab, xlim = range(x$breaks), ylim = NULL, axes = TRUE, labels = FALSE, add = FALSE, ann = TRUE, ...) "lines"(x, ...) ##### Arguments x a histogram object, or a list with components density, mid, etc, see hist for information about the components of x. freq logical; if TRUE, the histogram graphic is to present a representation of frequencies, i.e, x$counts; if FALSE, relative frequencies (probabilities), i.e., x$density, are plotted. The default is true for equidistant breaks and false otherwise. col a colour to be used to fill the bars. The default of NULL yields unfilled bars. border the color of the border around the bars. angle, density select shading of bars by lines: see rect. lty the line type used for the bars, see also lines. main, sub, xlab, ylab these arguments to title have useful defaults here. xlim, ylim the range of x and y values with sensible defaults. axes logical, indicating if axes should be drawn. labels logical or character. Additionally draw labels on top of bars, if not FALSE; if TRUE, draw the counts or rounded densities; if labels is a character, draw itself. add logical. If TRUE, only the bars are added to the current plot. This is what lines.histogram(*) does. ann logical. Should annotations (titles and axis titles) be plotted? ... further graphical parameters to title and axis. ##### Details lines.histogram(*) is the same as plot.histogram(*, add = TRUE). ##### See Also hist, stem, density. ##### Aliases • plot.histogram • lines.histogram ##### Examples library(graphics) (wwt <- hist(women$weight, nclass = 7, plot = FALSE)) plot(wwt, labels = TRUE) # default main & xlab using wwt$xname plot(wwt, border = "dark blue", col = "light blue", main = "Histogram of 15 women's weights", xlab = "weight [pounds]") ## Fake "lines" example, using non-default labels: w2 <- wwt; w2$counts <- w2$counts - 1 lines(w2, col = "Midnight Blue", labels = ifelse(w2$counts, "> 1", "1"))
