boxplot_h: Makes horizontal boxplots

In PrincetonUniversity/lmisc: Miscellaneous functions for plotting and performing various small tasks

Description

Makes horizontal boxplots

Usage

boxplot_h(x, ycoord, n, inhgt = 20, whiskhgt = 5, bcol = "black",
  bfill = "grey", pcex = 1, lwd = 1, pch = 20)

Arguments

x	Vector of the 6 boxplot statistics (e.g. 5, 25, 50, 75, 95th percentile and mean)
ycoord	Y coordinate for plotting boxplot
n	Number of boxplots to be placed on plot
inhgt	Height of the interquartile box, scaled to size of device and number of boxes to be plotted
whiskhgt	Height of the 95th percentile whiskers, scaled in the same way as inhgt
bcol	A 1 or 4 element vector of colors for whiskers, interquartile box, median line, and mean point
bfill	Fill color for interquartile box
pcex	Size of point indicating the mean
lwd	A 1 or 3 element vector of widths for whiskers, interquartile box, and median line

Details

To be used with dummy call to plot(). Specify the number of boxes to be placed on the Y axis. The parameters for bcol and lwd will recycle the first element if the vector length is less than 4, and will only use the first 4 elements if it is longer.

Value

Boxplot

Examples

x <- lapply(1:4, function(x) box_stats(sample(1:100, 10)))
plot(c(1, 100), c(0, 5), pch = "", xlab = "value", ylab = "", yaxt = "n")  
#for(i in 1:length(x)) boxplot_h(x[[i]], ycoord = i, n = 4)
#for(i in 1:length(x)) boxplot_h(x[[i]], ycoord = i, n = 4, pch = 5, pcex = 2)
#for(i in 1:length(x)) boxplot_h(x[[i]], ycoord = i, n = 4, bcol = "red", bfill = "grey", whiskcol = "grey")
for(i in 1:length(x)) {
  boxplot_h(x[[i]], ycoord = i, n = 4, bcol = c("black", "grey40", "red", "blue"), bfill = "grey80", 
            lwd = c(2, 1, 7), whiskcol = "grey")
}
