bplot.xy | R Documentation |
Draws boxplots for y by binning on x. This gives a coarse, but quick, representation of the conditional distrubtion of [Y|X] in terms of boxplots.
bplot.xy(x, y, N = 10, breaks = pretty(x, N, eps.correct = 1), style = "tukey", outlier = TRUE, plot = TRUE, xaxt = "s", ...)
x |
Vector to use for bin membership |
y |
Vector to use for constructing boxplot statistics. |
N |
Number of bins on x. Default is 10. |
breaks |
Break points defining bin boundaries. These can be unequally spaced. |
style |
Type of boxplot default is "tukey". The other choice is "quantile" where the whiskers are drawn to the 5 and 95 percentiles instead being based on the inner fences. |
xaxt |
Plotting parameter for x-axis generation. Default is to produce an x-axis. |
outlier |
If true outliers (points beyond outer fences) will be added to the plots. |
plot |
If false just returns a list with the statistics used for plotting the box plots. |
... |
Any other optional arguments passed to the bplot.obj function see the help file for bplot for details. |
