Usage: bp = grboxmedian (x {, col})
Input:
x n x 1 vector
col color
Output:
bp composed graphical object

Example:

library ("graphic")

t  = (normal(25)-8)|(normal(25)+8)|normal(100)|(normal(10)+25)

bp = grboxmedian (t)

d  = createdisplay (1,1)

show (d, 1, 1, bp)

Result:

shows a "robust" boxplot
