- Produces a symmetry plot of a numerical vector.
- REQUIRED ARGUMENTS
- x - a numeric vector
- The distance from each point above the median to the
median is plotted against the distance to the
corresponding point below the median. A straight line
corresponds to a perfectly symmetric sample.
- x <- rnorm(20)
sym.plot(x) # points should lie reasonably close the line
