sampcdf(x [,quiet:T, keep:T, draw:T] [,graphics keywords]), x REAL vector with no MISSING elements |

sampcdf(x [,graphics keywords]), where x is a REAL vector, draws the sample cumulative distribution function (CDF) of x. The graphics keywords may include 'xlab', 'ylab', 'title', 'linetype', 'show' and 'keep'. See topic 'graph_keys'. Any MISSING elements are removed sampcdf(x, quiet:T [,graphics keywords]) does the same except any warning messages are suppressed. sampcdf(x, save:T [,graphics keywords]) doesn't draw the CDF. Instead it returns as value structure(x:xvals,y:yvals [,graphics keywords],lines:T), where xvals and yvals are REAL vectors defining the lines making up the CDF. Note that any graphics keyword phrases that are arguments are components of the structure. sampcdf(x, save:T, draw:T [,graphics keywords]) both draws the CDF and returns a structure. Example: Both Cmd> sampcdf(x, xlab:"Bunny weight",\ title:"Sample CDF of Bunny Weights", wind:1) and Cmd> GRAPHWINDOWS[1] <- sampcdf(x, save:T, xlab:"Bunny weight",\ title:"Sample CDF of Bunny Weights") will draw a sample CDF in graphics window 1.
