I've got the graphic with this: a=c(120,40,75,85,55,75,55,90,90,55,155) plot(ecdf(a)) How can I draw lines to show the lower quatile and upper quartil? I only know there is the argument lines(), but I don't know how to use it -- View this message in context: http://r.789695.n4.nabble.com/How-can-I-draw-a-line-in-empirical-distribution-function-tp3090675p3090675.html Sent from the R

...ymmetrical window. The second question is more important and more complicated,if possibal,plese give me a detailed description.In useing speex,I've found that although the coding quality is great,the speed is a bittle low, so i want to use SSE instructions to improve it,but when using vector quatilization,speex use sub_vectors,and many of the sub_vectors sizes are like 5,10,but not the times of 4,so SSE instructions can not improve so much.So I want to know,how do you train and get the fixed codevect,and using your method,can I train and get the codevect,and the subvect size is 4,8,12,16,20,and cod...

I am calling quantiles as follows. I don't understand why sometimes the columns (data values) above 95% are returned as "NULL"!! When I drop the percentile down to 92%, I see colums appearing. Why would any quantile be empty? I see sometimes that 95% percentile is being chosen as "1" for my data between 0 and 1, where obviously there's no column value equal to 1. But
