Re: [R] how to change the "quantile" method in bwplot

2009-07-22 Thread Jun Shen
Thanks to Deepayan's suggestion, I was able to use boxplot.stats to specify type=6 to calculate quantiles by creating my own stats function as follows, my.boxplot.stats<-function(y,subscripts,...)boxplot.stats(quantile(y,type=6),...) And then call bwplot(Result~Group,data=d2,stats=my.boxplot.sta

for teaching purposes I wrote a corresponding function; cf. qbxp.stats (as well as qboxplot ...) in package MKmisc. hth, Matthias Deepayan Sarkar schrieb: On Tue, Jul 21, 2009 at 7:47 AM, Jun Shen wrote: Uwe, Thank you for your reply. I am still not very clear about the meanings of the ar

Uwe, Thank you for your reply. I am still not very clear about the meanings of the arguments in the stats function. To make it clearer, quantile() uses type=7 as default method. I believe this is the method bwplot() uses to calculate the quantiles. I want to use type=6 method for bwplot(). How
