rdataset is a collection of 597 datasets that were originally distributed alongside the statistical software environment "R" and some of its add-on packages.
Datasets which are available in R can be used in Scilab with rdataset. The toolbox needs around 50 MByte.
> library(MASS) >print(mean(survey$Wr.Hnd,na.rm=TRUE),digits=17)  18.669067796610168
The same can be done in Scilab
[data,desc] = rdataset_read("MASS","survey"); mean_hand=mean(thrownan(data.Wr_Hnd)) mean_hand = 18.669068 disp(18.669067796610168-mean_hand) - 1.066D-14
