Help on R performance using aov function
Hi,
I?m trying to replace some SAS statistical functions by R (batch calling).
But I?ve seen that calling R in a batch mode (under Unix) takes about 2or 3
times more than SAS software. So it?s a great problem of performance for me.
Here is an extract of the calculation:
stoutput<-file("res_oneWayAnova.dat","w");

p<-list_param[[i]]
aov_<-aov(A[,p]~ A[,"wafer"],data=A);
anova_<-summary(aov_);
if (!is.na(anova_[[1]][1,5]) & anova_[[1]][1,5]<=0.00...
