Hi, I get this error when I try to run a fitmaanova on my data. anova.fix<-fitmaanova(mydata_norm, formula= ~Array+Dye+Treatment) Error in ma.svd(X, 0, 0) : BLAS/LAPACK routine 'DORGLQ' gave error code -5 In addition: Warning message: In any(parsed.formula$random) : coercing argument of type 'double' to logical I'm a newbie in R. I'm working on arch linux and I tried with lapack and blas packages, I also try it with the complete atlas-lapack package but the same error came with bot try. Does anyone have any ideas what could causing this and how to resolve it.
