Hello,


The function La.eigen, called by cmdscale in the package mva behaves an
unexplicable way (for me).

The following lines show what happened.
I tried the very same on linux, and it worked fine.




>a <- matrix(c(1,2,3,2),3,3)
>a
     [,1] [,2] [,3]
[1,]    1    2    3
[2,]    2    1    2
[3,]    3    2    1
>library(mva)
>cmdscale(a)
Error in La.eigen(Tmat, symmetric = TRUE) : 
	On entry to DSYEV  parameter number 8 had an illegal value



Regards,



Laurent



PS: I had trouble during the 'make check' installation step. I was pointed out
it was a known problem with modreg on SGIs. I think both things are
independant,
but, well, one never knows...
