Dear all,

I'm trying to do some clustering analysis in a microarray expression data
set, for that I was trying to implement the adSplit package. Even when
running the example in the vignette, when trying to use the diana2means( )
function I get an error:

> library(golubEsets)
> data(Golub_Merge)
> e <- exprs(Golub_Merge)
> vars <- apply(e, 1, var)
> e <- e[vars > quantile(vars,0.9),]
>
> diana2means(e)
Error in .C(twins, n, jp, as.double(x2), dv, dis = double(if (C.keep.diss)
length(dv) else 1),  :
  'name' must be a string (of length 1) or native symbol reference

Could anyone point me to the right direction on to how to fix this?
