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?
