Another interesting tutorial to show how to drive R scripts from Excel. http://shashiasrblog.blogspot.com/2013/10/vba-front-end-for-r.html
The quickest setup for R available in Excel (UDF's) functions working on Excel ranges, and the easiest one: http://bert-toolkit.com/
eg. I wrote these in BERT config file (a file in R format) to get clustering functionality
KMEANS_CLUST <- function( mat, ncenters ){ kmeans(mat,centers = ncenters) }
HTREE_CLUST<- function ( mat, cutheight ) {
myclust<-hclust(dist(mat));
myclust<-cutree(myclust,h=cutheight);
return(myclust)
}
