Re: [R] Output formatting in PDF

Hi There is also the basic option of using the grid package and viewports. You can then place the plots where you want and annotate them pdf(file= paste0("01", ".pdf"), height = 3.5, width = 7, paper = "special", onefile = TRUE, family = "Helv

Re: [R] Hclust

Not for hclust() since it provides results for all clusters from 1 to n (the number of observations). Adding a point can change the definition of the clusters. You could use cutree() to assign the observations to clusters for a particular number of clusters, but then you must decide what rule to

Dear Georg, My 2 eurocents. - I'd place the Roxygen header just above the function instead of instead the function. That makes your function more readable. - Use only tags that Roxygen knows about. - Use version controle instead of the version, created and updated tags. - You can specify the auth
