I have done a cluster analysis doing:

1-clusNorth <-hclust(dist(Artorious)^2, method="ward") 2-clusNorth$labels <-Artorious$Name ## to show the case names and not numbers
3-dend1 <- as.dendrogram(clusNorth)
4-plot(dend1)

My Dendrogram is now showing the names of my cases in the dataframe on the x axis

1                    OMNICELL INC COM  
2                GETTY IMAGES INC COM 
3     INTERCONTINENTALEXCHANGE IN COM
4         OPTIONSXPRESS HLDGS INC COM  
5          SUPERIOR WELL SVCS INC COM 
6                         HCP INC COM  
7      SENIOR HSG PPTYS TR SH BEN INT  
8     NATIONWIDE HEALTH PPTYS INC COM  
9            DUKE REALTY CORP COM NEW

12           FLEXTRONICS INTL LTD ORD  
13                     VENTAS INC COM


However with 60 cases the names above are not fitting neatly into plot. Can someone advice on plot
Parameters to fix the size of dendrogram and see the full names on X axis?

Thanks.

Neil
