• data viz I couldn't do in Excel

• A few lines of code = new data viz!

nba_heatmap <- heatmap(nba_matrix, 
                       Rowv=NA, Colv=NA, 
                       col = cm.colors(256), scale="column")

My first cluster dendrogram

# make the cluster dendrogram object using the hclust() and dist() functions
hc <- hclust(dist(rbind(P1, P2, P3, P4, P5, P6, P7, P8, P9, P10, P11, P12)))  

# plot the cluster dendrogram 
plot(hc, xlab = ("Patient Samples"))
