Heatmap fidelity
...ame the rows and then eliminate the 1st row
row.names(nba) <- nba$Name
nba <- nba[,2:20]
# nba2 <- nba[1:10,] ## use these if you only want to look @ 10 players
# Compute how "similar" players are by doing a correlation between their
statistical sets
psim = cor(t(nba))
# psim2 = cor(t(nba2))
# Note: everyone has a self-correlation of 1
diag(abs(psim))
# diag(abs(psim2))
# But the diagonal doesn't always look the same
heatmap(abs(psim))
# heatmap(abs(psim2))
