I'm having a problem when using heatmap. Even though the diagonal of my matrix is all the same value, the diagonal of my heatmap is not all the same color. Any suggestions?
Here is some reproducible code: ######################################### # Get data nba <- read.csv("http://datasets.flowingdata.com/ppg2008.csv", sep=",") # Reorder nba <- nba[order(nba$PTS),] # Name the rows and then eliminate the 1st row row.names(nba) <- nba$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)) ##################################### Thanks! -Steven Wolf Lyman Briggs College Department of Physics and Astronomy Michigan State University [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
