Dear R users,
Please consider the following example:
tmp <- matrix(rnorm(100),10,10)
tmp[upper.tri(tmp, diag = TRUE)] <- NA
heatmap(tmp, col = heat.colors(200), Rowv=NA, Colv=NA)
I have three questions:
(1) How would I change the axis labels from 1:10 to c("apples",
"pears",
"bananas", "kiwis", "watermelons",
"grapefruits", "strawberries", "blueberries",
"cherries", "grapes")?
(2) How would I put the axis labels to the top and right, rather than on the
bottom and left?
(3) How would I add a key (with the appropriate color ramp) to the bottom right
corner of the graph? (I recognize that this can be done with the "Key =
TRUE"
option of the heatmap.2 function in the gplots package, but I want to use that.
I want to make the key myself so that I can fully customize it.)
Thank you all very much in advance.
