Hie all.
I am working on scaling my data into a fited range of -60 0 and 60,
with increases of 20.
when i use heatmap,2 the error messgae i get is as follows
heatmap.2(m, margins= c(9,9), col = bluered(64), trace=c("none"),
breaks=c(seq(-60,0,60/20)), symkey=TRUE, density.info="histogram",
cexRow=1,)
Error in image.default(1:nc, 1:nr, x, xlim = 0.5 + c(0, nc), ylim = 0.5 + :
must have one more break than colour
Can any one help on how i can get around this problem.
Your help is most appreciated.
