I am using color2D.matplot to plot a matrix about 400 by 200.
The values in the matrix are 0:5 and NA. The resulting plot is not color, but
shaded b/w. I tried to figure out how to add colors, I would like something
like c(blue, green, red, cyan, green)
#example
motifx <- matrix(NA, nrow=100,ncol=20)
motifx[,1:5] <- 1
motifx[,6:10] <- 2
motifx[,11:15] <- 3
motifx[,15:19] <- 4
motifx
color2D.matplot(motifx, na.color="white",show.legend=TRUE)
or is there a better function to use than color2D.matplot?
