Hello Jim, I have a several matrices stored in allGrid <- list()
I am using: color2D.matplot(grid, extremes = c("green", "red"), vcol = "black", nslices = 60, show.legend=TRUE,axes=FALSE,show.values=TRUE, xlab="Columns",ylab="Rows") for each of "grid" in "allGrid". Each "grid" is a matrix with element range from 0 to max number of allGrid, say 40. I want to plot many "grid" with color represents the number (density). But I cannot fix the color scale and anchor the maximum value to a fixed number. I have tried many things but nothing works. Just the extra is: I cannot make the color from green (small number) -> yellow (middle number) -> red (big number). Sometimes, the plot turns black and white. Please help me.
