All,
I frequently make spreadsheets in Excel in which I rank values in columns
by stop-light colors (red is bad, yellow is OK, green is good).
Image and heatmap expect a matrix in which all the data are in the same
scale, but I frequently have different scales in different columns. ie.
Column one runs from 1-10 while column 2 runs from 1-100. I thus need to
define a separate color ramp for each column. In addition, sometimes the
smaller numbers are colored green, while sometimes the larger numbers are
preferred and colored green. I also want to print in each cell the numeric
value, and I need to show row names. A crude example without the color:
RowNames Col1 Col2
----------------------------------------------
Row1 1 1
Row2 5 50
Row3 7.5 80
Row4 10 99
......
Is there any R package that can do something similar? Can I create a plot
that is a matrix of rectangles and get color and text that way?
Any help is greatly appreciated.
Thanks,
John
