I have a data set which is comprised of counts, that is, the number of times a
mass spectrometer measured a particular mass at a particular time (the rows and
columns of the table). Is there a way to make a plot so that it draws a square
at the mass/time spot on the graphic if there is a count and leave it empty if
it's empty?
Hi pofigster,
You can do this with color2D.matplot in the latest version of plotrix
(2.4-8) that has just been uploaded (may take a day or two to appear):
color2D.matplot(mydata,1,0,1)
will produce a plot with purple rectangles at each number and white
(default, you can change it) rectangles where there are NAs.
