I am now somewhat familiar with cummeRbund and have all my plots already except for one: a dispersion plot. I know dispersionPlot only runs on a cuffData object, however I don;t know how to create a cuffData object. Ive looked at the cuffData help file but the usage is not clear to me.
cuff <- readCufflinks(genome = 'rn6', gtfFile = "genes.gtf",rebuild = TRUE)
So the code is successful (creates a "disp" value in the environment window)
however when i try to veiw it I get the following error:
*tmp*, "SCALE_X", value = 1L) : replacement has 1 row, data has 0 In addition: Warning message: In max(panels$ROW) : no non-missing arguments to max; returning -Inf
I really have no idea how to fix this. Do need to create a cuffData object, if so how? Or is there a simpler fix?
Thanks all in advance. Kenneth.
