[BioC] EBImage crop failure

[Michael Cole]

Using the latest version of EBImage and ver 8:6.6.9.7-5 of ImageMagick (debian 
package) several EBImage operations fail.

In particular, cropping an image with:
a<-readImage("xxxxxxxx")
a[1:120,50:120] # fails with "incorrect number of dimensions"]

I can get cropped images by doing:
a[1:120,50:120,1] # display gives correct region with a red mask
a[1:120,50:120,c(1,0,0)] # display gives correct region with a red mask
a[1:120,50:120,c(1,0,1)] # display gives correct region with a yellow mask
a[1:120,50:120,c(1,1,1)] # display gives correct region as grayscale
a[1:120,50:120,c(0,1,1)] # display gives correct region with a yellow mask

and so on.

Has there been a change in EBImage that is not reflected in the documentation?

I am trying to build histograms for each color channel to build classification 
models.


Thanks,

Michael
