I tried EBImage several years ago for another problem, but Bioconductor packages have some difficulties
to install in our network/firewall environment and I am not in a position to change it. It seems to me also an
overkill for such simple task.
jpeg and png seems to me a bit too much simple, without direct possibility to transform from rgb to grayscale
Anyway, I will give it a try.

Some possibilities: The EBImage package on Bioconductor; the jpeg and png packages read jpeg and png images.

I prepared some image processing routine which depended on package ReadImages. Basically I imported
image to R, changed rgb to grayscale, normalised an image made some selections and changed to image by imagematrix.
Recently I learned that this package was removed from CRAN and can not be used in R 3.0.0.
What options I have now to import image to R, change it to grayscale, make some computation or selection,
