R help - Feb 2013 - package ReadImages

Dear all

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, change it back to image and plot for visual
inspection.

Thanks
Petr

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

Petr,

Another program that may be useful is ImageJ which has a great many
useful analytic plugins.  The program is written in Java and it
supports a good many different image file formats.  You should also be
able to use Octave to normalize an image.
