Aperture Reading Blank

I have the Pentax Kr and i have a question about a blank aperture reading that I get.
When I am taking pictures the F stop is reads R---.
I attribute this to the fact that I am using a manual lenses. but If I not mistaken I have read about others that have made adjustments for manual lenses that may have correct this.
When I use the Pentax Digital Camera Utility 4 and check out pictures the image information leaves the F stop blank also.
Does this mean that i will physically have to compile the F stop information myself for each exposure?

Thank you,

Yes, because the camera has no way of knowing what the aperture setting is.
