You can use CCP4 programs SFALL and RSTATS to do this.

[1] You need to calculate the F and SigmaF from I and SigmaI from some
    programs.  In CCP4, you can use TRUNCATE to do this.
[2] Use SFALL to calculate Fcalc and Phicalc from your model structure.
[3] Use RSTATS to determine an R-factor between Fobs and Fcalc.

Note, you have to have your F's and SigmaF's in the MTZ format which is understable to CCP4 programs.
