my beer froze while cold crash what affect does that have on the beer ? And on the yeast ?
 
Freezing being generally bad for yeast you might want to look at adding some yeast if you intend to carbonate in bottles.
Some yeast may have survived but adding yeast is cheap insurance agaist flat beer.
 
Depending on how long it was frozen you should be good. If it just turned to slush rather than frozen solid the yeast should still be viable with no off flavors. My understanding is freezing the yeast will cause them to rupture putting off flavors in the beer. But if they didn't actually freeze themselves and the beer just turned slushy they should have survived. I agree with sparkncode... can't go wrong with adding more yeast to be on the safe side if bottle conditioning.
