Without a working example, only a guess is possible.

Try dropping the cbind().  It is not needed because data.frame takes a set
of vectors directly.
The cbind could easily be changing the class of some of your arguments.

results <- data.frame
(trialnum1=trialnum1,SimOR01=sim.or.x0x1,Simlogor01=sim.lor.x0x1,

Simlogorse01=sim.lor.x0x1se,trialnum2=trialnum2,SimOR02=sim.or.x0x2,

Simlogor02=sim.lor.x0x2,Simlogorse02=sim.lor.x0x2se)
