Hi Kelly, You seem to be testing the two "years" independently, so here is a possible solution: npg<-16 futility1<-futility2<-psignif1<-psignif2<-nrep<-0 while(!futility1 && !futility2 && !psignif1 && !psignif2 && nrep < 1) { control_respond1<-sum(runif(npg,0,1) < 0.05)

[R] trouble with exiting loop if condition is met

I am working on a clinical trial simulation with two groups, treatment and placebo, and the outcome is dichotomous (recovery or no recovery) . I would like to stop my loop if either of my conditions are met: 1) futility - there are no responses to treatment in the treatment group. 2) the p-value

[R] Unable to return gmtoff from as.POSIXlt without converting date string to as.POSIXct first

Is it possible for someone to explain what is going on here? I would expect that `as.POSIXlt` would be able to accept `datestring` and return all the elements without having to convert it using `as.POSIXct` first. Do `as.POSIXlt` and `as.POSIXct` do different things with the `tz` arg? datestring
