Hi Everybody, Thanks in advance for your help. This is my first time using the foreach statement and I cant get it to work properly so here is what i have
test<-function(){ repeat { cand2[l-1]<-rinvgamma(1,phi,lambda[l-1]) q2<-dinvgamma(cand2[l-1],phi,lambda[l-1]) p2<-cand2[l-1]^-1.5*exp(-y[l]^2/(2*cand2[l-1]))*exp(-((log(cand2[l-1])-mu_t_cand[l-1])^2)/2*sigmasq) ratio<-p2/(c[l-1]*q2) if (runif(1)< ratio) {break} } f2[l-1]<-min(p2,c[l-1]*q2) }} foreach(l=2:(n-1),.combine=c,.packages='MCMCpack',.options.nws=li st(chunkSize=250)) %dopar% test() even though i've created the array earlier called cand2 when i run this code i get the error object "cand2" not found. What I'm trying to do is the rejection method for my cand2. i need cand2 and f2 as vectors as output both of length l-2 in the correct order. if i do a for loop as normal it works perfectly. Any ideas?
