r - depmixS4 HMM拟合中出现NA/NaN/Inf错误时如何继续循环？

Question

代码：

for(j in 1:100){......     
for(k in 1:20) {
        fit.mod = fit(mod)
        if(AIC(fit.mod) < best) { best_model = fit.mod 
        best = AIC(fit.mod)
        } 
      fit.mod <- best_model
........}

当错误

Error in fb(init = init, A = trDens, B = dens, ntimes = ntimes(object),  : 
  NA/NaN/Inf in foreign function call (arg 10)

发生，循环自动停止。我试过了

if(is.na(fit.mod)){next}

和

if(!identical(fit.mod@message,c("Log likelihood converged to within tol. (relative change)"))){next}

但循环仍然停止。有没有一种方法可以忽略此错误并继续循环？提前致谢！
