Dear R-team, I am using HPbayes package, specificaly hp.bm.imis function in it. When I run the function it sometimes gives this error Error in eigen(m, only.values = TRUE, symmetric = TRUE) : infinite or missing values in 'x' even though in my data there isn't any missing values or infinte values. The weird thing though is that when I run the function again sometimes it changes the error to be Error in like.resamp(K = K, log.like.0 = log.like.0, opt.cov.d = opt.cov.d, : argument "K" is missing, with no default even though I defined the K in advance. I don't know what is the problem and why it gives different error at each run. Also, when I expanded the function it gave another error in MVN!!! Thank you for your time and patience.
