MinT: Error in if (!is.symmetric.matrix(x)) stop("argument x is not a symmetric matrix") : missing value where TRUE/FALSE needed about hts HOT 1 OPEN

@earowang I found that this error may be caused by the input residual of function MinT() has 0， corm <- cov2cor(covm) in function shrink.estim() return this error, Is <- sqrt(1/diag(covm)) in function cov2cor(covm) return Inf element。Is there any method can solve this problem? Since 0 in residual may occur in the real world data sets.
