...Windows) I get the following note: . assetsMeanCov: no visible binding for global variable 'scaleTau2' . I'll try to explain why with a minimal example. Let's have a look at the following function: assetsMeanCov <- function(x, method = c("cov", "MCD", "OGK"), alpha = 1/2, sigmamu = scaleTau2, ...) { if (method == "cov") {cov(x, ...)} if (method == " MCD") {robustbase::covMcd(x, alpha = alpha, ...)} if (method == " OGK") {robustbase::covOGK(x, sigmamu = substitute(sigmamu), ...)} } where robustbase is ment...

In the robust library of S+, it is possible to compute Rocke's constrained M-estimator of scatter and location. Can't find anything within R that does the same thing. Can someone tell me whether any package exists for computing it? Thanks. Rand Wilcox Professor Dept of Psychology University of Southern California Los Angeles, CA 90089-1061 FAX: 213-746-9082
