WebDec 6, 2011 · Well, if I had to guess (and I do, since we have no idea what your data look like, and calling your data matrix is a very bad idea): you have more variables than units, so clusplot () can't use princomp () to create a reduced- dimension plot. You could roll your own using a different ordination method, or you could remove some variables from ... WebHowever, a better way to think about this is that if one of your SD's is 0, there is no correlation. In loose conceptual terms, a correlation is telling you about how one variable moves around as the other variable moves around. An SD of 0 implies that variable is not 'moving around'. You would have to have a vector of a constant, such as rep ...

WebI'm happy to announce that the 0.3.0 version of the zfit package is now on CRAN. The goal of zfit is to make it easier to use a piped workflow with functions that don’t have the “correct” order of parameters, by providing wrappers that expect the data to be the first parameter. So you can pipe data dplyr-style: cars %>% zlm( speed ~ dist ) Or using the new native pipe:
