Has someone tried to use mclust package function emclust() to fit a
mixture of gaussian model for a relatively large dataset?
By "large", I specifically have in mind a data set with 50,000
observations and 23 dimensions. My machine has 750M memory and 500M swap
space. When I tried to use emclust on the dataset, I consistently get
messages such as "Error: cannot allocate vector of size 1991669 Kb". In
other words does this mean that R is trying to allocate almost 2000Mb
space? Should this be considered abnormal?
