(numeric): Number of columns in the dataset.

Implements sanity check for the input data. This function is for internal use and is called
by the <code><a rd-options="" href="/link/dcem_train?package=DCEM&version=2.0.4" data-mini-rdoc="DCEM::dcem_train">dcem_train</a></code>.

Implements the Improved Expectation Maximisation EM* and the traditional EM algorithm for clustering
big data (gaussian mixture models for both multivariate and univariate datasets). This version
implements the faster alternative EM* that avoids revisiting data by leveraging the heap structure.
The implementation supports both random and K-means++ based initialization. Reference: Hasan Kurban, Mark Jenne,
