Handwritten digits with `flexmix`

The digits_sample_2 is a data frame that has 478 observations, each of them representing a binary image of a handwritten digit formed by 16x16 pixels. The aims of this exercise are (1) to explore these data, (2) to fit a Bernoulli mixture model using flexmix and (3) to analyze the resulting clusters.
