Hi, Daniela.

When you are having problems, it is best to include a reproducible
example, the output of sessionInfo(), as well as relevant error
messages.  Also, you'll benefit from carefully reading the
documentation for each function that you are using.  The code below
produces a heatmap with 104 rows, readable row and column names, a
key, and no dendrogram, as an example.
