Jupyter notebooks are cool, but they are kind of mysterious in terms of how they work. For example, recently the R kernel started crashing whenever I opened a new R notebook. I finally found a note in a local document that said, "If your R kernel keeps dying, you may have to update pcre by executing 'conda update pcre'." I had never heard of pcre, but I updated it and the R kerel started working again. Go figure... I am really excited about using R Notebooks.
