I love massive open online courses such as provided on Coursera and edX. So I enrolled in the Data Analysis for Genomics course on edX. I am not alone there as seen from this posting on FreshBiostats.
I was shocked when I took the Pre-Course R self-assessment, imagining this would be easy, click through some answers and done. But I read these questions “Use match() and indexing…” and “How would you use split() to…”. If I ever used match() and split() it must have been ages ago. Hat to use the help just to know what they did.
So, I am wondering how may other basic R functions I have forgotten. I remember searching for quite some time because I forgot ave(), must have forgotten that 3 or 4 times. Same for Reduce().
I am almost certain I have programmed the wheel once or twice, not knowing it is in a package sitting right in my computer. Hence even though boring, I find it a good thing to get down to basics again, but it would be nice to run these lectures at 1.5 speed.
Then the course suggests RStudio
where my preference is Eclipse
. It is probably good to be out of my comfort zone but I don’t expect my taste to change.
Finally, programs come in markup language (.Rmd files). I am curious to learn if they manage to make added value out of that. Let week 2 begin.
