Reshape

Reshaping the IT world

During my university time I worked on the IT help desk for a while. One day I received a call from a professor, who said that his printer had stopped working. So I asked him, if there was a message on the display and if he could read it to me. “Oh yes”, he said, “it says: ‘Load A4 paper.’” Rachel King quotes a study by Cisco on ZDnet, which believes to have found out that college students and young employees under the age of 30 would rather take a lower salary than having no social media freedom, device flexibility and work mobility.

The reshape function

The other day I wrote about the R functions by, apply and friends, which allow me to operate on subsets of data. All those functions work nicely, if the data is given in the right format. More often than not it isn’t and I have to reshape the data beforehand. Thus, time to discuss the reshape function. I will focus on the reshape function in base R, and not the package of the same name.
