R user meeting: some basics

We will discuss and show several topics on basic level, such as: data exploration and basic plotting. The script will be placed on https://github.com/wageningen/RUsers#rusers shortly before the meeting.

If you have anything basic that we would like to be discussed, please sent it to r-users@wur.nl and we will see if we can include it!

Note that the Leeuwenborgh building is a bit outside the campus itself, in the direction of Wageningen city center.  See https://ssc.wur.nl/Handbook/Room/C0068
