This repository was createt using the web interface of github.com. The follwing commands have been executed locally in order to get the Repo to its current state (SHA: 7d70181023d246313af6fcf91c274eeab5872b35):

git init
git remote add origin git@github.com:carlschmidt26/oc_Data_Science_SS19.git
### changed the .gitignore file to ignore *.csv and*.pdf files ###
git add *
git commit -m "initial commit"
git push -u origin master
### created a new R project in the local directory of the Repo ###
git add Meteolytix.Rproj
git commit -m "Created new R project"
git push

Note that this README.md file has been created afterwards in the local directory (the local branch is called master) and has been pushed subsequently (after calling git add README.md and git commit -m "added README.md") to the remote branch, which is called origin by git push origin master.
Equivalently one could simply use git push because the first git push was called using the -u option setting the upstream(remote) branch of origintomaster`.
