Saving and loading objects¶
# In this example we create the two variables 'a' and 'b': a <- 1 b <- 1 # We save them in the data file "ab.RData" save(a,b,file="ab.RData") # We then remove the two variables: rm(a,b) ls()
# With then load the data file load("ab.RData") # and verify that the two variables are restored ls()
 "a" "b"
Downloadable R script and interactive version
The link with the “jupyterhub” icon directs you to an interactive Jupyter1 notebook, which runs inside a Docker container2. There are two variants of the interative notebook. One shuts down after 60 seconds and does not require a sign it. The other requires sign in using your ORCID3 credentials, yet shuts down only after 24 hours. (There is no guarantee that such a container persists that long, it may be shut down earlier for maintenance purposes.) After shutdown all data within the container will be reset, i.e. all files created by the user will be deleted.4
Above you see a rendered version of the Jupyter notebook.5
