This is because we assigned the output to the new variable z.Mine Çetinkaya-Rundel is Professional Educator and Data Scientist at RStudio as well as Senior Lecturer and Associate Professor. If you rerun the chunk you will no longer see the output. We can also assign the result to a new variable like so: pane now displaying the variables you created. Note how running the chunk results in the Environment.
If you rerun the chunk, you will get the same output as before, i.e. We can also work with variables, try to change your chunk as follows (Note the special assignment operator <-, simply meaning "put the number 2 into the variable "x"): Now, if you hit the knit button again, you will se your code chunk along with the output.
Try to write 2+2 in the chunk, so that it looks like so:Īnd then click the little green play button in the upper right corner of the chunk, this will give you the chunk output (Note that the simply denotes, that one value was returned) This will give you an empty chunk, which looks like so You can create a new code chunk by hovering above code in the menu, clicking and selecting Insert Chunk (or use the short-cut above). In the Sandbox section you created, complete the following to get a feel for rmarkdown: Note, section are not wrapped in chunk-tags.
