How can I load the SparkR, sparklyr, and dplyr packages in a Databricks R notebook?
To load the SparkR, sparklyr, and dplyr packages in a Databricks R notebook, you can use the `library()` function for each package. Here is an example code cell that you can run in your notebook:
```r
library(SparkR)
library(sparklyr)
library(dplyr)
```
This code will load the necessary packages and make their functions available for you to use in your notebook. Note that you do not need to install these packages, as they are included in the Databricks Runtime.
