I installed swirl package in R studio console and I started learning R programming. After completing a chapter I closed R studio. I didn't save the workspace while quitting the R studio.
After a day I started R-Studio again and ran swirl() command in the console. The R-Studio gave this error - "Error: could not find function "swirl""
Do I need to install the package everytime in R studio? Doesnt it store in R ? Pls help.
you should first type the command library (swirl). That will load the library in the namespace and allow you to use its functions.
