delete a variable in r

To delete a variable in R, you can use the rm() function followed by the variable name you want to delete. For example, if you want to delete a variable named my_var, you can use the following code:

main.r
rm(my_var)
11 chars
2 lines

You can also delete multiple variables at once by passing their names as a vector to the rm() function. For example:

main.r
rm(my_var1, my_var2, my_var3)
30 chars
2 lines

You can check if the variable has been deleted by trying to access it. If the variable has been deleted, you will get an error message saying that the object cannot be found.

It's important to note that deleting a variable doesn't necessarily mean that the memory used by the variable is immediately freed. R uses a method called "garbage collection" to determine when to release memory that is no longer being used.
