remove dataset in environment in r

To remove a dataset from the environment in R, you can use the rm() function followed by the name of the variable that you want to remove. For example, if you have a dataset called mydata, you can remove it from the environment using the following command:

main.r
rm(mydata)
11 chars
2 lines

Alternatively, you can also remove multiple datasets at once by providing a vector of variable names to the rm() function. For example, if you have two datasets called mydata1 and mydata2, you can remove them both using the following command:

main.r
rm(mydata1, mydata2)
21 chars
2 lines

Note that once a dataset has been removed from the environment using rm(), it cannot be recovered unless it has been saved to an external file. Therefore, it is recommended to use this command with caution and make sure that you do not accidentally remove any important datasets.
