[R]To delete a dataset from the environment

How can I delete a dataset from the environment if it is not used anymore in Rstudio?

n RStudio, you can remove a dataset from the environment using the rm() function. If you want to remove a dataset named mydata, for example, you would use:

R 复制代码
rm(mydata)

This will remove the mydata dataset from the environment. If you want to remove multiple objects, you can specify them as a list inside the rm() function:

R 复制代码
rm(mydata1, mydata2, mydata3)

You can also remove all objects from the environment with:

R 复制代码
rm(list = ls())

This will remove all objects except functions and the base packages. If you want to remove everything, including functions and packages, you can use:

R 复制代码
rm(list = ls(all.names = TRUE))

However, be cautious when using rm(list = ls(all.names = TRUE)) as it will remove all objects, functions, and packages, which can lead to unexpected behavior.
