删除从 R 中的 RData 文件加载的变量

Question

Suppose I saved two variables:

x <- rnorm(5)
y <- letters[1:10]
save(x, y, file = "MySavedList.RData")
rm(x,y)

Later, I want to load this saved file ( MySavedList.RData ) and after using these variables I want to remove only the variables that are loaded from MySavedList.RData . All of the remaining variables in the environment should be intact. Something like this:

load(file = "MySavedList.RData")
...
rm("Variables loaded from MySavedList.RData")

I don't want to load these files into a new environment ( like this post ), or create a variable that holds the variable names when I first save the variables.

Answer 1

Would something like this work for you?

theloadedobjects <- load(file = "MySavedList.RData")
...
rm(list=c(theloadedobjects, "theloadedobjects"))
