How can I label a dataset

[niugg2020]

I am new to R. I am wondering how to label a dataset, like to label ADSL as " Subject Level Analysis Dataset"
Thanks

Check here. Maybe you will find answer:

Thanks a lot. I checked the link and it is used for label variables or values. I have no problem to labeling variable or value. But I did not find a way to label data-frame or tibble or dataset.

what would it mean to 'label' a dataset, and in what context is that useful ?
do you perhaps just mean the name that its known by ?
you could indeed add arbitrary attributes, that you could access ... but is this worthwhile ?
attributes wont often come along for the ride when you use transformations, so they can be pretty fragile...
unless you want to get into making your own classes, but I think this would open up a big can of worms.
Something I do very occasionally is to keep related objects in a common list.

mydata <- head(iris)

attr(mydata,
     "mylabel") <- "This is to document that this data.frame was made by head(iris)"

mydata

attr(mydata,"mylabel")

attributes(mydata)

mydata2 <- select(mydata,
                  Petal.Length)

mydata2
attr(mydata2,"mylabel")

mydata2 <- mydata
attr(mydata2,"mylabel")
mydata2 <- select(mydata2,
                  Petal.Length)
attr(mydata2,"mylabel")



mydata3 <- list(Note="The data.frame came from head(iris",
                df = head(iris))

mydata3

Thanks you very much. I checked other SDTM dataset. Inside, they have $label attribute, and it should be similar to your example 'mylabel'.
