It would have helped a lot if you had offered outout of: str(dataset)
I don't use fix() so I'm not sure I help you there. I do notice in looking at
the documentation that the function may return a list of dataframes rather than
just a dataframe, so perhaps you need to extract the dataframe object. (Just a
guess.)
I generally look at my files with names(), and Hmisc::describe() and use
table() for the factor or character values that I expect to have manageable
numbers of discrete categories. (Using `fix()` to edit gigabyte sized objects
is the way to madness.) You should probably read the Posting Guide because you
are failing to mention that the sasxport.get() function is part of the Hmisc
package. If you want to get rid of your attributes (which is where the labels
are stored) then the attr() function should allow you to NULL them out:

[1,] 1 3 5 7 9
[2,] 2 4 6 8 10

[1] 2 5

[1] 1 2 3 4 5 6 7 8 9 10
It also appears the there is a `label<-` function, so you could probably use
that to NULL them out.
