Mask output of The following objects are masked from after calling attach function

Question

I wonder if there is a way to mask the long list output of The following objects are masked from XXX position 11   every time I call attach   function

User · Answer

You actually don t need to use the attach at all  I had the same problem and it was resolved by removing the attach statement

User · Answer

You use attach without detach - every time you do it new call to attach masks objects attached before  they contain the same names   Either use detach or do not use attach at all  Nice discussion and tips are here

It may be  better  to not use attach at all   On the plus side  you can save some typing if you use attach   Let s say your dataset is called mydata and you have variables called v1  v2  and v3   If you don t attach mydata  then you will type mean mydata v1  to get the mean of v1   If you do attach mydata  then you will type mean v1  to get the mean of v1   But  if you don t detach the mydata dataset  every time   you ll get the message about the objects being masked going forward   Solution 1  assuming you want to attach     Use detach every time  See Dan Tarr s response if you already have the data attached  and it may be in the global environment several times    Then  in the future  use detach every time    Solution 2  Don t use attach   Instead  include the dataset name every time you refer to a variable   The form is mydata v1  name of data set  dollar sign  name of variable    As for me  I used solution 1 a lot in the past  but I ve moved to solution 2   It s a bit more typing in the beginning  but if you are going to use the code multiple times  it just seems cleaner

If you look at the down arrow in environment tab  The attached file can appear multiple times  You may need to highlight and run detach filename  several times until all cases are gone then attach newfilename  should have no output message
