Data import is done in 3 steps:


1 - Add a file and 2 - click Start to load (first tab)

3 - Click Next to move to the second tab:

<ul class="bb_ul">
<li class="bb_li">Select a file to import into R.
</li><li class="bb_li">Specify the import options.
</li><li class="bb_li">Click Import to load the data into R.
</li></ul>

The software then reads the file and automatically creates two other files of the form: 'your_login.txt' and 'your_login.RData'.

Your imported data will be available in these two forms in all the software.

To load another file, you must do the same operation and the old data will be deleted. At each start of RWSTHDA, the old imported data are deleted.


To refresh the list of files: Click File -> Refresh.
