R++ est un logiciel d’analyse statistique haute performance. Simple, rapide, efficace. Pour mettre les statistiques à la portée de tous.

Typing

 

All statistical programs make mistakes in typing some variables. R++ has a type viewer so that you’re not stuck with wrong parameters during analysis.

 

 

In the viewer all the types are matched with a colour:

  • Turquoise for numerical variables
  • Violet for nominal variables
  • Blue for ordered variables
  • Yellow for logical variables
  • Green for integer variables

 

 

 

 

 

 

When the type is not correct you can go to the configuration menu and change it in a simple click.

I this example R++ thinks the French department number are integer variables. It’s meaningless, you can’t average departments out (e.g. 31 = Haute-Garonne, 91 = Essonne). To fix it, just pick “Nominal” in “Department” column.

 

 

 

 

Sometimes a type is not correct because some of its

levels are not correct.

For instance when there is “zero” instead of “0” the program recognises a nominal variable. You can change the type with the integer button. R++ highlights the incoherent levels in red at the top of the column. Hence you can spot and fix quickly them.

 

 

 

 

 

Statistical programs always recognise ordered variables as nominal variables. With R++ you can see the levels, drag & drop to order them, click the “ordered” button and confirm. The changes are made!

 

 

 

Once you’ve changed the format for a variable you can duplicate it to other variables with a copy and paste.

 

 

As always, all the actions are available in the code menu.
