Besides being a programming language with a huge number of libraries containing statistical techniques, it can (and should!) also be used for its graphical libraries (e.g. ggplot2).

Recently, it became possible to integrate a user’s ‘R Environment’ with regards to these graphical libraries into a SAP Analytics Cloud story by using the ‘SAP Analytics Could R Visualization’-feature.  

To visualize this new feature, a simple example will be used: a dataset with 40 months (01.2015 till 04.2018) of Sales/Revenue data in combination with 8 months of calculated forecast (05.2018 till 12.2018) is used.

Having created a new basic Model with the above-mentioned 48 months of data:

We can now add the R Visualization within our Canvas page of a new Story:

Which will generate the following frame on the Canvas:

In the ‘Builder’-framework you see two important options:

• Input Data: to import the data into the R Visualization;

• Script: to use the R Script Editor, which applies the R Script on the imported data.

After having imported the data, using the ‘Add Script’-functionality will give the following consoles to work with:

Where:

• Editor: R Script should be incorporated here;

• Console: displays what is being executed (either successfully, or else it will display error messages);

• Environment: additional information, such as the name of the imported dataset;

• Preview: preview of the results of the R Script that has been added in the Editor framework.

When starting to add R Script in the Editor, there is an auto-complete wizard, just like in the R Studio for example:

Please note that in general you will of course start with the library( …) statements, to initialize the R Script packages that are installed by default. But, it is also possible to just use simple statements, such as ‘plot(…)’:

Whereas changing the ‘x = dataset2’-statement to ‘x = dataset2$MontQ’ would result in the following error:

…As the ‘MontQ’-dimension of course not exists in the dataset2-model.

Adding some additional lines of code (e.g. lines, color and title):

Where executing will result in the following R Visualization:

Which is of course not the prettiest Visualization, but, surprise me yourself with something exciting!
