Exellent article, thank you.
For those of you that just hate creating views or would like to keep experimenting with different sql queries and have windows connection rather than a SQL ones, the following my help:

SQLconnection<-odbcDriverConnect("Driver=SQL Server; Server=MyDummyInstance\\BI_DEV; Database=AdventureWorksDW2012; trusted_connection=true;")

salesData<- sqlQuery(SQLconnection, "
select
sales.ProductKey,
p.ProductSubcategoryKey,
ps.EnglishProductSubcategoryName,
p.EnglishProductName,
sales.SalesTerritoryKey,
t.SalesTerritoryRegion,
sales.CustomerKey
from dbo.FactInternetSales as sales
inner join dbo.DimProduct as p on p.ProductKey = sales.ProductKey
inner join dbo.DimProductSubcategory as ps on ps.ProductSubcategoryKey = p.ProductSubcategoryKey
inner join dbo.DimSalesTerritory as t on t.SalesTerritoryKey = sales.SalesTerritoryKey;
")

odbcClose(SQLconnection)


The are some issues with the code (some missing parenthesis and some reference to data frame or variables that don't exist such as the product_contributions one).

Very nice - thank you for adding that Smile

Hi Nick,

Thanks for the tutorial. Great to see someone putting effort to share their knowledge.

Just a little hickup.
below variables are not assigned for last graph.

- product_contributions
- by_region_trimmed

I am getting error :
> by_region_filter<- with(majorSalesData, table(SalesTerritoryRegion, ProductKey))
> results_filters <- CA(by_region_trimmed, graph = FALSE)
[color=#f00]Error in is.table(X) : object 'by_region_trimmed' not found[/color]
>

I look forward to more of these tutorial.

Thanks,
Yogs

Hi Nick,

I enjoyed this article very much. I am an Analysis Services user, but I put together some (much simpler) R examples for our R users to access our Data Warehouse. This model is spot on for SQL Server 2012 and 2014.

I am about to build some examples using 2016 CTP3.1 embedding the R calls in SQL scripts. Any thoughts about how you take advantage of the embedded model for the types of analyses in your examples?

Thank you for sharing!

Chris

Great article and timely as I am currently in the process of explaining the power of R relative to what is currently in the MSBI stack. I might add the built-in visualizations as a differentiator compared to the SSAS basket analysis solution. I've been challenged to investigate options in SSAS, but my intuition tells me that it would be futile given the current flexibility of R, the direction of 2016 and the inevitable granularity required to conduct such analyses.

Hi Yogs, thanks for finding these Smile

I think that 'product_contributions' should be replaced by 'strength'. And 'by_region_trimmed' should be 'by_region_filter'.

Cheers,
Nick
