This idea arose recently when working specifically with the Association Analysis tool, but I have a feeling that other predictive tools could benefit as well. I was trying to run an association analysis for a large number of variables, but when I was investigating the output using the new interactive tools, I was presented with something similar to this:
While the correlation plot draws your high to high associations, the user is unable to read the field names, and the tooltip only provides the correlation value rather than the fields with the value. As such, I shifted my attention to the report output, which looked like this:
While I could now read everything, it made pulling out the insights much more difficult. Wanting the best of both worlds, I decided to extract the correlation table from the R output and drop it into Tableau for a filterable, interactive version of the correlation matrix. This turned out to be much easier said than done. Because the R output comes in report form, I tried to use the report extract macros mentioned in this thread to pull out the actual values. This was an issue due to the report formatting, so instead I cracked open the macro to extract the data directly from the R output. To make a long story shorter, this ended up being problematic due to report formats, batch macro pathing, and an unidentifiable bug.
In the end, it would be great if there was a “Data” output for reports from certain predictive tools that would benefit from further analysis. While the reports and interactive outputs are great for ingesting small model outputs, at times there is a need to extract the data itself for further analysis/visualization. This is one example, as is the model coefficients from regression analyses that I have used in the past. I know Dr. Dan created a model coefficients macro for the case of regression, but I have to imagine that there are other cases where the data is desired along with the report/interactive output.
