CLR Transform Tool - Selection of columns/attributes of the input data #244

Open chudasama-bijal opened 3 weeks ago

chudasama-bijal commented 3 weeks ago

CLR Transform Tool (Transformations): There seems to be no option to select the attributes of input data for CLR transformation. Selection of columns to perform CLR transformation upon needs to be added as an input parameter.

@chudasama-bijal Do some other coda tools need a column selection parameter too? This requires changed to EIS Toolkit and it would be good to cover all coda changed at once

chudasama-bijal commented 3 weeks ago

@nmaarnio - These should have the column selection parameter: ALR, Inverse ALR, CLR, Inverse CLR, Single ILR, Single PLR, Pivot logratio.

It is not possible to test/run the coda transforms in the plugin without having an option to select the columns to be transformed. By default, it seems to run on all columns. Of course, a vector file with only numeric data can be created, but that's not how the input data will always be for these tools.

For Pairwise Log ratio transform, there could be an additional option to implement this simultaneously for multiple column pairs. For instance, select columns, and compute all the possible pairwise logratios, for different numerator-denominator combinations.

Okay. So quite many changed are needed for both EIS Toolkit and EIS QGIS Plugin. I don't know if I have time to take this task on my plate, especially the toolkit-side work.

@em-t - try to look into this when possible. https://github.com/GispoCoding/eis_toolkit/issues/447
