either I found an R bug or I'm misinterpreting how this is supposed to behave:

We have a dataset called weights, with an R view called 'weight graph'. I load the dataset grid, then filter on subject.

I switch to the weight graph view by selecting 'weight graph' from the view button menu. I would have expected the R view to be filtered the same as my grid, but it is not. attached screenshot shows the R report screen, plus my URL which has the query.Id~startswith filter.

if i re-filter the data using the data tab for the R view, it becomes filtered.
