The arrays generated by make-series are limited to 1048576 values (2^20).Here are two options using a) filter and b) slice from dplyr. In this case there are no duplicated minimum values in column c for any of the groups and so the results of a) and b) are the same. If there were duplicated minima, approach a) would return each minima per group while b) would only return one minimum (the first) in each group.. a) > data %>% group_by(b) %>% filter(c == min(c)) # ... Once the file is uploaded, the all_datasets file will ne 5. if you want to have LocationId as one of the aggregation keys, you should include it in the call to summarize, as follows: | summarize ErrorCount = count() by UserId, LocationId.
