Splitting data into multiple rows when using anti_sample=true

[martijnvv]

I run the following code with or without anti_sample:

cf <- dim_filter("dimension7","EXACT",campaign_name,not = FALSE)
fc <- filter_clause_ga4(list(cf))
gaDataFunnel_dev1 <- google_analytics_4(viewId, 
                                    date_range = c(dateStart, dateYesterday),
                                    dimensions=c("deviceCategory", "dimension7"), 
                                    metrics = c("uniquePageviews"),
                                    order = order_type("deviceCategory", "ASCENDING"),
                                    dim_filters = fc,
                                    anti_sample = TRUE)

The code with anti_sample=true returns the same values separated into two rows:

Without anti_sample=true, the table is no longer split into multiple rows:

This seems to occur only in the past few days. It didn't happen before.
I'm running version 0.3.0 of the package

Thanks - may I ask how many rows are in the tables you are fetching? Also the results of sessionInfo() just to check all dependency versions. You may want to try using latest version of googleAuthR from Github to see if that helps.

[martijnvv]

The table has 6 vs 3 rows (deviceCategory).
I just ran the same query after updating the googleAuthR version from github. Issue persists.

See sessionInfo() below:

Weird, ok thanks, will take a look.

Hi @martijnvv , I can't replicate this with the below code:

> dateStart <- Sys.Date() - 30
> dateYesterday <- Sys.Date() - 1
> cf <- dim_filter("source","EXACT","google",not = FALSE)
> fc <- filter_clause_ga4(list(cf))
> gaDataFunnel_dev1 <- google_analytics_4(viewId, 
+                                         date_range = c(dateStart, dateYesterday),
+                                         dimensions=c("deviceCategory", "source"), 
+                                         metrics = c("uniquePageviews"),
+                                         order = order_type("deviceCategory", "ASCENDING"),
+                                         dim_filters = fc,
+                                         anti_sample = TRUE)

Could you perhaps also report the message feedback when you set options(googleAuthR.verbose = 1) before running your call.

And also install the version of googleAnalyticsR from Github v0.3.0.9000, there was a bug with zero-rows in anti-sample calls that may have an effect.

Hi @MarkEdmondson1234 ,

I first updated to version 0.3.0.9000, that made no difference...
Below is the response to my query. Your query may not have this issue, because there is no unsampling of the data required in your request.

[MarkEdmondson1234]

@martijnvv The latest Github version now includes a aggregateGAData function that aggregates across dimensions, which is useful on its own, but I have also applied it to the results of anti_sample runs which should solve the above issue. Let me know if it works, in particular keep an eye on if a metric should be summed or averaged as this is performed by the library and not via the API as is done in other calls, so could be different and have strange behaviour (things like bounceRate, avgTimeOnsite etc.)

[martijnvv]

@MarkEdmondson1234 Consider that bug squashed. I haven't run any queries with averaged values or percentages, only absolutes.

Thanks!
