I'm working with SafeGraphR read_many_patterns() and seeing something unexpected. Can someone help?

@Nick_H-K_Seattle_University I’m working with SafeGraphR read_many_patterns() with gen_fips=TRUE. It creates the state_fips column but not the county_fips column that I was also expecting. Do you know why this would happen?

What does your “by” argument look like? If you’re aggregating to the state level, it will drop the county indicators

3

my “by” is NULL right now, so not aggregating at all.

4

My end goal is to expand the visitor_home_cbg column and sum over the home cbgs, but I couldn’t get read_patterns() to run with expand_cat = "visitor_home_cbg" so I left that out for now.

                                  gen_fips = TRUE,
                                  filter = 'state_fips == 17',
                                  naics_link = IL_parks,
                                  post_by = FALSE,
                                  start_date = c(rep("2018-01-01",4)),
                                  select = c('safegraph_place_id','raw_visit_counts', 'raw_visitor_counts','visitor_home_cbgs','date_range_start','date_range_end'))```

Ah, I think I know what’s happening. I’ll fix that today. In the meantime, as long as you’re saving the poi_cbg variable, after loading the data you can do

DT[, c(“state_fips”, “county_fips”) := fips_from_cbg(poi_cbg)]

Where DT is the name of the data object you saved your read_many_patterns call as

Ok, thanks

Should be fixed now if you redownload SafeGraphR

Also changed the post_by default to be !is.null(by) so you shouldn’t need to specify post_by = FALSE for your by = NULL call.
