How do you extract "eventDate" column from the database with bison()?

Example code:

download <- bison(species = "Strix occidentalis caurina", type = "scientific_name",
   count = 10000000)
bison.pts <- download$points
head(bison.pts)

try bison_solr intead. bison doesn't return date data

z <- bison_solr(scientificName = "Strix occidentalis caurina", rows = 10)
#> z$points$eventDate
#>  [1] "2017-05-17" "2014-06-15" "2014-06-15" "1996-01-01" "1996-01-01" "1992-01-01" "2000-01-01" "1980-11-05"
#>  [9] "2003-01-01" "1991-07-16"

bison_solr() does not allow me to download more than 10k points. Is there a way to not be limited by the number of points and be able to get the date of records?

try using the rows and start parameters. e.g,.

# records from 1 to 10
bison_solr(scientificName = "Strix occidentalis caurina", rows = 10)
# records from 10 to 20
bison_solr(scientificName = "Strix occidentalis caurina", rows = 10, start = 10)

important if you get to big numbers like 10000 to write them like 10000L to make sure they don't get turned into scientific notation which will not work when sent to USGS web service
