Location filter

[kavyanjalik]

Hello, Thanks a lot for your support with the R package. Wanted to ask if it is possible to set the location filter to download tweets only from selected countries? Thank you!

Hi

This is possible via the Query you enter. The only thing you need to keep in mind is that only small percentage of Tweets have geo-tagged information associated with them. Thus, relying only on geo-tagged Tweets alone might introduce some bias in your dataset.

You can do this by entering a search query with the longitude, latitude and the radius like this: The Radius has to be smaller than 25 miles according to twitters docu

library(RTwitterV2)

Bearer_Token <- ""

query <- '"New York" point_radius:[-73.942859 40.629653 10mi]'

tmp <- full_archive_search(token = Bearer_Token, search_query = query, n = 1500)

I will probably add a param for the search function soon which will make it easier to use this feature.

Ther are other possible ways to restrict the search to location with the following operators:

• place:"new york city OR place:seattle OR place:fd70c22040963ac7
• place_country:US
• bounding_box:[west_long sounth_lat east_long north_lat] (again box is not allowed to be bigger then 25mi x 25mi)

Thank you so much! Yes, I agree with the bias in the dataset, which I will keep in mind.

Added a new function (v0.2.1) to make it easier to search for tweets within a Country (place_country), point_radius and bounding_box.

• point_radius: checks if radius is smaller than 40 km (25 mi)
• point_radius: radius needs to be specified as an integer which is handled in kilometers
• bounding_box: checks if width and height of box are smaller then 40 km (25mi)
