TwitteR - Number of tweets from multiple locations

Hi Juho!

Hi all, I am new to R and TwitteR and would love to get some advice from
you.

I managed to get list of tweets containing word 'innovation' tweeted in
Helsinki with following script:

searchTwitter('innovation', n=10000, geocode='60.1920,24.9458,30mi',
since="2016-01-01", until="2016-05-31")

However, I was wondering is it possible to involve multiple locations to
script, so that the result would be number of tweets in each location.

For example, something like this:
Location Tweets
Helsinki 300
Berlin 400
Barcelona 500

Have your read the documentation ('?searchTwitter'). The argument 
'geocode' cannot be a list, only a single value.

A possible workaround could be to filter tweets based on geocode after 
you have received these. However, since your search pharse is rather ge 
general, you would receive a lot of "noise" as well.

One possibility would be to write a loop with three 'searchTwitter' 
calls with different geocodes. Here you could speed up the data 
collection by setting 'n' to e.g. 100 or 500.

You should, however, consider the fact that geocodes are often supressed 
by the user, so that you would most certainly get only a limited amount 
of tweets.

Another problem I faced is in setting the time span I would like to have
the count of tweets from. I tried to set the time span from the beginning
of this year to end of May, but it seems like I get only tweets from the
last week of May.

If I remember correctly this is not related to twitteR, but to the 
Twitter API itself. The API limits your search results to contain tweets 
from the last 7 days only.

HTH,
Kimmo
