I'm trying to get Tweets in R for specific date ranges. From what I've read, the following R code should work, but I get no results:
library(twitteR)
library(ROAuth)
searchTwitter('green', since='2013-03-01', until='2013-03-31',cainfo="cacert.pem")
However, this code does work, i.e. with a date range of the last few days.
searchTwitter('green', since='2013-06-01', until='2013-06-15', cainfo="cacert.pem")
Is it that we can only go back several days of tweets? Not months? How far back can we go?
The Twitter API will only let you go back a few days
