私はストリーミングAPIに関する質問にお答えできませんが、返信を扱う場合はthis helpful tutorialに基づいてどうでしょうか。おそらくそれを使って、ユーザーごとのリツイート数の代わりに特定のつぶやきに集中することができます。 posts hereのうちのいくつかがより有用かもしれません。
# get package with functions for interacting with Twitter.com
require(twitteR)
# get 1500 tweets with #BBC tag, note that 1500 is the max, and it's subject to mysterious filtering and other restrictions by Twitter
s <- searchTwitter('#BBC', n=1500)
#
# convert to data frame
df <- do.call("rbind", lapply(s, as.data.frame))
#
# Clean text of tweets

# Extract retweets
