str(myposts)
head(myposts)
plot(myposts$ti,myposts$nC) #number of comments

You can also see the Rpubs document here http://rpubs.com/decisionstats2/plusser Now you can do text analysis and sentiment analysis on myposts$msg and do social media analysis on what makes people like what kind of content. 


For better results, use a google plus id (page or person) which has a lot of PUBLIC posts!
