This post was inspired from Jon Tennant's post on his blog (here). He was talking about the number of papers on paleontology field published in PLOSone. His post was mainly based on his code using `rplos` package (Github repo/CRAN repo) from `ropensci` community. Jon's post was kind of fire up my R life again, especially in the field of text mining. So in this post, I will connect this original post with my research about analyzing biodiversity of Cikapundung riverbank area (here/Figshare).  
This post is going to tap paper data from PLOS and PubMed Central (PMC) using R, RStudio, rplos package, and rplotly package. So how it goes:
Then I write some code following Jon's code from his blog and add it with some my own.
