'steemr' is an open source R package for playing with Steem data in R environment. It is used to download, post process, analyze,  and visualize Steem data on the basis of the powerful statistic power of R. 

### New Features

#### What features did I add?

- I have submitted steemr to CRAN and now it is [available](https://CRAN.R-project.org/package=steemr). Users can install steemr directly from CRAN:

  ```
  install.packages('steemr)
  ```

  

- Users can use `method = 'appbase_api'` to download Steem data from AppBase API:

  ```
  posts <- post_id('dapeng', method = 'appbase_api')
  ```

  

- A new powerful function `hourrose()` was added to plot a diagram of an ID's active hours in a day based on the post or comment time.

  ```
  hourrose(my_df = posts, col_time = 'created')
  ```

  This 24-hour clock shows the active hours of an ID.  Users can even choose whether to display another parameter, such as vote number on these posts. Here is a screenshot of plotting such a image in RStudio IDE.

  More feature of this function can be found in the help documentation:


  ```
  help(hourrose)
  ```

- Although SteemData is gone, I still added the query method from steemdata.com. I wish SteemData could come back some day. I love it.
- The documentation has been improved.
- Some minor literal chagnes.

#### How did I implement them?
I added the AppBase API option to the `id_info()` function and `post_id()` function with the support from ' kharoof/steemR' repo. 

I added the queries for SteemData with the R mongolite package and added the options that users can choose the server.  

I added a new function `hourrose()` originated from a windrose plotting method but tailored for Steem data.

All these changes can be found in 'R/steemr.R'.
