Since the reference management software (such as 'Zotero', 'Mendeley') exports Bib file journal abbreviation is not detailed enough, the 'journalabbr' package only abbreviates the journal field of Bib file, and then outputs a new Bib file for generating reference format with journal abbreviation on other software (such as 'texstudio'). The abbreviation table is from 'JabRef'. At the same time, 'Shiny' application is provided to generate 'thebibliography', a reference format that can be directly used for latex paper writing based on 'Rmd' files.

Scientific journal numeric formatting policies implemented in
  code. Emphasis on formatting mean/upper/lower sets of values to pasteable
  text for journal submission. For example  c(2e6, 1e6, 3e6) becomes
  "2.00 million (1.00--3.00)".  Lancet and Nature have built-in
  styles for rounding and punctuation marks.  Users may extend
  journal styles arbitrarily. Four metrics are supported;
  proportions, percentage points, counts and rates.  Magnitudes for
  all metrics are discovered automatically.

Implements under/oversampling for probability estimation.  To be
    used with machine learning methods such as AdaBoost, random forests, etc.

Tool for diagnosing table joins. It combines the speed of `collapse`
     and `data.table`, the flexibility of `dplyr`, and the diagnosis and features 
     of the `merge` command in `Stata`.

Read Japanese city codes (<https://www.e-stat.go.jp/municipalities/cities>) 
    to get city and prefecture names, or convert to city codes at different 
    points in time. In addition, it merges or splits wards of designated cities
    and gets all city codes at a specific point in time.

This package provides an easy and simple way to read, write and display bitmap images stored in the JPEG format. It can read and write both files and in-memory raw vectors.

A Joint PENalty Estimation of Covariance and Inverse Covariance Matrices.

Provides functions for grid square codes in Japan
    (<https://www.stat.go.jp/english/data/mesh/index.html>).
    Generates the grid square codes from longitude/latitude, geometries, and 
    the grid square codes of different scales, and vice versa.
