Quickly and easily create codebooks (i.e. data dictionaries) directly from a data frame.

Logic game in the style of the early 1980s home computers 
    that can be played in the R console. This game is inspired by 
    Mastermind, a game that became popular in the 1970s.
    Can you break the code?

Includes several classifications such as International Statistical Classification of  Diseases and Related Health Problems 10th Revision (ICD10),  Anatomical Therapeutic Chemical (ATC) Classification,  The International Classification of Diseases for Oncology (ICD-O-3), and  International Classification of Primary Care (ICPC). Includes function that adds descriptive label to code value.  Depending on classification following languages are available: English, Finnish, Swedish, and Latin.

Data analysis often requires coding, especially when data are collected through interviews, observations, or questionnaires. As a result, code counting and data preparation are essential steps in the analysis process. Analysts may need to count the codes in a text (tokenization and counting of pre-established codes) and prepare the data (e.g., min-max normalization, Z-score, robust scaling, Box-Cox transformation, and non-parametric bootstrap). For the Box-Cox transformation (Box & Cox, 1964, <https://www.jstor.org/stable/2984418>), the optimal Lambda is determined using the log-likelihood method. Non-parametric bootstrap involves randomly sampling data with replacement. Two random number generators are also integrated: a Lehmer congruential generator for uniform distribution and a Box-Muller generator for normal distribution. Package for educational purposes.

Tools for analyzing R expressions
  or blocks of code and determining the dependencies between them.
  It focuses on R scripts, but can be used on the bodies of functions.
  There are many facilities including the ability to summarize  or get a high-level
  view of code, determining dependencies between variables,  code improvement
