R Package "cleandata"

A collection of functions that work with data frame to inspect and manipulate data; and to keep track of data manipulation by producing log files.

Available on CRAN: https://cran.r-project.org/package=cleandata

Demonstration: Wrangling Ames Housing Dataset

I planned to keep writing new demos and linking them in this Readme file.

New in V0.3.0

• Made parameter 'log' able to take value from a 'log_arg' variable in the parent environment (dynamic scoping) of a function
  • The old way of assigning value to 'log' is also supported
  • 'log' is the parameter to control producing log files
