This book serves to show how functional programming and unit testing can be useful for the task of data munging. This book is not an in-depth guide to functional programming, nor unit testing with R. If you want to have an in-depth understanding of the concepts presented in these books, Data wrangling, sometimes referred to as data munging, is the process of transforming and mapping data from one "raw" data form into another format with the intent of making it more appropriate and valuable for a variety of downstream purposes such as analytics. A data wrangler is a person who performs these transformation operations.

Jun 05, 2014 · Data Munging. The next phase of a machine learning project involves a process called “data munging.” It is often the case where the data imported into the R environment is inconvenient or incompatible with machine learning algorithms, so with data munging (also known as data transformation) the data can be massaged into a more hospitable form. Data munging or data wrangling is loosely the process of manually converting or mapping data from one "raw" form into another format that allows for more convenient consumption of the data with the help of semi-automated tools. In other words, data wrangling (or munging) is the process of programmatically transforming data into a format that

To use H2O with R, start H2O outside of R and connect to it, or launch H2O from R. However, if you launch H2O from R and close the R session, the H2O session closes as well. The H2O session directs R to the datasets and models located in H2O. This following sections describe: installing R Data Wrangling with R. Data wrangling, which is also commonly referred to as data munging, transformation, manipulation, janitor work, etc. can be a painstakenly laborious process. In fact, its been stated that up to 80% of data analysis is spent on the process of cleaning and preparing data.
