This book is written for statisticians, data analysts, programmers, researchers, teachers, students, professionals, and general consumers on how to perform different types of statistical data analysis for research purposes using the R programming language. R is an open-source software and object-oriented programming language with a development environment (IDE) called RStudio for computing statistics and graphical displays through data manipulation, modelling, and calculation. R packages and supported libraries provides a wide range of functions for programming and analyzing of data. Unlike many of the existing statistical softwares, R has the added benefit of allowing the users to write more efficient codes by using command-line scripting and vectors. It has several built-in functions and libraries that are extensible and allows the users to define their own (customized) functions on how they expect the program to behave while handling the data, which can also be stored in the simple object system.For all intents and purposes, this book serves as both textbook and manual for R statistics particularly in academic research, data analytics, and computer programming targeted to help inform and guide the work of the R users or statisticians. It provides information about different types of statistical data analysis and methods, and the best scenarios for use of each case in R. It gives a hands-on step-by-step practical guide on how to identify and conduct the different parametric and non-parametric procedures. This includes a description of the different conditions or assumptions that are necessary for performing the various statistical methods or tests, and how to understand the results of the methods. The book also covers the different data formats and sources, and how to test for reliability and validity of the available datasets. Different research experiments, case scenarios and examples are explained in this book. It is the first book to provide a comprehensive description and step-by-step practical hands-on guide to carrying out the different types of statistical analysis in R particularly for research purposes with examples. Ranging from how to import and store datasets in R as Objects, how to code and call the methods or functions for manipulating the datasets or objects, factorization, and vectorization, to better reasoning, interpretation, and storage of the results for future use, and graphical visualizations and representations. Thus, congruence of Statistics and Computer programming for Research.

This module series covers how to import, manipulate, format and plot time series data stored in .csv format in R. Originally designed to teach researchers to use NEON plant phenology and air temperature data; has been used in undergraduate classrooms.

The following data shows riding information for members vs casual riders at the company Cyclistic(made up name). This is a dataset used as a case study for the google data analytics certificate.

The Changes Done to the Data in Excel: - Removed all duplicated (none were found) - Added a ride_length column by subtracting ended_at by started_at using the following formula "=C2-B2" and then turned that type into a Time, 37:30:55 - Added a day_of_week column using the following formula "=WEEKDAY(B2,1)" to display the day the ride took place on, 1= sunday through 7=saturday. - There was data that can be seen as ########, that data was left the same with no changes done to it, this data simply represents negative data and should just be looked at as 0.

Processing the Data in RStudio: - Installed required packages such as tidyverse for data import and wrangling, lubridate for date functions and ggplot for visualization. - Step 1: I read the csv files into R to collect the data - Step 2: Made sure the data all contained the same column names because I want to merge them into one - Step 3: Renamed all column names to make sure they align, then merged them into one combined data - Step 4: More data cleaning and analyzing - Step 5: Once my data was cleaned and clearly telling a story, I began to visualize it. The visualizations done can be seen below.

Explanation/Overview: Corresponding dataset for the analyses and results achieved in the CS Track project in the research line on participation analyses, which is also reported in the publication "Does Volunteer Engagement Pay Off? An Analysis of User Participation in Online Citizen Science Projects", a conference paper for the conference CollabTech 2022: Collaboration Technologies and Social Computing and published as part of the Lecture Notes in Computer Science book series (LNCS,volume 13632) here. The usernames have been anonymised. Purpose: The purpose of this dataset is to provide the basis to reproduce the results reported in the associated deliverable, and in the above-mentioned publication. As such, it does not represent raw data, but rather files that already include certain analysis steps (like calculated degrees or other SNA-related measures), ready for analysis, visualisation and interpretation with R. Relatedness: The data of the different projects was derived from the forums of 7 Zooniverse projects based on similar discussion board features. The projects are: 'Galaxy Zoo', 'Gravity Spy', 'Seabirdwatch', 'Snapshot Wisconsin', 'Wildwatch Kenya', 'Galaxy Nurseries', 'Penguin Watch'. Content: In this Zenodo entry, several files can be found. The structure is as follows (files and folders and descriptions). corresponding_calculations.html Quarto-notebook to view in browser corresponding_calculations.qmd Quarto-notebook to view in RStudio assets data annotations annotations.csv List of annotations made per day for each of the analysed projects comments comments.csv Total list of comments with several data fields (i.e., comment id, text, reply_user_id) rolechanges 478_rolechanges.csv List of roles per user to determine number of role changes 1104_rolechanges.csv ... ... totalnetworkdata Edges 478_edges.csv Network data (edge set) for the given projects (without time slices) 1104_edges.csv ... ...
