### Description

Learn data visualizations by projects that use real world datasets in the professional industries such as finance, marketing, sales etc.This course will help you master data visualizations techniques and create graphics in R using packages such as ggplot2, lattice package and ggvis package from shiny for adding interactivity into you R graphics.Real world datasets are used for projects. So, not only will you master the graphics in r, you will also be able to interpret your graphics and make an impressive plots. All done by yourself. Why learn data visualization with R?Data Visualization helps people see, interact with, and better understand the data. Whether simple or complex, the right visualization can bring everyone on the same page, regardless of their level of expertise.Almost all the professional industries benefit from making data more understandable. Every STEM field benefits from data analysts that are able to understand data—and so do fields in government, finance, marketing, history, consumer goods, service industries, education, sports, and so on.As the “age of Big Data” and “Artificial Intelligence (AI)” kicks into high gear, visualization is an increasingly key tool to make sense of the trillions of rows of data generated every day. Data visualization helps to tell stories by curating data into a form easier to understand, highlighting the trends and outliers. A good visualization tells a story, removing the noise from data and highlighting useful information. With R tools such as ggplot2 , lattice package, we can create visually appealing graphics and data visualizations by writing few lines of code. For this purpose R is widely used and it is easy to use and understand when it comes to data visualizations, good appealing graphics, data analysis (dplyr) etc. Through R, we can easily customize our data visualization by changing axes, fonts, legends, annotations, and labels.In this data visualization course you will learn the following:R for beginners: Vectors, Matrices, Arrays, Data frames and ListsFactors in R: Create factors, understand factor levelsregular expressions in r: grep and gsub functionsreshape package for data analysis: melt and casting functionstidyr package for data analysis: gather and spread functionsdplyr package for data analysis: merge functions, filter, select, sort, arrange, pipe operator etcAfter Mastering R Programming for beginners and Data Analysis, you will begin creating graphics with r and visualizations.
