Open the R environment via desktop icons or terminal, script in RStudio, run lines with ctrl+enter, and define X <- 1:5 and Y <- c(6,7,8,9,10).
Learn to create bar charts for categorical variables in R by building frequency tables from raw data, plotting with barplot, and customizing orientation and colors for clear visualization.
Create box plots for quantitative variables in R to inspect distributions, medians, and potential outliers. Use built-in functions with minimal preprocessing to customize labels and colors for clearer comparisons.
Explore descriptive statistics for quantitative variables using both built‑in functions and a specialized package, applied to the social_network_gutsiest dataset. Compute the five‑number summary (min, first quartile, median, third quartile, max), along with the mean and handling of missing values, and learn how to summarize all variables at once for quick data insight.
Explore how to create new variables by combining normal-distribution vectors into composites in R, using addition and multiplication to shape data for analysis.
Explain how to examine association between two quantitative variables by creating a scatterplot with the Google Correlate data, add a regression line and smoothing line, and interpret a positive trend.
Read, access, and summarize data in R for data science, using real exercises from the course to reinforce practical data handling.
Master quick installation of the R language on Ubuntu Linux and dive into data science with real exercises.
Learn R programming and unlock the power of statistical computing for data science, analytics, and visualization. This course introduces the R language, a popular open-source programming environment designed for statistical computing and graphics. Whether you are a beginner or an experienced data analyst, this course will help you gain practical skills to analyze, visualize, and present data effectively.
You’ll start by learning how to install R and RStudio on your computer and import data from SPSS, spreadsheets, and other sources. The course covers essential R commands and packages, enabling you to compute descriptive statistics, create new variables, and check the reliability of your data. You’ll also learn how to identify data outliers, test statistical assumptions, and perform key analyses, such as comparing means.
Hands-on examples guide you through data visualization, including bar charts for categorical variables, histograms, scatter plots, and more. You’ll also learn how to extract charts and tables from R and share results in presentations or web pages. For Linux users, the course includes guidance for quickly installing R on Ubuntu Linux.
By the end of this course, you’ll have the confidence to use R programming for real-world data analysis, create compelling visualizations, and make data-driven decisions. This course is ideal for data analysts, statisticians, students, and anyone interested in data science looking to leverage R’s powerful statistical and graphical capabilities.
