Arrays and multidimensional data structures; factors and categorical data handling; data frames creation and operations; accessing and modifying data frames; data sorting, merging, sub-setting; data aggregation; data cleaning basics; preparing datasets for business analytics applications.

Decision-making structures (if, if-else, nested conditions, switch); loops (for, while, repeat); loop control (break, next); introduction to functions; built-in functions (statistical, mathematical, date-time); user-defined functions; recursion basics; application of functions in business analytics tasks.

Data visualisation using R: bar charts, histograms, line graphs, pie charts; grouped and stacked charts; interpretation of visual outputs; business data storytelling; introduction to exploratory data analysis (EDA); dashboards overview; business applications of R in marketing, finance, HR, and operations analytics. Practical Activities 1. Data cleaning and manipulation using real-world business datasets in R. 2. Creation of vectors, matrices, data frames and performing basic operations. 3. Writing R functions to solve simple business analytics problems. 4. Generating charts (bar, histogram, line, pie) and interpreting business insights. 5. Case-based EDA of sales/HR/financial dataset using R.
