The Basics of R Programming

Learn this skill in these courses:

• Self-Paced eLearning: R Programming eLearning course.

R Programming is a powerful and versatile open-source language used for statistical analysis, data processing, and graphical representation. It is a programming language that can be used to perform data analysis, create models, conduct simulations, and visualize results. This makes it an ideal language for scientific computing and is widely used by researchers in different disciplines such as ecology, economics, and public health.

In R Programming, several elements help define the language - operators, arithmetic/relational/logical operators, assignment operators, conditional statements (ifelse(), switch function), loops (break statement and next statement) as well as functions.

The operators in R are important components of the language and control the execution of statements. Arithmetic operators are used to perform basic math operations such as addition, subtraction, multiplication, division, etc. Relational operators compare two values and return a logical result depending on the relationship between them. Logical operators combine the results from relational expressions and allow for more complex evaluations. Assignment operators assign values to variables and can also be used to perform operations on values, such as incrementing or decrementing them.

Conditional statements in R are used to control the flow of a program by evaluating conditions and deciding which statement block should be executed based on the result of the evaluation. The ifelse() function is a special construct used to execute one or the other block of code based on the evaluation of an expression. This expression must be enclosed in parentheses and followed by two statement blocks, one for when the condition evaluates to TRUE and another for when it evaluates to FALSE.

Loops are also important tools in R programming. They allow repeated execution of a block of code until certain conditions are met. The break and next statements allow for more control over the flow by allowing early termination or skipping of the loop. The scan() function allows execution of a file containing R code, while running an R script requires executing commands from within the same window. Finally, batch scripts can be used to execute multiple R scripts at once.

R functions are an essential part of the language and allow for easier reuse of code by abstracting it into a single callable procedure. They can also be used to pass values from one function to another, allowing for flexibility when designing programs.

Statistics is the discipline of collecting, analyzing, interpreting, and presenting data. It allows us to make informed decisions based on empirical evidence rather than assumptions or guesswork. It is an essential part of research in many fields such as medicine, economics, engineering, and government.

Data can be divided into two types: qualitative and quantitative. Qualitative data is information that has no numerical value and can include things such as gender, race, or opinions. Quantitative data is information that can be measured numerically such as height, weight, or test scores.

Once the type of data is determined, it must be organized into an order of measurements to accurately analyze it. The four common types of measurements for organizing data are nominal, ordinal, interval, and ratio. Nominal measurements describe categories or labels that do not have any numerical value associated with them such as gender or type of job. Ordinal measurements, on the other hand, organize categories by rank order such as in a survey ranking the best countries to live in. Interval measurements provide greater detail by providing a numerical value but do not have an absolute zero point such as temperature. Lastly, ratio measurements establish an absolute zero point allowing for comparisons between two or more values like mileage ratings or income levels.

Statistical investigations involve gathering data and then analyzing it to conclude. The steps typically followed are: define the problem, collect and organize data, summarize the data in a useful form, analyze the data to determine patterns or relationships and draw conclusions based on those results.

One of the most common types of statistical analysis is normal distribution which describes how often certain events occur within a population. This can be used to understand things like customer buying habits or employee performance. The normal distribution can also be used to calculate the probability of an event occurring.

To measure the distance between two variables, a variety of distance measures are available for use in data analysis. Euclidean Distance is one of the most commonly used and measures the straight-line distance between two points on a graph. Manhattan Distance measures the distance between two points based on the number of steps needed to move from one point to the other. Minkowski Distance is a more generalized version of both. Mahalanobis Distance is more flexible since it can take into account different scales, and Cosine Similarity is used in natural language processing to quantify the similarity between two documents.

To understand the relationship between two variables, correlation can be used to determine if there is a linear relationship between them. Pearson Product Moment Correlation (PPMC) is one of the most commonly used correlations and measures the strength of a linear relationship using an R-value that ranges from -1 to +1. The Dist() function in R can be used to calculate the distance between two points. The Distance Matrix Computations function can also be used to quickly calculate the distance between multiple points.
