Introduction to Conditional Statements in R As a programmer, you are likely familiar with conditional statements, which allow your code to execute different blocks of instructions based on certain conditions. In R, one of the most commonly used conditional statements is the if statement. However, in many real-world applications, we need to make decisions that involve some level of uncertainty or randomness. This is where probabilistic programming comes in – a subset of machine learning that involves modeling uncertainty using probability theory.
