This video tutorial introduces basic functions and arguments in the R programming language. The instructor demonstrates how to use functions like round, factorial, and mean for calculations, and explains how to utilize the sample function for generating random values. The core focus is on understanding function arguments and best practices for using them.
round, factorial, mean, and sample.sample() Function: The sample() function's usage is demonstrated, showing how to obtain random samples from a data set using arguments like x (data), size (number of samples), replace (sampling with replacement), and prob (probabilities).args(): The args() function can be used to check the arguments a given function accepts.
