This function is particularly useful when working with matrices, arrays, and data frames. Below, we will discuss how to use dim() to both retrieve and set dimensions, with examples for better understanding.Syntax: dim(x)Param 2 min read Get the First parts of a Data Set in R Programming - head() Function head() function in R Language is used to get the first parts of a vector, matrix, table, data frame or function.
