Sorting is a common operation in Programming is when data is arranged into meaningful order that makes it simpler to understand and analyze. In R, you can store data in various data types such as vectors, data frames, matrices, and arrays. sort in r The sort() is a built-in R function used to sort or … Read more
R has no built-in string data type. Instead, it has a character, and you can use the is.character() function to check. Type conversions in R work as you would expect. For example, adding the character string to a numeric vector converts all the vector items to the character. r toString The toString() is a built-in … Read more
