Syntax: mode(x) mode(x) <- value Here "value" is the desired mode or ‘storage mode’ (type) of the object Parameters: x: R object Example 1: Python3 # R program to illustrate # mode function # Init 1 min read Convert type of data object in R Programming - type.convert() Function type.convert() function in R Language is used to compute the data type of a particular data object. It can convert data object to logical, integer, numeric, or factor. Syntax: type.convert(x) Parameter: x: It can be a vector matrix or an array Example 1: Apply type.convert to vector of numbers Pytho 2 min read Display the internal Structure of an Object in R Programming - str() Function str() function in R Language is used for compactly displaying the internal structure of a R object. It can display even the internal structure of large lists which are nested. It provides one liner output for the basic R objects letting the user know about the object and its constituents. It can be 3 min read Convert an Object to List in R Programming - as.list() Function as.list() function in R Programming Language is used to convert an object to a list. These objects can be Vectors, Matrices, Factors, and dataframes. Syntax: as.list(object) Parameters: object: Vector, Matrix, factor, or data frame R - as.list() Function ExampleExample 1: Converting Vector to list 2 min read Check if Object is of the Character Data type in R Programming - is.character() Function is.character() Function in R Language is used to check if the object is of the form of a string/character or not. It will return true if any element of the object is of the character data type. Syntax: is.character(Object) Parameter: Object: It could be an array, list, vector, etc. Example 1: Python 1 min read Like
