The apply() function is bundled with the R package. The apply() function can be feed with many functions to perform repetitive operations on a collection of objects (data frame, list, vector, etc.). The apply() functions form the basis of more complex combinations and helps to perform operations with very few lines of code. More specifically, … Read more
The mode in R is the value that has the highest number of occurrences in a set of data. Unlike the mean and median, the mode can have both numeric and character data. Mode in R To calculate mode in R, you have to define the user-defined function. In R, mean() and median() are standard … Read more
Statistical functions take the R vector as an input besides the arguments and give the result. R has many inbuilt statistical functions, and mean() is one of them. The mean of an observation variable is a numerical measure of the prime location of the data values. Mean is the sum of its data values divided by data count. … Read more
To calculate the sum of vectors in R, use the sum() function. The sum() method returns the sum of all the elements present in its arguments. If it is a vector, then it will return the sum of all vector elements. Sum in R The sum() function in R calculates the sum of a numeric … Read more
If statement can be followed by the optional else statement, which executes when the boolean expression is FALSE. If the boolean expression evaluates TRUE, then the if block will be executed; otherwise, the else block will be executed. You can make a decision in R programming using the conditional If…Else statement. If-else statements are control structures in any programming … Read more
R list is a data structure having elements of different data types. To create a list in R, use the list() function. To access the list, use the indexing. You can use integer, logical, or character vectors for indexing. List in R can be modified that means you can add, update, or delete the list … Read more
Array in R is a list or vector with two or more dimensions. An array is like a stacked matrix, and a matrix is a two-dimensional array. R Array R arrays are objects which can store data in more than two dimensions. Uni-dimensional arrays are called Vectors. A two-dimensional array is called Matrix. More than … Read more
Factors are the list of unique values that are stored as integers. Factors are beneficial in data analysis for statistical modeling. Factors are data structures used for fields that take only predefined, a finite number of values (categorical data). R Factor Factors in R are the data objects used to categorize the data and store … Read more
If you are working in R language, you should probably know that datasets are often stored as zip or tar files, and so R provides two commands to deal with zip files and R files. How to zip files in R To zip files in R, use the zip() function. The zipped file is stored inside the current … Read more
List in R is a data structure having elements of different data types. A Vector contains all elements of the same type is called an atomic vector, and a vector containing all elements of a different type is called List in R. R List A list is a particular type of vector but can store mixed … Read more
