To convert a list to an array in R, you can use the combination of the array() function with unlist() function. The syntax is array(unlist(main_list)), where main_list is the list that needs to be converted into an array. The array() function takes the following arguments: data: The input data must be a vector, matrix, or array. … Read more
To convert List to Matrix in R, use the matrix() function and pass the unlist(list) as an argument. The unlist() method returns a vector that contains all the atomic components which occur in list data, and the matrix() function will convert the vector into a matrix. To convert the list into a m x n … Read more
To convert a list to a data frame in R, use the as.data.frame() function. For example, df = as.data.frame(list), where the list is the input and df is the output data frame. The as.data.frame() function checks if an object is a data frame and if not, it will try to coerce it if possible. It takes a … Read more
To convert a list to vector in R, you can use the unlist() function. The unlist() function takes a list as one of the arguments and returns a vector by preserving all atomic elements. Syntax unlist(x, recursive = TRUE, use.names = TRUE) Parameters list The unlist() function takes a list as a required parameter, which … Read more
Add a column to dataframe in R There are the following methods to add a column to an R data frame. Method 1: Using the $ operator Method 2: Using the square ([ ]) brackets Method 3: Using the cbind() function Method 1: Adding a column using the $ operator To add a new column in the … Read more
To add vectors in R, use the + operator. If the vectors are of different lengths, then the shorter one is repeated until its length is equal to that of the longer one. Example 1: How to add vectors in R fv <- 1:4 cat(“The first vector is: “, fv, “\n”) sv <- 5:8 cat(“The second … Read more
The ceiling() is a built-in R function that rounds up to the nearest integer. For example, ceiling(3.14) returns 4. Syntax ceiling(x) Parameters The ceiling() function accepts one parameter whose value needs to be rounded off. If the x parameter is a positive or negative numeric value, the ceiling function returns the ceiling value. If it … Read more
Use the sqrt() function to calculate the square root of a numeric value or a vector in R. For example, sqrt(16) returns 4, and sqrt(c(1, 4, 9)) returns c(1, 2, 3). Syntax sqrt(n) Parameters The sqrt() function accepts only one parameter, which takes n as a number. Return value It returns the square root of the … Read more
The origin of data frames begins from intensive experimental research in the world of statistical software. The tabular data is referred to by the data frames. R Data Frame Data Frame in R is a table or two-dimensional array-like structure in which a row contains a set of values, and each column holds values of … Read more
Functions in R are used to logically break our code into smaller pieces, which become easy to maintain and understand. A function is an object that contains multiple statements that are run together every time the function is called. For example, in R programming language, a function is an object, so the R interpreter can … Read more
