To convert a vector to a data frame in R, you can use the data.frame() method. For example, if you have a vector x <- c(11, 21, 19), you can use the data.frame(vector) function to get the data frame. Syntax data.frame(vectors) Example 1: R program to convert a vector to a data frame Here, we … Read more
To convert a string to a float in R, you can use the as.double() function. For example, as.double(“3.14”) will return 3.14. The as.double() function can also convert an integer to a double-precision vector. Syntax double(length = 0) as.double(x, …) is.double(x) Parameters length: It is a non-negative integer specifying the desired length. Double values will be … Read more
To convert a list to JSON in R, you can use the toJSON() function of the jsonlite package. For example, a list called LIST can be converted to a JSON using the function toJSON(LIST, pretty = TRUE, auto_unbox = True). To install the latest version of the jsonlite package, use the following command. install.packages(“jsonlite”) After … Read more
To convert a list to a numeric value in R, combine the unlist() function and as.numeric() function. The unlist() function in R produces a vector that contains all the atomic components. The as.numeric() function in R is a built-in method that returns a numeric value or converts any value to a numeric value. Expression as.numeric(unlist(data)) … Read more
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
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
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
