Method 1: Using the print() function An efficient and easiest way to print a string in R is to use the “print()” function. The print() is a built-in function that takes … Read more
Here are three ways to append multiple elements to a Vector in R. Using the “c()” function Using the “append()” function Using <<- operator Method 1: Using the c() function The c() is a built-in function that combines multiple elements into a single vector in R. rv <- c(11, 21, 46) fv <- c(rv, 18, … Read more
To convert a list to a numeric value in R, you can “combine the unlist() function and the as.numeric() function.” The “unlist()” function produces a vector that contains all the atomic components. The as.numeric() function returns a numeric value or converts any value to a numeric value. Syntax as.numeric(unlist(data)) Parameters data: It is the data is … Read more
Here are seven ways to convert a list to a data frame in R. Using as.data.frame() function Using List to a DataFrame using t() Convert Nested List to a DataFrame Convert Nested List to a DataFrame by Rows Use data.table Using tibble package Using dplyr package Method 1: Using the as.data.frame() function The as.data.frame() function checks if an … Read more
Lists are the R objects which contain elements of different types like − numbers, strings, vectors, and other lists inside them. How to Create a List in R To create a list in R, use the “list()” function. To check the type in R, use the “typeof()” method. To check the length of the List, … Read more
R vector is simply a list of items of the same type. To combine the list of elements to a vector in R, you can use the “c()” function and separate the items by a comma. How to Create a Vector in R? To create a Vector in R, we generally use the “c()” function, … Read more
R is a programming language for statistical computing and graphics1. Data miners, bioinformaticians, and statisticians often use it for data analysis and visualization. It is designed as a statistical platform for data cleaning, analysis, manipulation, and representation. R language allows integration with the procedures written in the C, C++, Python, .Net, or FORTRAN languages for … Read more
To check if the number is positive, negative, or zero in R, you can use the “comparison operators”. If the value is greater than 0, it is positive; if it is less than 0, then negative; and if it is equal to zero(0), it is 0. data <- as.double(readline(prompt = “Enter a number: “)) if … Read more
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 one variable”. In Data Frame, each element forms the column, and the contents of the component form the rows. In short, a data frame is a data structure that … Read more
