Many times, we need an empty matrix and want to fill it later as per our requirement. Below are a few examples to achieve the same.In this article, we will be looking into creating an empty matrix in R and in the final section we will see how to verify if an object is a …
A matrix, as we all know, is a rectangular array arranged in rows and columns. In terms of programming language, matrix is a collection of data-elements arranged in a two-dimensional rectangular form. In this article, we will know all about creating matrices in R, and we will be using different methods here to help you …
Vector of zeros is sometimes required to initialize a vector with values or neutralize it after performing a few operations. In this article, we will be creating a vector of zeros using different ways. using integer() function using numeric() function using rep() function R : Create a vector of zeros using integer () function The …
Often, we have a requirement to find out the index of the first occurrence of an element in the vector so that some operations can be performed on the same. There are many ways to do the same in R; we will go through a few of them.
Empty vectors in R are the vectors of length zero. We often need to create empty vectors in a program so that elements can be added later as and when required. While there are several ways to do the same, we will be talking about few of them.
Vectors are fundamental data structures in R with logical, integer, double, character, and raw data types. Vectors are somewhat similar to what is arrays in C. In this article, we will be learning how to create vectors in R using some primary ways: using c() function. using ‘:’ using rep() function using vector() function using …
In this article, we will be setting up a working directory in R using different techniques and will also verify if that has been set correctly.
