In this tutorial, we will try to find the sum of the elements of the vector. The syntax of the sum() function is = sum(x,na.rm=FALSE/TRUE) [Vector](/community/tutorials/vectors-in-r) is the easiest method to store multiple elements in […]

In this tutorial let's see how we can use paste() to concatenate the strings and values. paste(): Takes multiple elements from the multiple vectors and concatenates them into a single element. Along with paste() function, R has another function named paste0(). Yes, […]
