Examples of how to use case_when in R Here we’ll take a look at several examples of how to use the R case_when function. For simplicity and clarity, we’re going to start with a simple example of how to use case_when on an R vector. But since we commonly use case_when withdat...
In R programming, thediff()computes the difference between consecutive elements of the vector, which is passed to the function. The final result is also a vector. For example: x<-c(5,3,4,3,8,9,4,8,1)diff(x)[1]-21-151-54-7 ...
This article demonstrates how to use the source function of base R to run another R script which may be located in the same directory as the first script or in a different directory. It explains how and when to use the chdir argument to change R's workin
Let’s learn how to find the sum of the values with the help of thesum()in R. 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) Vectoris the easiest method tostore multiple elementsin R....
This function returns the last day of the month2months ago, then adds1to calculate the first day of the following month, which is this month’s previous month. In cellC7cell, enter the formula below to return the last day of the previous month: ...
The wrapping function pattern is a good way to apply the don’t repeat yourself pattern (which greatly improves the maintainability of code). We demonstrate a slightly less trivial use of the pattern here. The problems with wrapping/returning functions in R There are at least three problems ...
This article discusses thefread()function in C programming language and the way to use it in the program. fread() Function in C Language Thefread()function requires three arguments: the pointer to an array, the size of each element from the array pointer, and the number of elements to rea...
As a workaround, you need a function which will output a character array instead of a string in R2016b, if you cannot upgrade your MATLAB release. There a several possible solutions, for example: Use theextractBetweenfunction, with a wrapper function which could look like ...
This example demonstrates how to use the RANDBETWEEN function. It has two arguments bottom and top, which determines the range or boundary the RANDBETTWEEN function can output whole numbers from. The image above has the bottom value in cell B4 and it contains 5, the top value in cell C4 ...
For importing data in R from XML files, we need to install the XML package, which can be done as follows: install.packages("XML") To read XML files, we use the in-built function xmlParse(). For example: #To load required xml package to read XML files library("XML") #To ...
