I'm trying to normalize the data. My code is this: library(timeDate) library(timeSeries) data("AirPassengers") AP <- as.matrix(AirPassengers) P <- matrix(AP, nrow = 12,byrow = TRUE) ran <- sample(1:12, 0.9 * 12) nor <-function(x) { (x -min(x))/(max(x)-min(x)) }...

I’ve set up some sample data with Boston winter snowfall data. You could head to https://bit.ly/BostonSnowfallCSV and right-click to save the file as BostonWinterSnowfalls.csv in your current R project working directory. But one of the points of scripting is to replace manual work—tedi...
xi: The ith value in the dataset xbar: The sample mean s: The sample standard deviation The examples below demonstrate how to scale one or more variables in a data frame using the z-score standardization in R by using the scale() function and the dplyr package. Standardize just one variab...
To create the class instance from the document, you call one of the Open() methods. Several are provided, each with a different signature. The sample code in this topic uses the Open(String, Boolean) method with a signature that requires two parameters. The first parameter takes a full ...

Using cbind() to merge two R data frames We will start with thecbind() R function. This a simpleway to joinmultiple datasets in R where the rows are in the same order and the number of records are the same. This means we don’t have any remaining columns out of place after merging...
to perform tasks such as creating new processes and communicating with other processes. Many of the tools that you see in this chapter are often thought of as performance-monitoring tools. They’re particularly helpful if your system is slowing to a crawl and you’re trying to figure out why...
In all cases, the basic approach for data transforms is the same. The heart of the RevoScaleR data step is a list oftransforms, each of which specifies an R expression to be evaluated. The data step typically is an assignment that either creates a new variable or modifies an existing varia...
