## Overview

We create this package, `mvMonitoring`

, from the foundation laid by Kazor et al (2016). This package is designed to make simulation of multi-state multivariate process monitoring statistics easy and straightforward, as well as streamlining the online process monitoring component.

## Installation from CRAN

Install the stable version of this package via

`install.packages("mvMonitoring")`

## Installation of Development Version

Make sure you have the latest version of the `devtools`

package, and pull the package from GitHub.

`devtools::install_github("gabrielodom/mvMonitoring")`

Load the library after installation by

`library(mvMonitoring)`

## Examples

These are the examples shown in the help files for the mspProcessData(), mspTrain(), mspMonitor(), and mspWarning() functions.

```
# Generate one week's worth of normal operating (NOC) data recorded at the one-
# minute level
nrml <- mspProcessData(faults = "NOC")
# The state values are recorded in the first column.
n <- nrow(nrml)
# Calculate the training summary, but save five observations for monitoring.
# This function will treat the first 3 days as in control (IC), and then update
# the training window each day.
trainResults_ls <- mspTrain(
data = nrml[1:(n - 5), -1],
labelVector = nrml[1:(n - 5), 1],
trainObs = 4320
)
# While training, we included 1 lag (the default), so we will also lag the
# observations we will test.
testObs <- nrml[(n - 6):n, -1]
testObs <- xts:::lag.xts(testObs, 0:1)
testObs <- testObs[-1,]
testObs <- cbind(nrml[(n - 5):n, 1], testObs)
# Run the monitoring function.
dataAndFlags <- mspMonitor(
observations = testObs[, -1],
labelVector = testObs[, 1],
trainingSummary = trainResults_ls$TrainingSpecs
)
# Alarm check the last row of the matrix returned by the mspMonitor function
mspWarning(dataAndFlags)
```

The `R`

code to build and save the simulation graphics from the paper are in the `inst/mspGraphsGrid.R`

file.
