Now we will plot an x-bar chart where n > 1. Īs you can see, qcc generated a chart as well as provided information about the chart including the control limits, mean and standard deviation, the number of Shewhart rule violations for both runs and limits, and it color codes the violations.Ĭreate a x-bar chart for n >1 and customize the chart # $ call : language qcc(data = chartdata, type = "xbar.one", plot = TRUE) Type = "xbar.one", # The chart type (in this case it lets qcc know that n = 1) Simply call the data set, the type of chart to generate, and whether to display a plot of the chart as shown below. Once we’ve called the qcc library, we can use qcc to make an x-bar chart of the data as follows. (To install it in RStudio go to the “Tools” menu, select “Install Packages…” and type “qcc” into the packages field being sure to also select “Install Dependencies” and click “Install.” if you are not using RStudio, you can type “install.packages(”qcc“)” into the R console.) library(qcc) ![]() First we’ll need to call the qcc package, and if this is the first time we’ve used it we’ll need to install it. Making a plot from the data is quite simple.
