Hi Gents,

I need to get the control limits from qcc function.

As follows:

qcc(MDI, type = "xbar.one")

Call:

qcc(data = MDI, type = "xbar.one")

xbar.one chart for MDI
Summary of group statistics:

Min. 1st Qu. Median Mean 3rd Qu. Max. 0.3266 0.4249 0.4371 0.4333 0.4451 0.4858
Group sample size:  1

Number of groups:  383

Center of group statistics:  0.4332557

Standard deviation: 0.01520659
Control limits:

      LCL       UCL

 0.387636 0.4788755

I want to get LCL and UCL. It is possible ?

Thanks in advance,

Renata


Hello,

try this:

results <- qcc(data = MDI, type = "xbar.one")

names( results )

results$limits

results$limits[1]
results$limits[2]
