Median of Subgroup Ranges Upper Control Limit (UCL)
Description
Calculates the median of subgroup range upper control limit (UCL) used when constructing a xBar_rMedian chart.
Usage
rMedian_UCL(data = data, value = value, grouping = grouping,
formula = NULL, ...)
Arguments
data |
data frame to be processed |
value |
numeric vector in a data frame with values of interest. |
grouping |
single factor/variable to split the data frame "values" by. |
formula |
a formula, such as y ~ x1 + x2, where the y variable is numeric data to be split into groups according to the grouping x factors/variables |
... |
further arguments passed to or from other methods. |
Value
A number; median of subgroup range upper control limit (UCL).
Examples
set.seed(5555)
df <- data.frame(v=rnorm(60, 0, 1), g=rep(c("A","B","C","D","E"), each=12))
