uBar_LCL {ggQC} | R Documentation |
Calculates point-wise lower control limit (LCL) for count data acquired over a variable area of opportunity.
uBar_LCL(y, n, na.rm = FALSE, ...)
y |
Vector of counts per unit opportunity (rate). Observations may have a different area of opportunity, n. |
n |
A vector representing the area of opportunity. |
na.rm |
a logical value indicating whether NA values should be stripped before the computation proceeds. |
... |
further arguments passed to or from other methods. |
A vector; point-wise 3-sigma lower control limit (LCL)
