Visually validate the check standard

Visually inspect plots of the tea check standard absorbance compared to the long-term standard.

Usage

validate_std(abslist, qaqc_dir = NULL, tolerance = 0.2)

Arguments

abslist

An abslist object.

qaqc_dir

File path to the QAQC files generated with create_mdl() and create_std(). Default is a user-specific data directory rappdirs::user_data_dir().

tolerance

Maximum percent deviation that the check standard can vary from the long-term values without being flagged.

Value

A ggplot object showing the absorbance of the check standards, the long-term standard (dashed line), and the tolerance thresholds (gray ribbon).
