Returns the calibration data stored in the current session. If no
calibration has been run yet, the function attempts to load a
previously persisted calibration from the user cache directory.
Returns NULL when no calibration is available.
Value
A list as returned by amatrix_calibrate, or
NULL if no calibration data exists for this session.
Examples
cal <- amatrix_calibration_info()
is.null(cal) # TRUE when no calibration has been run
#> [1] TRUE
