uncertConvMass {masscor} | R Documentation |
Uncertainty in conventional mass value
Description
The function combines the uncertainty of the conventional mass correction
(as obtained by uncertErrorCorr()
)
and the uncertainty in the balance reading (as obtained by uncertReading()
),
to produce the uncertainty of a conventional mass value.
Usage
uncertConvMass(calibCert, reading, units, sd, sd.units, d, d.units)
Arguments
calibCert |
object of class |
reading |
numeric with balance reading for the mass of the object. |
units |
character with the units of |
sd |
standard deviation when a balance reading is the result of averaging several individual measurements of same object. If not provided the information is taken from the calibration certificate of the balance |
sd.units |
character with the units of standard deviation.
If not provided, the value stated at |
d |
balance division scale. Useful when the balance is operated a a division scale different from that stated in the calibration certificate. This is the common case when the user is give up some readability in order to make faster mass measurements. If not provided. the functions uses the balance division scale stated in the calibration certificate. |
d.units |
character with the units of parameter |
Value
A numeric value of uncertainty for a conventional mass value.
