Examples

# create an uncertainty budget
cor.mat <- matrix(c(1, -0.7, -0.7, 1), 2, 2)

u.budget <- uncertaintyBudget(x = list(name = c("x0", "x1"), 
	mean = c(10, 20), u = c(1, 5), unit = c("kg", "kg"), dof = c(10, 10),
	label = c("x[0]", "x[1]"), distribution = c("normal", "normal"),
	description = c("measurand mass", "sample mass"),
	type = c("A", "A")), 
	y = cor.mat)
u.budget

# estimate the measurand uncertainty using an uncertainty budget,
# a measurand definition and a selected estimating method.
GFO.res <- uncertainty(x = u.budget, 
y = list(measurand_name = "ratio.GFO",
         measurand_label = "ratio[GFO]", 
         measurand_model = "x0/x1",
	   measurand_description = "ratio of masses at 20 degrees celsius",
         method = "GFO", alpha = 0.05))

GFO.res

# create an uncertainty summary object
GFO.sum <- summary(GFO.res)

# implicit call to the print method
GFO.sum

# same as
print(GFO.sum)

# uncertainty summary structure
attributes(GFO.sum)
