recalculate {gasanalyzer}

Recalculate gas-exchange data based on a set of equations.

Description

The recalculation uses equations in a list of quosures provided as argument. This list can be obtained from create_equations() or read_6800_equations().

Usage

recalculate(df, eqs = NULL)

Arguments

df

A data frame or an extension thereof (e.g. a tibble).

eqs

a list of quosures that define how the df will be altered.

Value

A tibble with recalculated columns as specified by the eqs argument

Examples

exampledir <- system.file("extdata", package = "gasanalyzer")
# import factory calibration for example data:
import_factory_cals(exampledir)

# read data:
li6800 <- read_6800_xlsx(paste0(exampledir, "//lowo2.xlsx"))

# recalculate using xlsx equations:
li6800 <- recalculate(li6800)

# recalculate using gasanalyzer default equations for the li6800:
li6800_ge <- recalculate(li6800, create_equations(c("default", "li6800")))

# the difference is that units have been enforced using gasanalyzer, which
# has been recorded in a column:
all.equal(li6800, li6800_ge[names(li6800)], tol = 0.01)
