convert_units: A safe version of 'measurements::conv_unit()'.

In forestgeo/fgeo.biomass: Calculate Biomass with the Best Available Allometries

Description

Unlike measurements::conv_unit() this function doesn't fail if it can't convert a unit – instead it outputs NA.

Usage

convert_units(x, from, to, quietly = FALSE)

Arguments

x	a numeric vector giving the measurement value in its original units.
from	the unit in which the measurement was made.
to	the unit to which the measurement is to be converted.
quietly	TRUE suppresses warning.

Value

As in measurements::conv_unit() if possible, or NA.

Examples

convert_units(c(1, NA), from = "cm", to = "m")
# Same
measurements::conv_unit(c(1, NA), from = "cm", to = "m")

# Passes
convert_units(c(1, 10), from = "cm", to = c("m", "bad"))
convert_units(c(1, 10), from = "cm", to = c("m", "bad"), quietly = TRUE)
# Errs
try(measurements::conv_unit(c(1, 10), from = "cm", to = c("m", "bad")))
