Description

Work with quantity units.

Usage

get_qty_units(q)

get_qty_units_with_label(q, label = names(q))

Arguments

q	quantities
label	text label to use with the units - single value or vector of the same length as q. By default uses the names of q, which only works if q is a list or data frame.

Functions

• get_qty_units(): get units from a quantity, list of quantities or data frame (returns NA for objects/columns that are not quantities)

# quantity units examples
qty(5000, "g") %>% get_qty_units()
x <- list(a = qty(5000, "g"), b = 42, c = qty(100, "mbar"))
x %>% get_qty_units()
# labels with units
get_qty_units_with_label(qty(0.1, "mM"), "concentration")

# make labels with units for data frame columns
x <- data.frame(a = qty(1, "mg"), b = 2, c = qty(100, "mbar"))
get_qty_units_with_label(x)
get_qty_units_with_label(x, "same label")
