tacmagic (version 0.3.1)

change_units: Convert radioactivity units

Description

Change the radioactivity units of a tac or numeric object to the specified desired units (e.g. Bq, kBq, MBq, nCi, uCi, mCi, Ci). For convenience, if the unit is per volume ("x/cc" or "x/mL"), the "/cc" part is ignored for the conversion.

Usage

change_units(x, to_unit, from_unit)

Arguments

x

time-activity curve or numeric object

to_unit

the desired unit (e.g. "kBq")

from_unit

not used for tac object (it is in the tac object), but for numeric objects, must be specified (e.g. "nCi")

Value

the converted object, same type as x

Examples

# NOT RUN {
f <- system.file("extdata", "AD06.tac", package="tacmagic")
AD06_tac <- load_tac(f, format="PMOD")
AD06_tac_nCicc <- change_units(AD06_tac, to_unit = "nCi/cc")

change_units(5, to_unit = "kBq", from_unit = "nCi")
change_units(0.185, to_unit = "nCi", from_unit = "kBq")
# }
