Create a formula for RNA degradation

Implements a non-standard evaluation version.

degrade_(x, d, t)

Arguments

x	initial concentration.
d	a degradation rate.
t	a longitude of the modelled period.

Value

an expression for the calculation of the RNA level after degradation during time t.

Examples

x <- amount("a")
degrade_(x,b,c)
#> a * exp(-b * c)
# a * exp(-b * c)
