Apply allometric equations

sol_allometry(data, equation)

Arguments

data

data.frame: input data
equation

character or sol_equation object: either the identifier of the equation to apply, or the equation object itself. Can be a single element (this equation will be applied to all rows of the data) or with length matching the number of rows of the data

Value

the input data frame, augmented with columns "allometric_property", "allometric_value", "allometric_value_lower", and "allometric_value_upper"

Examples

if (FALSE) {
x <- data.frame(LRL=c(11.3,13.9),species=c("Architeuthis dux"),
  stringsAsFactors=FALSE)
## it doesn't matter what the column names are, but we
## need to set the property types correctly
x$LRL <- sol_set_property(x$LRL,"lower rostral length")

## apply a single equation to all rows
sol_allometry(x,c("342218_ML_Roel2000"))

## apply a different equation to each row
sol_allometry(x,c("342218_ML_Roel2000","342218_ML_Clar1986"))
}
