getweight.Rd
Estimate fish weights from potentially sex-specific weight-length relationship parameters returned from getWLpars.
getweight(length, sex, pars, unit.out = c("lb", "kg"), weight, unit.in)
A vector of fish lengths in mm.
A vector of sexes for each entry in length
.
Entries must be one of the following: 'U', 'F', 'M', or 'H'.
A data frame of parameters for the weight-length
relationship as determined from empirical data. The data frame
must have columns of 'A'
and 'B'
, as well as
rows named 'U'
, at a minimum, 'F'
, and 'M'
.
The output from getWLpars
is formatted correctly as is.
The desired units you wish the output to be in. See the
function call for a list of default units available within the function.
For example, "lb"
would return the units of pounds.
A vector of fish weights, where the units for each
measurement are specified in unit.in
.
A vector of units for each measurement in weight
.
Options include KG
, G
, LB
, UNK
. Where, the latter leads to
the assumption that your units are in grams and will be converted
as such.
A vector of measurements in the unit specified using
unit.out
. If weights were provided, then the weights are also
the output. If lengths were provided, then they are converted
to weights. Where, weights are determined from lengths and weight-length
parameters input to the function.
Weights are in the same units used to calculate things, i.e., kg.
