estimate() function returns LengthType NA

[LauraMannocci]

Hello,

We are using the estimate() function of rfishbase (version 4.0.0) with a vector of our species names as the argument.

 sp = c( "Abalistes stellatus", "Ablennes hians", "Acanthocybium solandri")
a_b <- rfishbase::estimate(sp)

a_b is a table with the following 71 columns,k including Species, a, b etc

However the LengthType column contains only NA. As a result we don’t know if a and b parameters should be applied with length type = FL or length type = TL.

Is it normal that the LengthType column is NA ?

Many thanks

To complement my previous post: when applying the formula weight = a * length^b , how do I know if a and b should be applied to LengthType = FL or LengthType = TL ?

Hi Laura The length type of the sample should be available in the data record. If it isn’t the. It is assumed as TL. Thanks Deng
