Description

Reads biota.lengd_skalad_v that includes a raising factor and provides weight as a function of length. No raising done. If species only counted at station, not included in algorithm.

Usage

bi_len(con, std = TRUE, trim = TRUE, weights = TRUE)

Arguments

con	oracle connection
std	create standardized/shortcut names (default is TRUE)
trim	trim return only key variables (default is TRUE). Only operational if std is TRUE.
weights	Gets or calculates weights (default is TRUE). Only operational if std is TRUE.
