get_survey: get_survey

In Maritimes/Mar.datawrangling: A suite of tools for extracting, filtering and aggregating data from the Maritimes fisheries science databases

get_survey

Description

This function facilitates the extraction of particular survey from the rv database. Within the groundfish data are a number of survey all mixed together. They are typically differentiated via specific selections of 1) type; 2) date (i.e. month and year), and 3) strata. Since this can be confusing, this function was written to help ensure that the extracted sets match the survey they should.

Usage

get_survey(
  db = NULL,
  survey = NULL,
  keepBadSets = FALSE,
  data.dir = NULL,
  quiet = TRUE,
  env = .GlobalEnv
)
