  drop = TRUE,
  echo = FALSE,
  ...
)

read.scslen(x, file, survey, species, ...)

Arguments

...	Other parameters passed onto locate functions or used to subset data.
species	Species code or name.
drop	Logical value specifying whether to remove empty data rows.
echo	Logical value specifying whether to report information as data is being read.
year	Survey year(s).

Examples

 
# Read snow crab survey set data files:
x <- read.scsset(year = 2019)      # Read single year.
x <- read.scsset(year = 2010:2015) # Read range of years.

# Read specific tow data:
x <- read.scsset(2020, valid = 1)  # Load only valid tows.
x <- read.scsset(2020, tow.id = "GP354F")
x <- read.scsset(2020, date = "2020-07-13")
x <- read.scsset(2020, zone = "F")

# Using snow crab set data to specify corresponding biological data:
b <- read.scsbio(read.scsset(2020, valid = 1, zone = "F"))
b <- read.scsbio(2020, category = "MI")
