read_sbe_cnv: Read Seabird .cnv files

In paleolimbot/sbe: Process and Convert Files Created by 'Seabird' Products

Description

The .cnv file format is the primary file format used for input and output to SBE Data Processing. The format is essentially a fixed-width format using 11 characters for each column.

Usage

read_sbe_cnv(
  file,
  skip = 0,
  n_max = Inf,
  header = read_sbe_header(file),
  col_names = read_sbe_cnv_colmeta(file, header)$name,
  widths = rep(11L, length(col_names))
)

read_sbe_cnv_colmeta(file, header = read_sbe_header(file))

read_sbe_header(file, n_header = 500)

Arguments

file	A file, URL, or connection. Files ending in .gz, .bz2, .xz, or .zip will be automatically uncompressed; URLs will be automatically downloaded. See readr::read_lines() for a full description of how this parameter is interpreted.
skip	Number of non-header rows to skip.
n_max	Maximum number of rows to read.
header	A previously read value obtained from read_sbe_header().
col_names	The column names. Defaults to the name column of read_sbe_cnv_colmeta().
widths	A vector the same length as col_names denoting the widths of each field in characters. Defaults to 11.
n_header	The starting guess for number of header lines.

Examples

file <- system.file("extdata/faroe/faroe.cnv", package = "sbe")
read_sbe_cnv(file)
read_sbe_cnv_colmeta(file)
head(read_sbe_header(file))

# header information is kept on read with the 'header' attribute
cnv <- read_sbe_cnv(file)
head(attr(cnv, "header"))
