Writes a comma-separated file containing the data frame stored in
the data slot of the first argument. The file is suitable
for reading with a spreadsheet, or
with read.csv(). This output file will contain
some of the metadata in x, if metadata is TRUE.
write.ctd(object, file, metadata = TRUE, flags = TRUE, format = "csv")a ctd object.
Either a character string (the file name) or a connection. If not
provided, file defaults to stdout().
a logical value indicating whether to put some selected metadata elements at the start of the output file.
a logical value indicating whether to show data-quality flags as well as data.
string indicating the format to use. This may be "csv"
for a simple CSV format, or "whp" for the World Hydrographic
Program format, described in reference 1 and exemplified in reference 2.
