- file
The name of the AURN file to be imported. Default,
file.choose
opens browser. Use of read.table
(in
utils
) also allows this to be a readable text-mode connection or
url (although these options are currently not fully tested).
- header.at
The file row holding header information. This is used to
set names for the resulting imported data frame, but may be subject to
further modifications depending on following argument settings.
- data.at
The first file row holding actual data. When generating the
data frame, the function will ignore all information before this row, and
attempt to include all data from this row onwards.
- na.strings
Strings of any terms that are to be interpreted as NA
values within the file.
- date.name
Header name of column holding date information. Combined
with time information as single date column in the generated data frame.
- date.break
The break character separating days, months and years in
date information. For example, "-" in "01-01-2009".
- time.name
Header name of column holding time information. Combined
with date information as single date column in the generated data frame.
- misc.info
Row numbers of any additional information that may be
required from the original file. Each line retained as a character vector
in the generated data frame comment.
- is.site
Header name of column holding site information. Setting to
NULL turns this option off.
- bad.24
Reset AURN 24 time stamp. AURN time series are logged as
00:00:01 to 24:00:00 as opposed to the more conventional 00:00:00 to
23:59:59. bad.24 = TRUE
resets the time stamp which is not allowed
in some time series classes or functions.
- correct.time
Numerical correction (in seconds) for imported date.
AURN data is logged retrospectively. For 1 hour average data,
correct.time = -3600
resets this to the start of the sampling
period.
- output
Output style. Default "final" using import()
.
- data.order
A vector of names defining the order of data types. AURN
files typically include three data types, actual data and associated data
quality and measurement unit reports. Here, these are defined as "value",
"status" and "unit", respectively.
- simplify.names
A logical (default TRUE) prompting the function to
try to simply data frame names using common chemical shorthand. FALSE
retains names from original file, although these may be modified if they
contain unallowed characters or non-unique names.
- ...
Other parameters. Passed onto and handled by import()
.
