as.lisst: Coerce data into a lisst object

Description

Coerce data into a lisst object

Usage

as.lisst(data, filename="", year=0, tz="UTC", latitude=NA, longitude=NA)

Arguments

data

A table (or matrix) containing 42 columns, as in a LISST data file.

filename

Name of file containing the data.

year

Year in which the first observation was made. This is necessary because LISST timestamps do not indicate the year of observation. The default value is odd enough to remind users to include this argument.

tz

Timezone of observations. This is necessary because LISST timestamps do not indicate the timezone.

latitude

Latitude of observation.

longitude

Longitude of observation.

Value

• An object of class "lisst" (for details, see read.lisst).

Details

If data contains fewer than 42 columns, an error is reported. If it contains more than 42 columns, only the first 42 are used. This is used by read.lisst, the documentation on which explains the meanings of the columns.

References

The LIST-100 users guide (version 4.65), which provided the information for this function, was downloaded in late May 2012, from http://www.sequoiasci.com/products/fam_LISST_100.aspx.
