\title{Coerce Data Into a met Object}
\usage{
as.met(time, temperature, pressure, u, v, filename = "(constructed from data)")
}
\arguments{
\item{time}{Either a vector of observation times (or character strings that can be
coerced into times) or the output from \code{canadaHCD::hcd_hourly} (see reference 1).}

\item{temperature}{vector of temperatures.}

\item{pressure}{vector of pressures.}

\item{u}{vector of eastward wind speed in m/s.}

\item{v}{vector of northward wind speed in m/s.}

\item{filename}{optional string indicating data source}
}
\value{
A \linkS4class{met} object.
}
\description{
Coerces a dataset into a met dataset. This fills in only a few of the typical
data fields, so the returned object is much
sparser than the output from \code{\link[=read.met]{read.met()}}. Also, almost no
metadata fields are filled in, so the resultant object does not store
station location, units of the data, data-quality flags, etc. Anyone working
with data from Environment Canada (reference 2) is advised to use \code{\link[=read.met]{read.met()}}
instead of the present function.
