\title{Combine measurement uncertainties by adding them in quadrature.}
\usage{
def.ucrt.comb(ucrt, log = NULL)
}
\arguments{
\item{ucrt}{Numeric data frame of uncertainties to be combined.}

\item{log}{A logger object as produced by NEONprocIS.base::def.log.init to produce structured log
output in addition to standard R error messaging. Defaults to NULL, in which the logger will be
created and used within the function.}
}
\value{
A data frame with a single numeric column:\cr
\code{ucrtComb} - combined measurement uncertainty resulting by adding in quadrature all the
uncertainties provided in the input data frame \code{ucrt}.
}
\description{
Definition function. Reads in a data frame of uncertainties and adds each row in quadrature.
NA values are NOT ignored.
}
\examples{
ucrt <- data.frame(ucrtA=c(1,2,1,1,2),ucrtB=c(5,6,7,8,9),stringsAsFactors=FALSE)
