\arguments{
\item{exp}{Forecast array of multi-member time series, e.g., the NAO index 
of one experiment. The expected dimensions are 
c(members, start dates/forecast horizons). A vector with only the time 
dimension can also be provided. Only monthly or lower frequency time 
series are supported. See parameter freq.}

\item{obs}{Observational vector or array of time series, e.g., the NAO index 
of the observations that correspond the forecast data in \code{exp}.
The expected dimensions are c(start dates/forecast horizons) or 
c(1, start dates/forecast horizons). Only monthly or lower frequency time 
series are supported. See parameter freq.}

\item{toptitle}{Character string to be drawn as figure title.}

\item{ytitle}{Character string to be drawn as y-axis title.}

\item{monini}{Number of the month of the first time step, from 1 to 12.}

\item{yearini}{Year of the first time step.}

\item{freq}{Frequency of the provided time series: 1 = yearly, 12 = monthly,}

\item{expname}{Experimental dataset name.}

\item{obsname}{Name of the observational reference dataset.}

\item{drawleg}{TRUE/FALSE: whether to draw the legend or not.}

\item{fileout}{Name of output file. Extensions allowed: eps/ps, jpeg, png, 
pdf, bmp and tiff. \cr
Default = 'output_PlotBox.ps'.}

\item{width}{File width, in the units specified in the parameter size_units 
(inches by default). Takes 8 by default.}

\item{height}{File height, in the units specified in the parameter 
size_units (inches by default). Takes 5 by default.}

\item{size_units}{Units of the size of the device (file or window) to plot 
in. Inches ('in') by default. See ?Devices and the creator function of the 
corresponding device.}

\item{res}{Resolution of the device (file or window) to plot in. See 
?Devices and the creator function of the corresponding device.}

\item{...}{Arguments to be passed to the method. Only accepts the following
graphical parameters:\cr
ann ask bg cex.lab cex.sub cin col.axis col.lab col.main col.sub cra crt 
csi cxy err family fg fig font font.axis font.lab font.main font.sub lend

\value{
Generates a file at the path specified via \code{fileout}.

\description{
Produce time series of box-and-whisker plot showing the distribution of the 
members of a forecast vs. the observed evolution. The correlation between
forecast and observational data is calculated and displayed. Only works for 
n-monthly to n-yearly time series.
