\title{
  Plot Two Scores With Confidence Intervals In A Common Plot
}
\description{
  Plots two input variables havind the same dimensions in a common plot.
  One plot for all experiments.
  Input variables should have dimensions (nexp/nmod, nltime).
}
\usage{
  Plot2VarsVsLTime(var1, var2, toptitle = "", ytitle = "", monini = 1, 
                   freq = 12, nticks = NULL, limits = NULL, 
                   listexp = c("exp1", "exp2", "exp3"), 
                   listvars = c("var1", "var2"), biglab = F, hlines = NULL, 
                   leg = T, siglev = F, sizetit = 1, 
                   fileout = "output_plot2varsvsltime.eps", show_conf = T)
}

  }
  \item{leg}{
    T/F if legend should be added or not to the plot. Default = T.
  }
  \item{siglev}{
    T/F if significance level should replace confidence interval.
