\title{Add a seasonal component with specified period, number of Fourier
components, and prior scale.}
\usage{
add_seasonality(m, name, period, fourier.order, prior.scale = NULL)
}
\arguments{
\item{m}{Prophet object.}

\item{name}{String name of the seasonality component.}

\item{period}{Float number of days in one period.}

\item{fourier.order}{Int number of Fourier components to use.}

\item{prior.scale}{Float prior scale for this component.}
}
\value{
The prophet model with the seasonality added.
}
\description{
Increasing the number of Fourier components allows the seasonality to change
more quickly (at risk of overfitting). Default values for yearly and weekly
seasonalities are 10 and 3 respectively.
}
\details{
Increasing prior scale will allow this seasonality component more
flexibility, decreasing will dampen it. If not provided, will use the
seasonality.prior.scale provided on Prophet initialization (defaults to 10).
