# plot.funData: A method to plot 'funData' objects In gmfd: Inference and Clustering of Functional Data

## Description

This function performs the plot of a functional dataset stored in an object of class `funData`.

## Usage

 ```1 2``` ```## S3 method for class 'funData' plot(x, ...) ```

## Arguments

 `x` the univariate functional dataset in form of `funData` object. `...` additional graphical parameters to be used in plotting functions
