The function plot_vts plots voltage vs time.
     
    
    Usage
    plot_vts(data, aggregate = TRUE, interval = 100)
 
    
    Arguments
    - data
- Dataframe containing columns for time and volts 
- aggregate
- TRUE/FALSE indicated whether to aggregate the data and
reduce the number of points by plotting only the mean over a set interval. 
- interval
- Integer indicating the number of points to aggregate
together if aggregate = TRUE. 
 
    
    Value
    
A voltage time series plot.
     
    
    Details
    If a large amount of data is fed in, it is recommended to aggregate
because plotting an excess of points is time intensive.
