This function attaches XY coordinates to a data frame based on a spatial
object containing the coordinates. It performs a left join operation to
match the coordinates with the corresponding locations in the data frame.
     
    
    Usage
    attach_xy(data_full, data_sf, locs_id = "site_id", time_id = "time")
 
     
    
    Arguments
- data_full
 
The full data frame to which XY coordinates will
be attached.
 
- data_sf
 
The spatial object containing the XY coordinates.
 
- locs_id
 
The column name in the spatial object that represents the
location identifier.
 
- time_id
 
The column name in the data frame that represents the time
identifier.
 
 
    
    Value
    A data frame with the XY coordinates attached.
