`vpts`

)Plot a time series of vertical profiles of class `vpts`

.

## S3 method for class 'vpts' plot( x, xlab = "time", ylab = "height [m]", quantity = "dens", log = TRUE, barbs = TRUE, barbs_height = 10, barbs_time = 20, barbs_dens_min = 5, zlim, legend_ticks, legend.ticks, main, barbs.h = 10, barbs.t = 20, barbs.dens = 5, ... )

`x` |
A vp class object inheriting from class |

`xlab` |
A title for the x-axis. |

`ylab` |
A title for the y-axis. |

`quantity` |
Character string with the quantity to plot,
one of ' |

`log` |
Logical, whether to display |

`barbs` |
Logical, whether to overlay speed barbs. |

`barbs_height` |
Integer, number of barbs to plot in altitudinal dimension. |

`barbs_time` |
Integer, number of barbs to plot in temporal dimension. |

`barbs_dens_min` |
Numeric, lower threshold in aerial density of individuals for plotting speed barbs in individuals/km^3. |

`zlim` |
Optional numerical atomic vector of length 2, specifying the
range of |

`legend_ticks` |
Numeric atomic vector specifying the ticks on the color bar. |

`legend.ticks` |
Deprecated argument, use legend_ticks instead. |

`main` |
A title for the plot. |

`barbs.h` |
Deprecated argument, use barbs_height instead. |

`barbs.t` |
Deprecated argument, use barbs_time instead. |

`barbs.dens` |
Deprecated argument, use barbs_dens_min instead. |

`...` |
Additional arguments to be passed to the low level image plotting function. |

Profile can be visualized in three related quantities, as specified
by argument `quantity`

:

- "
`dens`

" the aerial density of individuals. This quantity is dependent on the assumed radar cross section (RCS) in the

`x$attributes$how$rcs_bird`

attribute- "
`eta`

" reflectivity. This quantity is independent of the value of the

`rcs_bird`

attribute- "
`dbz`

" reflectivity factor. This quantity is independent of the value of the

`rcs_bird`

attribute, and corresponds to the dBZ scale commonly used in weather radar meteorology. Bioscatter by birds tends to occur at much higher reflectivity factors at S-band than at C-band- "
`DBZH`

" total reflectivity factor. This quantity equals the reflectivity factor of all scatterers (biological and meteorological scattering combined)

In the speed barbs, each half flag represents 2.5 m/s, each full flag 5 m/s, each pennant (triangle) 25 m/s

# locate example file: ts <- example_vpts # plot density of individuals for the first 500 time steps, in the altitude # layer 0-3000 m. plot(ts[1:500], ylim = c(0, 3000)) # plot total reflectivity factor (rain, birds, insects together): plot(ts[1:500], ylim = c(0, 3000), quantity = "DBZH")
