Plot the experimental points of each trajectory with the lines fitted by nls / nlsrk

1 2 |

`x` |
A "nls" object obtained with |

`data` |
a data.frame with only three columns named (imperatively) t, y, traj in that order |

`maintitle` |
Title for the graph |

`...` |
optional parameters for plot |

syslin
Minimal and preliminary implementation of a plot method for "nls" objects obtained by Runge-Kutta 4 resolution of a set of ODE. The symbols of the experimental points are chosen autom)tically according to the formula pch=19+data$traj. Then, the first trajectory is drawn with pch=20 (black dot), the next with pch=21 (empty circles), etc... see `plot`

(`options`

) and `par`

for details. Similarily, the lines of the fitted solutions are drawn in a color defined automatically according to the formula col=data$traj. The first trajectory is drawn in black (col=1), the next in red (col=2), etc...
Any object of type "nls" is accepted by the program, but if it does not result of the use of evrunge, inpredictible errors will occur.
