Hello, I am trying to figure out how to make a bode plot (a.k.a. bode diagram) in ggplot2. An example of such a diagram can be found here: http://meweb.ecn.purdue.edu/~me475/ctm/freq/bode2.GIF The example above shows the gain and phase characteristic of a linear system. In my case, I would like to compare visually several systems on the same diag...

Dear All I hope my question is relevant on this forum, else very sorry for the disturbance I want to simply plot a bode diagram of a siso model using the 'bodeplot' command in the control package fail due to error in 'issiso' evaluation...

...e.com) b) Using [-pi,+pi) is not "wrong"... it is numerically more precise, though it may not convey what you would prefer to convey. c) The general case with poles and zeroes is more complicated than just adding the order of your system. Do a search on "winding number" "bode" But if by inspection you think that shortcut will work for your system then do what you need to. d) If implementing a more general alternative solution is your itch, I am sure the maintainer of this _contributed package_ would welcome patches to add features.

By any chance are there any R packages that assist in producing Bode Plots and performing Bode analysis? Thanks again for any feedback and insights.

FWIW I can reproduce on macOS with R 3.5.1. A smaller example: system2("ls", timeout = 5); x <- sample(1:1E8) If I try to interrupt R while that sample call is running, R itself is closed.

...ns over to R and hopefully into a package, so I am curious if nargin and nargout work with R functions. Here is kind of an example of where I need to head in order to port "control-1.0.11" from Octave over to R. The Octave "control-1.0.11" package has the capability to produce bode plots of transfer functions. I hope to post this package once the port over to R is complete.
