The created turtles must be assigned to an object before they can run some functions.Ĭreate-: createTurtles() from NetLogoR. create-turtles (crt): createTurtles() from NetLogoR.The created turtles must be assigned to an object before they can run some functions.Ĭreate-links-from: links not implemented.Ĭreate-links-with: links not implemented. To reset objects to 0 instead, reassign the objects (e.g., nameObject : createOTurtles() from NetLogoR. See the NetLogoR dictionnary entries for clear-globals, clear-ticks, clear-turtles, clear-patches, clear-drawing, clear-all-plots, and clear-output.Ĭlear-all-plots: graphics.off() closes all external plot windows opened and clears the plot window of RStudio.Ĭlear-globals: rm() removes the specified objects (which can be of any class) from the R environment, these objects do not longer exist afterwards. Use deg() from CircStats to convert the result in degrees.Ĭlear-all (ca): not implemented. To execute a function similarly as ask-concurrent, the function needs to be provided with one agent at the time.Īt-points: turtlesAt() from NetLogoR or patchAt() from NetLogoR.Ītan: atan2(), returns value in radians. When multiple agents are provided in a NetLogoR function, they all execute the function at the same time. ![]() The agents running a NetLogoR function is one of the function arguments that need to be provided.Īsk-concurrent: not implemented. Use deg() from CircStats to convert the result in degrees.Īsk: not implemented. Use deg() from CircStats to convert the result in degrees.Īrithmetic operators: +, *, -, /, ^,, = or = (depends if it is for setting or testing), !=, =.Īsin: asin(), returns value in radians. The NetLogo primitives not implemented should not prevent the users from building individual-based models involving patches and turtles.įor the inverse dictionary ( i.e., to find the NetLogo equivalents of the NetLogoR functions) please look at the NetLogoR documentation as the links to NetLogo Dictionary entries for the equivalent primitives are provided in the “See Also” section of each NetLogoR function.Īcos: acos(), returns value in radians. When no NetLogoR function was built to translate a NetLogo primitive and that, to our knowledge, no R function (or from other packages) could easily recreate the primitive, we indicated “not implemented”. ![]() To find how to use these functions, please refers to their documentation by using help("nameFunction"). Are suggested as replacements, functions from the NetLogoR package, as well as functions from the R software and of other packages (indicated below). It lists all the entries in the NetLogo Dictionary ( i.e., NetLogo primitives) and informs the best replacements to use in R. Follow the above link to browse the group.This document is based on the NetLogo Dictionary. There you can discuss thoughts and questions about NetLogo with other users via email or the web. If you have more questions in the future I encourage you to make use of our main online user community list The NetLogo model in the attached zipped file gives a simple example of a car that stops at yellow lights and not green lights. If you create a procedure called move for cars, you can get them all to move using the command If you create breeds for cars and lights, you can test if a car is on the same patch as other cars or lights using You got an error message because you did not define any breeds.Ī quick way to open an example of using breeds from the NetLogo Model Library is to type “_Breed” in the command center. If you want to learn about using breeds, here are some resources: ![]() Commands can be addressed to turtles of a breed. The angle brackets in is-? mean that the letters should be replaced by the actual name for a single member of the breed.īreeds are turtles that belong to a group. Then the correct syntax for the command you are looking for would be is-light? If a breed were defined in the code with the statement The error message appears because no breed has been defined. ![]() I will briefly explain why it is not a NetLogo bug, and then offer some programming ideas. Thanks for contacting us about your problem.
