SE-ABMs have been widely used by ecologists to study populations and communities with, for example, research on human–wildlife interactions (Chion et al. These models can include as many agent-level mechanisms as wanted and they are especially useful when population-level patterns are difficult to understand (DeAngelis and Grimm 2014). When they are ‘spatially-explicit’, there is an effect of the landscape and the fate of the entities is therefore constrained by their environment (McIntire et al. Population-level patterns emerge from the agent-level mechanism simulations (Railsback and Grimm 2012). These entities have state-dependent behaviors and they can interact with each other and/or their environment. Agent-based models are bottom–up models that simulate the fate of unique, autonomous entities. Movie-grab-interface: see package animation.Many scientific disciplines have shown great interests in spatially explicit agent-based models (SE-ABMs) (DeAngelis and Grimm 2014). movie-grab-view: see package animation.Use unlist() to transform a list into a vector prior using min(). element %in% nameList for lists and vectors grepl() for strings. Member?: pExist() or tExist(), both from NetLogoR to test patches or turtles existence in an agenset. Use unlist() to transform a list into a vector prior using median(). Use unlist() to transform a list into a vector prior using mean(). Use unlist() to transform a list into a vector prior using max(). The created turtles must be assigned to an object before they can run some functions.Ĭreate-temporary-plot-pen: not implemented.įile-open: read.table(), read.csv, load(), raster(), etc., depends on the file format.įirst: nameList] for lists substr(nameString, 1, 1) for strings.įoreach: for(i in 1:length(nameList)). 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.
Netlogo sprout windows#
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”.

Netlogo sprout software#
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. This document is based on the NetLogo Dictionary.
