This document is based on the NetLogo
Dictionary. It lists all the entries in the NetLogo Dictionary
(i.e., NetLogo primitives) and informs the best replacements to
use in R. Are suggested as replacements, functions from the
NetLogoR package, as well as functions from the R software
and of other packages (indicated below). To find how to use these
functions, please refers to their documentation by using
help("nameFunction").
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”. The NetLogo primitives not implemented should not prevent
the users from building individual-based models involving patches and
turtles.
For 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.

function is one of the function arguments that need to be

provided in a NetLogoR function, they all execute the

time.

is used to store the time (e.g., time <- 0;
