Documentation for Eidos function exists
, which is a method of
Eidos
.
Note that the R function is a stub, it does not do anything in R (except bring
up this documentation). It will only do
anything useful when used inside a slim_block
function further
nested in a slim_script
function call, where it will be translated into valid SLiM code as part of a
full SLiM script.
eidos_exists(symbol)
An object of type string. See details for description.
An object of type logical.
Documentation for this function can be found in the official SLiM manual: page NA.
Returns a logical vector indicating whether symbols exist. If a symbol has been defined as an intrinsic Eidos constant like T, INF, and PI, or as a Context-defined constant like sim in SLiM, or as a user-defined constant using defineConstant(), or as a variable by assignment, this function returns T. Otherwise, the symbol has not been defined, and exists() returns F. This is commonly used to check whether a user-defined constant already exists, with the intention of defining the constant if it has not already been defined. A vector of symbols may be passed, producing a vector of corresponding results.
This is documentation for a function in the SLiM software, and has been reproduced from the official manual, which can be found here: http://benhaller.com/slim/SLiM_Manual.pdf.
