Create MxAlgebra object from a string
Create MxAlgebra object from a string
mxAlgebraFromString(algString, name = NA, dimnames = NA, ...)
algString |
the character string to convert into an R expression |
name |
An optional character string indicating the name of the object. |
dimnames |
list. The dimnames attribute for the algebra: a list of length 2 giving the row and column names respectively. An empty list is treated as NULL, and a list of length one as row names. The list can be named, and the list names will be used as names for the dimensions. |
