Coerce a list of parameters to a long.param.df
long.param.df
It is possible to set input parameters using a specifically formatted
data.frame object. The first 3 columns of this data.frame must
be:
param: The name of the parameter. If this is a non-scalar parameter (a vector of length > 1), end the parameter name with the position on the vector (e.g.,"p_1","p_2", ...).value: the value for the parameter (or the value of the parameter in the Nth position if non-scalar).type: a character string containing either"numeric","logical", or"character"to define the parameter object class.
In addition to these 3 columns, the data.frame can contain any number
of other columns, such as details or source columns to document
parameter meta-data. However, these extra columns will not be used by
EpiModel.
