Creates a character matrix which specifies which effects to estimate and which effects to constrain to a non-zero value
blueprint(effects, use) A character matrix
A data frame that contains information on which cross-lagged effects to
estimate or constrain to a value other than zero. Each row
represents one effect. The effects object must have four
columns: column 1 has the variable names for the predictors,
column 2 has the variable names for the outcomes, column
3 has the names of the estimated effect or the value an unestimated
effect should be constrained to, and column 4 has information
on whether the effect should be estimated. This table can be
created by using the effectTable function
A vector with the variable names that will be used in the stability-informed model
