predDF | R Documentation |
Build a data.frame
for prediction, where one variable varies and all
other variables are set to the reference value (median for continuous
variables).
predDF(object, ...)
## S3 method for class 'JointAI'
predDF(object, vars, length = 100L, ...)
## S3 method for class 'formula'
predDF(object, data, vars, length = 100L, ...)
## S3 method for class 'list'
predDF(object, data, vars, length = 100L, idvar = NULL, ...)
