Read in real world data from X and y. — rwd_dgp • dgpoix

Read in real world data from X and y.

Usage

rwd_dgp(
  X,
  y,
  support = NULL,
  data_split = FALSE,
  train_prop = 0.5,
  return_values = c("X", "y")
)

Arguments

X: Data matrix or data frame.
y: Response vector.
support: Vector of feature indices in the true support of the DGP.
data_split: Logical; if TRUE, splits data into training and test sets according to train_prop.
train_prop: Proportion of data in training set if data_split = TRUE.
return_values: Character vector indicating what objects to return in list. Elements in vector must be one of "X", "y", "support".

Value

A list of the named objects that were requested in return_values. See brief descriptions below.

X: A data.frame.
y: A response vector of length nrow(X).
support: A vector of feature indices indicating all features used in the true support of the DGP.

Note that if data_split = TRUE and "X", "y" are in return_values, then the returned list also contains slots for "Xtest" and "ytest".

Examples

# read in iris data
iris_data <- rwd_dgp(X = iris %>% dplyr::select(-Species), y = iris$Species)
