Initialize Transformation for Hyperdesign

Method to initialize transformations (e.g., scaling, centering) for hyperdesign objects. Each block in the hyperdesign gets its own transformation object. Hyperdesigns with partial cell masks are rejected because preprocessors do not declare how masks transform. All-`TRUE` masks are reshaped with the output, while absent masks remain absent.

Usage

# S3 method for class 'hyperdesign'
init_transform(x, X, ...)

Arguments

x

A hyperdesign object

X

A preprocessing specification supported by `multivarious`, such as `multivarious::center()`.

...

Additional arguments (not used)

Value

A hyperdesign with transformed data and a preproc attribute containing the fitted preprocessing objects

Examples

d1 <- multidesign(matrix(rnorm(10*5), 10, 5),
                  data.frame(cond = rep(c("A","B"), 5)))
d2 <- multidesign(matrix(rnorm(10*5), 10, 5),
                  data.frame(cond = rep(c("A","B"), 5)))
hd <- hyperdesign(list(d1, d2))
hd_transformed <- init_transform(hd, multivarious::center())
