Combine multiple multidesign objects — bind

This function row-binds the observation matrices and design data frames of several multidesign objects. All input multidesigns must share the same column design. Optionally, an identifier column can be added to track the source of each observation. Explicit cell masks are row-bound; if only some inputs are masked, unmasked inputs are treated as all observed.

Usage

bind_multidesign(..., .id = NULL)

Arguments

...: multidesign objects to combine
.id: optional name of an identifier column added to the design to indicate the origin multidesign

Value

A new multidesign object containing the concatenated data

Examples

X1 <- matrix(rnorm(10*5), 10, 5)
X2 <- matrix(rnorm(10*5), 10, 5)
md1 <- multidesign(X1, data.frame(cond = rep("A", 10)))
md2 <- multidesign(X2, data.frame(cond = rep("B", 10)))
combined <- bind_multidesign(md1, md2)
combined_id <- bind_multidesign(md1, md2, .id = "source")
