Create a Multiframe from a List

Creates a multiframe object from a list of observations and associated design information. A multiframe combines experimental design metadata with lazy-evaluated observations. Each element in the list must have consistent dimensions (same number of columns if matrices, or same length if vectors).

Usage

# S3 method for class 'list'
multiframe(x, y, ...)

Arguments

x

A list containing observations (matrices, arrays, or vectors)

y

A data frame containing design variables. Must have same number of rows as length of x

...

Additional arguments (currently unused)

Value

A multiframe object containing a design tibble with observation functions

Examples

# Create list of observations (matrices with same number of columns)
x <- list(
  matrix(1:12, 3, 4),  # 3x4 matrix
  matrix(13:24, 3, 4), # 3x4 matrix
  matrix(25:36, 3, 4)  # 3x4 matrix
)

# Create design information
y <- data.frame(
  condition = c("A", "B", "C"),
  block = 1:3
)

# Create multiframe
mf <- multiframe(x, y)

# Access first observation
obs1 <- mf$design$.obs[[1]]()

# View design information
print(mf$design)
#> # A tibble: 3 × 4
