stitch: Concatenate two or more tidytensors to create a new one with...

In oneilsh/tidytensor: TidyTensor

Description

Given multiple tidytensors of the same shape except the first rank, concatenates them together to create a tidytensor of the same shape, but larger in the first. For example, c(x, y, z) where x and have shape [2, 3, 5] and z has shape [10, 3, 5] returns a new tidytensor of shape [14, 3, 5].

Usage

stitch(...)

Arguments

...	a number of tidytensors of the same shape, or a single list of them.

Details

All input tidytensors must have the same shape except for the first rank. If the input ranknames conflict, only those of the first input tidytensor will be used, and a warning will be generated.

Value

a new tidytensor.

Examples

# Three tidytensors of the same shape
t1 <- as.tidytensor(array(1:(3 * 4 * 5), dim = c(3, 4, 5)))
t2 <- as.tidytensor(array(10 * 1:(3 * 4 * 5), dim = c(3, 4, 5)))
t3 <- as.tidytensor(array(100 * 1:(3 * 4 * 5), dim = c(3, 4, 5)))
ranknames(t1) <- c("sample", "row", "col")
ranknames(t2) <- c("sample", "row", "col")
ranknames(t3) <- c("sample", "row", "col")
t4 <- stitch(t1, t2, t3)
print(t4)

list_example <- list(t1, t2, t3)
t5 <- stitch(list_example)
print(t5)
