tt: Convert a vector, matrix, or array to a tidytensor type.
In oneilsh/tidytensor: TidyTensor

Description Usage Arguments Details Value See Also Examples

tt() is a convenience shorthand for as.tidytensor(). Given a vector, matrix, or array, returns a tidytensor. If given a vector, converts to a 1-d array supporting dim(), matrices are left as matrices, and in all cases the class 'tidytensor' is added.

1	tt(x, ...)

`x`	input to convert to a tidytensor.
`...`	additional arguments to be passed to or from methods (ignored).

Matrices are synonymous with 2-d arrays, so these are left as is. Vectors are converted to 1-d arrays so that they can support dim().

# From an array (representing e.g. 30 26x26 images (30 sets of 26 rows of 26 pixels))
a <- array(rnorm(30 * 26 * 26), dim = c(30, 26, 26))
t <- tt(a)
