rray_squeeze: Squeeze an rray
In rray: Simple Arrays

Description Usage Arguments Details Value Examples

rray_squeeze() is conceptually similar to base::drop(), but it allows for the specification of specific dimensions to squeeze.

1	rray_squeeze(x, axes = NULL)

`x`	A vector, matrix, array or rray.
`axes`	An integer vector specifying the size 1 dimensions to drop. If `NULL`, all size 1 dimensions are dropped.

The dimension name handling of rray_squeeze() is essentially identical to drop(), but some explanation is always helpful:

Dimension names are removed from the axes that are squeezed. So squeezing a (2, 1, 2) object results in a (2, 2) object using the dimension names from the original first and third dimensions.
When all dimensions are squeezed, as in the case of (1, 1, 1), then the first dimension names that are found are the ones that are used in the (1) result.

x with the axes dropped, if possible.

# (10, 1) -> (10)
x <- rray(1:10, c(10, 1))
rray_squeeze(x)

# Multiple squeezed dimensions
# (10, 1, 1) -> (10)
y <- rray_reshape(x, c(10, 1, 1))
rray_squeeze(y)

# Use `axes` to specify dimensions to drop
# (10, 1, 1) -> drop 2 -> (10, 1)
rray_squeeze(y, axes = 2)

# Dimension names are kept here
# (10, 1) -> (10)
x <- rray_set_row_names(x, letters[1:10])
rray_squeeze(x)

# And they are kept here
# (1, 10) -> (10)
rray_squeeze(t(x))
