sparse_sd {sparsevctrs} | R Documentation |
Calculate standard diviation from sparse vectors
Description
Calculate standard diviation from sparse vectors
Usage
sparse_sd(x, na_rm = FALSE)
Arguments
x |
A sparse numeric vector. |
na_rm |
Logical, whether to remove missing values. Defaults to |
Details
This function, as with any of the other helper functions assumes that the
input x
is a sparse numeric vector. This is done for performance reasons,
and it is thus the users responsibility to perform input checking.
Much like sd()
it uses the denominator n-1
.
Value
single numeric value.
Examples
sparse_sd(
sparse_double(1000, 1, 1000)
)
sparse_sd(
sparse_double(1000, 1, 1000, default = 1)
)
sparse_sd(
sparse_double(c(10, 50, 11), c(1, 50, 111), 1000)
)
sparse_sd(
sparse_double(c(10, NA, 11), c(1, 50, 111), 1000)
)
sparse_sd(
sparse_double(c(10, NA, 11), c(1, 50, 111), 1000),
na_rm = TRUE
)
