Row (column) standard deviations for dbMatrix objects

Source: R/operations.R
sds.Rd

Calculates the standard deviation for each row (column) of a matrix-like object.

Usage

# S4 method for class 'dbDenseMatrix'
colSds(
  x,
  rows = NULL,
  cols = NULL,
  na.rm = FALSE,
  center = NULL,
  ...,
  useNames = TRUE
)

# S4 method for class 'dbSparseMatrix'

  x,
  rows = NULL,
  cols = NULL,
  na.rm = FALSE,
  center = NULL,
  ...,
  useNames = TRUE
)

# S4 method for class 'dbDenseMatrix'
