   \item{x}{ Integer, numeric or logical vector, coerced to numeric, on which sliding window calculates an aggregate function. It supports vectorized input, then it needs to be a \code{data.table}, \code{data.frame} or a \code{list}, in which case a rolling function is applied to each column/vector. }
-  \item{n}{ Integer, non-negative, rolling window size. This is the \emph{total} number of included values in aggregate function. In case of an adaptive rolling function window size has to be provided as vector for each indivdual value of \code{x}. It supports vectorized input, then needs to be a vector, or in case of an adaptive rolling a \code{list} of vectors. }

   \item{fill}{ Numeric; value to pad by. Defaults to \code{NA}. }
   \item{algo}{ Character, default \code{"fast"}. When set to \code{"exact"}, a slower (but more accurate) algorithm is used. It suffers less from floating point rounding errors by performing an extra pass, and carefully handles all non-finite values. It will use multiple cores where available. See Details for more information. }
   \item{align}{ Character, specifying the "alignment" of the rolling window, defaulting to \code{"right"}. \code{"right"} covers preceding rows (the window \emph{ends} on the current value); \code{"left"} covers following rows (the window \emph{starts} on the current value); \code{"center"} is halfway in between (the window is \emph{centered} on the current value, biased towards \code{"left"} when \code{n} is even). }
