Product between a "bed" object and a vector.

Missing values are replaced by 0 (after centering), as if they had been imputed using parameter center.

bed_prodVec(
obj.bed,
y.col,
ind.row = rows_along(obj.bed),
ind.col = cols_along(obj.bed),
center = rep(0, length(ind.col)),
scale = rep(1, length(ind.col))
)

## Arguments

obj.bed A bed object. A vector of same size as ind.col. An optional vector of the row indices that are used. If not specified, all rows are used. Don't use negative indices. An optional vector of the column indices that are used. If not specified, all columns are used. Don't use negative indices. Vector of same length of ind.col to subtract from columns of X. Vector of same length of ind.col to divide from columns of X.

## Value

$$X \cdot y$$.

## Examples

bedfile <- system.file("extdata", "example.bed", package = "bigsnpr")
obj.bed <- bed(bedfile)

y.col <- rep(1, ncol(obj.bed))
str(bed_prodVec(obj.bed, y.col))#>  num [1:517] 2841 2916 2842 2835 2872 ...
