Cross-product with a vector
Cross-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_cprodVec( obj.bed, y.row, ind.row = rows_along(obj.bed), ind.col = cols_along(obj.bed), center = rep(0, length(ind.col)), scale = rep(1, length(ind.col)), ncores = 1 )
obj.bed |
Object of type bed, which is the mapping of some bed file.
Use |
y.row |
A vector of same size as |
ind.row |
An optional vector of the row indices (individuals) that
are used. If not specified, all rows are used. |
ind.col |
An optional vector of the column indices (SNPs) that are used.
If not specified, all columns are used. |
center |
Vector of same length of |
scale |
Vector of same length of |
ncores |
Number of cores used. Default doesn't use parallelism. You may use nb_cores. |
