asRow | R Documentation |

Turns a numeric vector into a matrix that has 1 row or 1 column. Part of NIMBLE language.

asRow(x) asCol(x)

`x` |
Numeric to be turned into a single row or column matrix |

In the NIMBLE language, some automatic determination of how to turn vectors into single-row or single-column matrices is done.
For example, in `A %*% x`

, where A is a matrix and x a vector, x will be turned into a single-column matrix unless
it is known at compile time that A is a single column, in which case x will be turned into a single-row matrix.
However, if it is desired that x be turned into a single row but A cannot be determined at compile time to be a single column,
then one can use `A %*% asRow(x)`

to force this conversion.
