Computes a weighted sum of a numeric vector.

1 | ```
weightedSum(x, w, na.rm = TRUE)
``` |

`x` |
a numeric vector containing the values whose weighted sum is to be computed. |

`w` |
a vector of weights the same length as x giving the weights to use for each element of x. Negative weights are treated as zero weights. Default value is equal weight to all values.# |

`na.rm` |
a logical value indicating whether NA values in x should be stripped before the computation proceeds, or not. If NA, no check at all for NAs is done. Default value is NA (for efficiency). |
