Quantile

Sample quantiles and col/row wise quantiles

Sample quantiles and col/row wise quantiles.

colQuantile(x,probs,parallel=FALSE)
rowQuantile(x,probs,parallel=FALSE)
Quantile(x,probs)

`x`	Numeric vector whose sample quantiles are wanted. NA and NaN values are not allowed in numeric vectors. For the col/row versions a numerical matrix.
`probs`	Numeric vector of probabilities with values in [0,1], not missing values. Values up to 2e-14 outside that range are accepted and moved to the nearby endpoint.
`parallel`	Do you want to do it in parallel in C++? TRUE or FALSE.

This is the same function as R's built in "quantile" with its default option, type = 7. We have also implemented it in a col/row-wise fashion.

The function will return a vector of the same mode as the arguments given. NAs will be removed.
