Fast calculation of column- and row-wise quantiles of a matrix at a single probability. Implemented via compiled
code, it is much faster than the equivalent apply(data, 2, quantile, prob = p)
.
colQuantileC(data, p)
rowQuantileC(data, p)
A vector of length equal the number of columns (for colQuantileC
) or rows (for rowQuantileC
)
in data
containing the column- or row-wise quantiles.
a numerical matrix column-wise quantiles are desired. Missing values are removed.
a single probability at which the quantile is to be calculated.

At present, only one quantile type is implemented, namely the default type 7 used by R.
