Converts a numeric vector into an ordinal one based on quantiles.
qvector(x, probs = seq(0, 1, 0.25), na.rm = FALSE, ...)
x |
a numeric vector. |
probs |
numeric vector of probabilities with values in [0, 1] used by quantile . |
na.rm |
logical, if true, any NA and NaN s are removed from x before the quantiles are computed. |
... |
further arguments passed to the function quantile . |
A numeric vector of length the same as the input vector, containing the respective (upper) quantile values.
