Description Usage Arguments Details Value Functions Examples
This function returns a moving quantile of the given vector.
1 2 3 4 |
vec |
A numeric vector. |
n |
An integer: moving window size, with 1 as default |
prob |
A number: between 0 and 1, meaning prob quantile |
ss |
An integer: step size, only calculating at points with an equal distance ss. Namely, there are ss-1 number between each two 'consecutive' points |
na_rm |
logical. Should missing values (including NaN) be removed? |
sizeD |
logical. Only applied when ss > 1, it decides whether to get a result of smaller size. If sizeD = T, align does not affect the output. |
align |
A string denotes how to align the moving average, three options: "left", "middle", "right" |
Despite of Efficient computation, this function can return different kinds of moving quantile,
e.g. moving median(prob = 0.5), moving minimum(prob = 0),
and moving maximum(prob = 1). It can handle potential
missing values(NA or NaN) in the vec. When we move to one specific fragment, missing
values can be removed by setting na_rm = TRUERUE. If all values of this fragment is missing,
it will return NA.
In terms of the quantile algorithm, please consult type 7 in function
quantile
.
This function returns a vector whose length is the same as that of vec or is
ceiling
((L - n + 1)/ss), (when sizeD = T), where L is the
length of vec.
movQtr
: An function equivalent to movQt(..., align = "right")
