Description Usage Arguments Details Value Functions Examples
This function returns A matrix: the first column is the position, the second column the input vector, and third column moving sum of the given vector. The weight argument is optional.

vec |
A numeric vector. |
pos |
A numeric vector with all integers. Its length must be the SAME as vec. N.B. We use integers to represent the (relative) positions of every point. |
n |
An integer: moving window size, with 1 as default |
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 |
w |
An optional weight vector of length n. It will be automatically normalized (sum to 1). |
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" |
This function can obtain the moving sum efficiently. It serves as somehow a generalized
version of movMeanUE
. The difference is that it will not automatically
normalized the weights vector, w argument.
If there is no missing value in vec, and w is normalized, which means
the sum of all elements is 1, this function will return a moving average.
For matrix details, please refer to details of movMeanUE
.
This function returns A MATRIX of size: L*3, where L is the length of vector, or
of size: L1*3, where L1 = ceiling
((nrow - n + 1)/ss),
(when sizeD = T). In the matrix, the first column denotes the position, the second column the
original vector, and the third column the moving average.
