shiftData: Shift Data
In smwesten-usgs/recharge: Estimating Recharge with HYSEP, PART, and Recursive Digital Filter methods.

Returns a vector like the input, but with the position of the data shifted up or down.

1	shiftData(x, k = 1, fill = NA, circular = FALSE)

`x`	any vector.
`k`	a positive or negative whole number of positions to shift the data. Positive values shift data to a higher position and negative values shift data to a lower position.
`fill`	a scalar value like `x` used to fill in the first `k` positions or the last -`k` positions if `circular`=`FALSE`. Ignored if `circular`=`TRUE`. The default value is `NA`. If `x` is class "factor," then `fill` must be `NA` or a valid level in `x`.
`circular`	logical (`TRUE` or `FALSE`). If `TRUE`, then treat `x` as a circular buffer, rotating values from the end into the beginning if `k` is positive and vice versa if `k` is negative. If `FALSE`, then use the value of fill. The default value is `FALSE`.

A vector like x, with data shifted in position.

shiftData(1:5, k=1)
# [1] NA  1  2  3  4
shiftData(1:5, k=1, circ=TRUE)
# [1] 5 1 2 3 4
