internal function

Description

internal function

Usage

EndRule(x, y, k, dimx,
             endrule=c("NA", "trim", "keep", "constant", "func"), 
             align = c("center", "left", "right"), Func, ...)

Arguments

`x`	numeric vector of length n
`k`	width of moving window; must be an integer between one and n.
`dimx`	original dimension of x (usually `dim(x)`) used to choose dimentions of the output.
`endrule`	character string indicating how the values at the beginning and the end, of the data, should be treated. Only first and last `k2` values at both ends are affected, where `k2` is the half-bandwidth `k2 = k %/% 2`. `"mad"` - applies the mad function to smaller and smaller sections of the array. Equivalent to: `for(i in 1:k2) out[i]=mad(x[1:(i+k2)])`. `"trim"` - trim the ends; output array length is equal to `length(x)-2*k2 (out = out[(k2+1):(n-k2)])`. This option mimics output of `apply` `(embed(x,k),1,FUN)` and other related functions. `"keep"` - fill the ends with numbers from `x` vector `(out[1:k2] = x[1:k2])`. This option makes more sense in case of smoothing functions, kept here for consistency. `"constant"` - fill the ends with first and last calculated value in output array `(out[1:k2] = out[k2+1])` `"NA"` - fill the ends with NA's `(out[1:k2] = NA)` `"func"` - same as `"mad"` option except that implemented in R for testing purposes. Avoid since it can be very slow for large windows.
`y`	numeric vector of length n, which is partially filled output of one of the `run` functions. Function `EndRule` will fill the remaining beginning and end sections using method chosen by `endrule` argument.
`align`	specifies whether result should be centered (default), left-aligned or right-aligned.
`Func`	Function name that `EndRule` will use in case of `endrule="func"`.
`...`	Additional parameters to `Func` that `EndRule` will use in case of `endrule="func"`.
