pc.omitneg: An internal function

In lagged: Classes and Methods for Lagged Objects

An internal function

Description

An internal function

Usage

pc.omitneg(lags, maxlag)

Arguments

lags	todo: describe!
maxlag	todo: describe!

Details

pc.omitneg helps to implement dropping of negative indices in season-lag objects. It returns its first argument, lags, if all of its elements are non-negative. Otherwise, all elements of lags must be non-positive. In this case the function creates the vector 0:maxlag and drops the elements specified by lags. Note that the default indexing will not work properly since zero elements in an index are omitted (and there are such indices in season-lag objects).

Value

for pc.omitneg, a vector of lags (non-negative integers).

Examples

# ttmatToslPairs
# pc.omitneg
lagged:::pc.omitneg(0:5,10) # 0:5, unchagend since all values >= 0

lagged:::pc.omitneg(-(0:5),10) # 6:10, works like
(0:10)[-(0:5 +1)]     # same

# don't mix positive and negative numbers in pc.omitneg
## Not run: lagged:::pc.omitneg(c(0,2,3,-4,5), 10)
