Shift a vector left or right.

Source: R/utils.R

Simple function to move the elements of a vector to earlier or later positions depending on the value of shift. Auxiliary to other functions, rather multipurpose.

shift.vector(x, shift = 0, fill = FALSE)

Arguments

x

vector.
shift

integer. Value < length(x). Default 0.
fill

Values to fill newly created positions, e.g. FALSE, NA, or 0.

Value

The vector x, shifted left or right.

Details

Nothing fancy here. This is used for example in Noumbissi() to match denominator ranges to numerator positions using logical vectors.
