fillGap: Fill a gap in an oce object

Description

Fill a gap in an oce object

Usage

fillGap(x, method=c("linear"), rule=1)

Arguments

x

an oce object.

method

to use; see Details.

rule

integer controlling behaviour at start and end of x. If rule=1, NA values at the ends are left in the return value. If rule=2, they are replaced with the nearest non-NA point.

Value

• A new oc object, with gaps removed.

Bugs

{Eventually, this will be expanded to work with any oce object. But, for now, it only works for vectors that can be coerced to numeric.} {If the first or last point is NA, then x is returned unaltered.} {Only method linear works now, and that argument is ignored at present.}

Details

Sequences of NA values, are filled by linear interpolation between the non-NA values that bound the gap.

Examples

library(oce)
# Integers
x <- c(1:2, NA, NA, 5:6)
y <- fillGap(x)
print(data.frame(x,y))
# Floats
x <- x + 0.1
y <- fillGap(x)
print(data.frame(x,y))
