Generic function for filling NA values or specified positions.
na.fill(object, fill, ...) ## S3 method for class 'ts' na.fill(object, fill, ix, ...) ## S3 method for class 'zoo' na.fill(object, fill, ix, ...) ## Default S3 method: na.fill(object, fill, ix, ...) na.fill0(object, fill, ix = !is.na(object))

na.fill is a generic function for filling NA or indicated values.
It currently has methods for the time series classes "zoo" and "ts"
and a default method based on the "zoo" method.
Furthermore, na.fill0 works with plain vectors and "Date" objects.
It also works with "zoo" objects provided that no fill component is NULL.
z <- zoo(c(NA, 2, NA, 1, 4, 5, 2, NA))
na.fill(z, "extend")
na.fill(z, c("extend", NA))
na.fill(z, -(1:3))
na.fill(z, list(NA, NULL, NA))Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
