Replacing NAs with interpolated values
Hi there, I've got this vector: -84 -87 -90 -90 -89 -86 NA NA NA NA NA NA NA NA NA NA NA NA -96 -99 -100 -99 -96 -92 -89 -87 -87 -88 -90 -92 -94 -95 -96 -97 -97 -97 -96 -95 Is there a function in R which replaces the NAs with "interpolated" values between -86 and -96?
maybe something like
x <- c(1,2,NA, NA, NA, 10) indx <- which(is.na(x)) x[is.na(x)] <- mean(c(x[indx[1]-1], x[indx[length(indx)]+1])) x
[1] 1 2 6 6 6 10 where `mean' is to be replaced with your interpolation :-) Torsten
