[R-sig-Geo] AVHRR NDVI3g time series tool?

Hi all, shot in the dark here. But is there a prefabricated tool for
extracting the biweekly time series from  AVHRR NDVI3g for a particular
set of points? I can download all the data and process it myself but
wondering if there is a package that would make this easy. E.g., what I'd
like would be to have the biweekly NDVI time series from 1981 to 2015 for
these points without processing all the netcdf files:


require(sp)
pts <- data.frame(ID="NOCA","MORA","OLYM",
                  lat=c(48.776, 48.879,47.802),
                  long=c(-121.299,-121.726,-123.604))
coordinates(pts) <- ~lat+long


Can such a thing be easily done?

Thanks in advance for advice, Andy
