whittaker.raster returns 0 and 1 only

[fdetsch]

I'm trying to re-run a script I wrote a couple of months ago. Back then, I performed whittaker.raster (MODIS package version 0.10-18) on a 'RasterStack' consisting of GIMMS3g data (2000-2010; download from here) and everything worked just fine.

## load data into R
load("~/gimms_sample_data.RData")

## apply whittaker smoother
rst_wht <- 
  whittaker.raster(rst_trm, timeInfo = org_gimms, lambda = 6000, nIter = 3, 
                   removeOutlier = TRUE, threshold = 0.2, 
                   outDirPath = "data/rst/GIMMS3g/whittaker", overwrite = TRUE)

Unfortunately, my code (remained the same except for 'outlierThreshold') doesn't seem to work properly with 0.10-33. The operation finishes without raising an error, but the resulting raster layers consist of values 0 and 1 only.

## apply whittaker smoother
rst_wht <- 
  whittaker.raster(rst_trm, timeInfo = org_gimms, lambda = 6000, nIter = 3, 
                   removeOutlier = TRUE, outlierThreshold = 0.2, 
                   outDirPath = "data/rst/GIMMS3g/whittaker", overwrite = TRUE)

Fixed rounding issue with commit 4c7b88d. The reason for the observed behavior was that the former raster::dataType "FLT" is no longer available, but has been replaced e.g. with "FLT4S". See ?dataType for further information.

In order to solve this issue, the whittaker.raster function now tries to grep the "FLT" pattern in the corresponding data type of the provided 'vi' layers rather than checking for a fixed string, thus deactivating rounding when dealing with float data.
