prospectr - version 0.2.6 (Chicago)

read_nircal(): non-utf characters in sample IDs are properly handled (before some IDs were wrongly converted into NAs).Non-UTF8 characters are now converted to their corresponding codes.

Documentation is now compatible with HTML5.

New features

• The kenStone function now includes a new feature that allows to initialize the calibration sample search with a user-defined subset of observations (which are to be included in the final calibration subset). Thanks to Thorsten Behrens and Philipp Baumann for suggesting this feature.

• The gap-segment derivatives (gapDer) function now allows for high order derivatives. In previous versions the function only allowed up to derivatives of 4th order, in this version the the function accepts as derivative order any integer larger than 1.

Improvements and fixes

• binning()a bug in the creation of the binning groups has been fixed. This bug is in fact inherited from a problem in the findInterval() function. The breaks (given in the vec arument) might get corrupted when they contain many decimal places. These breaks (in vec) are used to define the final bins. The problem in the binning function was that when a frequency variable (e.g. wavelength) was exactly on the left of the bin range the variable was assigned to the next bin. In some cases this lead to small discrepancies in the in the computation of the mean of the bins.

• spliceCorrection() now accepts one or two values as input for the splice argument. Previously it only accepted a vector of length two. For example, now it corrrects for splice steps of spectra that originates from spectrometers with two detectors (i.e. it corrects for the potential abrupt transition betwteen the two detectors).

• An extra sanity check has been added to the read_nircal() function. The function evaluaes whether it is indeed a file properly produced by the BUCHI nircal software.

• There was a bug in the filter for the 3rd order derivative in gap segment derivative (gapDer) function. One of the factors in the filter had a wrong negative sign.

• There was a bug in the read_nircal function. It emerged only in some files and prevented the function from reading the Description field properly

Changes

• In the msc() function the argument reference_spc has been renamed to ref_spectrum to emphasize that its input must be is a vector and not a matrix of spectra.
