Different high-level graphics functions for displaying large datasets, displaying circular data in a very flexible way, finding local maxima, brewing color ramps, drawing nice arrows, zooming 2D-plots, creating figures with differently colored margin and plot region.  In addition, the package contains auxiliary functions for data manipulation like omitting observations with irregular values or selecting data by logical vectors, which include NAs. Other functions are especially useful in spectroscopy and analyses of environmental data: robust baseline fitting, finding peaks in spectra, converting humidity measures.

An Interactive Detector for Spatial Associations
Method of interactive detector for spatial associations (IDSA).
IDSA is used to quantify the power of interactive determinant (PID)
between a spatial response variable and explanatory variables.
IDSA is developed based on methods of spatial heterogeneity.

A sophisticated pipeline for processing
high-resolution LC/MS data to extract signals of organic compounds. The
package performs isotope pairing, peak detection, alignment, RT correction,
gap filling, peak annotation and visualization of extracted ion chromatograms and total ion chromatograms.
