Just released an updated version of our ‘aqp’ package for quantitative soils investigations, available on CRAN and R-Forge. Some of the major changes are listed below:

from the aqp NEWS file: -------------------------- aqp 0.98-1 (2010-11-23) -------------------------- * added basic demo: demo(aqp) * soil.slot() now computes aggregate probabilities over user-defined segments * re-write of weighted profile aggregation functions - aqp package now requires Hmisc package - using Hmisc::wtd.{mean,var,quantile} to compute values + better adjustment of weights when computing weighted SD + fixes long-standing bugs with wt. mean/SD when NA present in x_i and not in wt_i + weighted quantiles now computed * addition of new (experimental) S4 classes and methods - these are now in the aqp_S4 branch * added n.depth.ticks option to profile_plot() * profile_compare() algorithm stabilized, new default settings * removed code in profile_compare() that is now obsolete - note that this will cause changes to numerical classification of soil profiles
