New version of our ‘aqp’ package for quantitative soils investigations, available on CRAN (version 0.99-5) and R-Forge (0.99-8). Some of the major changes are listed below:
-------------------------- aqp 0.99-8 (2011-09-14) --------------------------
* soil.slot() will now accept boundaries defining a 'slab' over which aggregates are computed
* soil.slot.multiple() now cleanly wraps soil.slot(), accepting all arguments
- these two changes make it possible to ask:
"what is the wt. mean value of some property within this slab, and among these groups?"
- soil.slot.multiple() now uses a formula interface: NOTE that this will break existing scripts (sorry)
-------------------------- aqp 0.99-7 (2011-09-01) --------------------------
* new functions for getting data out of PedonPC (MS Access) databases [windows only for now]
- get_site_data_from_pedon_db() : site and pedon aggregate data
- get_hz_data_from_pedon_db() : horizon level data
- get_colors_from_pedon_db() : formats and mixes multiple colors / horizon
+ implemented in mix_and_clean_colors()
* test_hz_logic() : basic function for testing horizon logic, returns TRUE/FALSE by ID
* parallel operations now NON-functional, while we wait for plyr to support doSMP...
* new ID plotting style for profile_plot() : handy when plotting large collections and/or long IDs
-------------------------- aqp 0.99-4 (2011-08-15) --------------------------
* code and documentation clean-up
* Soil Sata Access (SDA) query functions have been added
- mapunit_geom_by_ll_bbox() : get map unit geometry by bounding box
- MUKEYS_by_ll_bbox() : get map unit keys by bounding box
- SDA_query() : retrieve soil tabular data via query written in SQL
* additional customizations added to profile_plot
* two new sample data sets + examples
