resevol 0.4.1.0
NEW FEATURES
- New
initial_inds argument for run_farm_sim
to continue a simulation from the final individuals of a previous run.
initial_inds can be a matrix or data frame
run_farm_sim now returns a list of three elements; the
third element is a matrix of all individuals and their traits in the
final time step, with column names attached, which can be passed
directly to initial_inds in a new run_farm_sim
call- When individuals are passed with
initial_inds,
generation time and individual IDs continue from the previous simulation
instead of resetting, so individuals remain uniquely identifiable across
chained runs
MAJOR CHANGES
- Population buffers are now swapped between time steps (double
buffering) instead of freed and re-allocated each step, greatly reducing
memory churn for large simulations
mine_gmatrix now brackets all random number draws with
GetRNGstate / PutRNGstate, fixing a hang and
degenerate random numbers when mine_gmatrix was the first
random number use in a fresh R session
BUG FIXES
rename_csv now renames output files directly instead of
reading and re-writing them, fixing intermittent corruption of large
individual output files- Edge effects no longer fall through to the toroidal wrap: leaky,
reflective, and sticky edges behaved like wrapping edges; leaky edges
now correctly remove individuals from the landscape
- Population buffers are now tracked by size and freed exactly once on
all simulation paths, fixing a memory leak and reads past the end of
buffers when populations went extinct
- Failed memory allocations now raise a clean R error instead of
crashing
mine_gmatrix now returns the lowest-stress network
found during the evolutionary search instead of a random tournament
winner- The mutation rate in the
mine_gmatrix evolutionary
search is now correctly applied; previously every network element was
mutated every generation
- Fixed an error in the
individuals_colnames example
OTHER
- Added tests for file renaming, edge effects, extinction, and passing
individuals between runs
resevol 0.4.0.5
BUG FIXES
- Validation of rotation type and rotation time now only applies when
rotation_type is not a custom matrix, so custom crop and
pesticide rotation matrices work as intended
resevol 0.4.0.4
DOCUMENTATION
- Added a reference for the evolutionary algorithm (Luke 2013) and
other documentation updates (issues 55, 56)
resevol 0.4.0.3
BUG FIXES
- Crop and pesticide rotation type is no longer required to be 1, 2,
or 3 when a custom rotation matrix is supplied
resevol 0.4.0.2
DOCUMENTATION
- Updated package references and fixed a DOI issue reported on
win-builder
resevol 0.4.0.0
NEW FEATURES
- New function to add column names to individuals output CSV
- Custom file names are allowed for output files
- New argument
pesticide_threshold sets density threshold
for pesticide
- New argument
pesticide_threshold_delay delays pesticide
threshold
MAJOR CHANGES
- Default neutral allele number is now 10 instead of 1000
BUG FIXES
- Fixed issue causing an error for scalar
food_consume or
pesticide_consume
- Fixed a bug that was causing farmers to not apply pesticide
resevol 0.3.4.0
NEW FEATURES
- New argument to model crop growth over time within a season
resevol 0.3.3.0
NEW FEATURES
- Vignettes included demonstrating advanced options for
simulations
resevol 0.3.2.0
NEW FEATURES
- New argument allowing users to set initialised means for evolving
traits
resevol 0.3.1.0
MAJOR CHANGES
- Evolutionary algorithm termination criteria now based on mean
stress
NEW FEATURES
- New function to evaluate the stress of mined gmatrices
resevol 0.3.0.1
NEW FEATURES
- Custom landscapes allowing flexible structure to land types
- More flexible rotation of pesticides and crops on landscapes
resevol VERSION 0.2.0.9
BUG FIXES
- Fixed a memory issue causing a CRAN ERROR on Windows ix86
