v3.0.2

Minor bug fix (#48: problem loading mix/consumer data in the GUI version)

v3.0.1

Fixed an error that applies with source data = means and the "Resid*Process" error structure (affects Wolves, Killer whale, and Isopod examples)

v3.0.0

Major update to MixSIAR, including:

• error structures now multivariate, with 3 options: "Residual only", "Residual * Process", "Process only (N=1)"
• fixed coding of fixed effects (cases with 2FE, 1FE + 1RE)
• new function plot_prior to plot uninformative vs. informative priors (included in GUI)
• new function calc_area to calculate Brett (2014) normalized surface area
• normalized continuous covariate
• MCMC chains given different initial values
• added new examples with fatty acids
• new manual

v2.1.3

Fixed a couple bugs that occurred with updated R packages:

• xyplot now explicitly from lattice package, as lattice::xyplot
• per mille sign issue with PDF (now use cairo_pdf from cairo package)

v2.1.2

Couple minor improvements from Jason Venkiteswaran:

• changed two file endings from .R to .r (caused error on Linux)
• changed % to the permil character for the labels in the plot_data function

v2.1.1

Bug fix:

• 5% and 25% quantiles were mixed up in the summary stats

Thanks to Jason Waite and Diana Lafferty for reporting!

v2.1

Updates from previous version (v2.0):

• Corrected implementation of fixed effects
• Added ability to input an informative prior (killer whale example in "mixsiar_script.r")

v2.0

NOTE: I have not yet updated the User Manual, but I thought they were important enough to release now. Stay tuned for the updated manual!

Important changes from the MixSIAR v1.0 code:

1. Several bug/error fixes
2. New scripted version, check out "mixsiar_script.r"
3. Altered the GUI function call to:

source("mixsiar_gui.r")
mixsiar_gui()

1. Added option for fixed effects
2. Separated OUTPUT button from RUN MODEL button
3. Simplified MCMC options (now choose from "test", "short", "long", etc. See "mixsiar_script.r" for details)

v1.0

Copy of MixSIAR software originally released in October 2013 on EcologyBox at http://conserver.iugo-cafe.org/user/brice.semmens/MixSIAR

Known bugs (fixed in v2.0):

• summary stats mixed up
• var.resid(iso,i) should have been var.resid(iso) (extra residual error terms)
• error: frac_sig2 not used (avoided by only allowing process or process+resid)
• 'colSds' not found (from matrixStats package)
• as.matrix() added to load_discr_data.r for n.iso=1 and n.re=1 case
