Changes in version 2.0.0

CRAN release: 2023-08-16

  • MAJOR REFACTOR: the update to version 2.0.0 includes many major changes that are designed to improve the speed, reliability, and reproducibility of {EGAnet}. The goal of these changes are to eliminate common errors and streamline the code in the package to prevent future error cases. There are several function additions that are provided to facilitate modular use of the {EGAnet} package

  • INTERNALS: function-specific internal functions and S3methods are now located in their respective .R files rather than elsewhere (e.g., “utils-EGAnet.R”)

  • SWAP: internal script usage of “utils-EGAnet.R” depracated for “helper.R” functions that are used across the package (no visible changes for the user)

  • NOTE: default objective function for Leiden algorithm is set to “modularity”

  • NOTE: default for Louvain unidimensional method is set to single-shot unless argument “consensus.method” or “consensus.iter” is specified

  • ADD: stricter *apply functions that are roughly equivalent to *apply but have stricter inputs/outputs (uses vapply as foundation; often, slightly faster)

  • ADD: community.consensus to apply the Consensus Clustering approach introduced by Lancichnetti & Fortunato (2012). Currently only available for the Louvain algorithm

  • ADD: community.detection to apply community detection algorithms as a standalone function

  • ADD: convenience function to convert an {igraph} object to a standard matrix (igraph2matrix)

  • ADD: modularity to compute standard (absolute values) and signed modularity (implemented in C)

  • ADD: polychoric.matrix to compute categorical correlations (implemented in C); handles missing data (“pairwise” or “listwise”) as well as empty cells in the joint frequency table (see documentation: ?polychoric.matrix)

  • ADD: auto.correlate now computes all correlations internally and no longer depends on external functions; categorical correlations are C based and bi/polyserial correlations are a simplified and vectorized version of {polycor}’s polyserial; substantial computational gains (between 10-25x faster than previous use of {qgraph}’s cor_auto)

  • ADD: network.estimation to handle all network estimation in {EGAnet}; includes Bayesian GGM from {BGGM} for more seamless incorporation of BEGA

  • ADD: community.unidimensional to apply different unidimensional community detection approaches; makes unidimensional community detection more modular and flexible

  • ADD: basic (internal) function to handle all network plots to keep changes centralized to a single function; extends flexbility to handle all {GGally}’s ggnet2 arguments

  • ADD: implemented reproducible parametric bootstrapping and random sampling (see for more details)

  • ADD: implemented reproducible resampling bootstrapping and random sampling (see for more details)

  • ADD: reproducible bootstrapping with seed setting that does not affect R’s seed and RNG (user’s seed will not be affected and will not affected bootstrapping seeds)

  • ADD: community.homogenize as a core function rather than internal (previously homogenize.membership); about 2.5x faster than the original version

  • ADD: convert2tidygraph for ggraph and tidygraph support – thanks to Dominique Makowski!

  • ADD: “multilevel” plotting support for hierEGA (only used when scores = "network" since factor scores don’t directly align with EGA detected dimensions)

  • ADD: internal functions shuffle and shuffle_replace to replace sample with and without replacement; performed in C and allows seed setting independent of R (about 2-3x faster)

  • ADD: xoshiro256++ PRNG for higher quailty random number generation, permutation, and resampling (~2x faster than runif and sample); based in C

  • ADD: Ziggurat method for random normal generation over top xoshiro256++ (2-5x faster than rnorm); based in C

  • ADD: configural invariance was added to invariance (see Details section)

  • ADD: genTEFI to compute the Generalized Total Entropy Fit Index solely; tefi serves as a general function to compute TEFI for all *EGA classes

  • REMOVE: signed.louvain until reproducibility can be sorted

  • REMOVE: methods.section and utils-EGAnet.methods.section to avoid space issues in ./R directory (1MB)

  • UPDATE: EBICglasso.qgraph and TMFG were optimized; TMFG is now 2x faster

  • UPDATE: TMFG can now directly estimate a GGM with the argument ‘partial = TRUE’; implements the Local-Global Inversion method from Barfuss et al. (2016)

  • UPDATE: switched on “Byte-Compile” (byte-compiles on our end and not when the user installs)

  • UPDATE: EGA.estimate and EGA core functions have been updated for seamless use with more basic functions network.estimation and community.* functions

  • UPDATE: S3method updates for EGA.estimate and EGA to provide estimation information

  • UPDATE: updated to be compatiable with all updates to EGA.estimate (other optimizations were implemented such as direct communtiy detection application and unique solution finding)

  • UPDATE: tefi updated with several checks (slightly slower for correlation matrix but much faster with raw data; includes data/matrix checks)

  • UPDATE: entropyFit uses more effective vectorization (about 5-7x faster)

  • UPDATE: Embed and glla made to be more efficient and includes an internal glla_setup function to avoid the same matrix calculations for every participant in a sample for dynEGA

  • UPDATE: riEGA updated to be compatiable with all lower-level updates (slightly faster)

  • UPDATE: wto updated to be fully vectorized (about 12x faster)

  • UPDATE: totalCor and totalCorMat updated to be fully vectorized (about 10x faster)

  • UPDATE: implemented internal for more efficient data frame initialization when all values in data frame are the same

  • UPDATE: bootEGA allows flexibility to add any arguments from any EGA* functions; much faster due to optimizations across all functions (“resampling” is nearly as fast as “parametric”)

  • UPDATE: support for and riEGA added to bootEGA (support for hierEGA will be coming soon…)

  • UPDATE: itemStability has been updated and runs about 2.5x faster due to community.homogenize; S3methods were added; greater flexibility available in plotting but not much support (e.g., error checking) yet

  • UPDATE: dimensionStability has been updated and maintains speed gains from itemStability

  • UPDATE: dynEGA.ind.pop now calls dynEGA with level = c("individual", "population"); legacy dynEGA.ind.pop class is maintained across ergodicity functions

  • UPDATE: ergoInfo is about 2x faster

  • UPDATE: jsd received several internal functions to expedite procedures in infoCluster and jsd.ergoInfo

  • UPDATE: net.loads now includes ‘loading.method’ argument to allow for reproducibility with “BRM” implementation (and version 1.2.3); “experimental” implementation includes rotations alternative signs and cross-loading computation (potential future default)

  • UPDATE: net.scores is much simpler (internally) and quicker; seamlessly integrates with net.loads

  • UPDATE: streamlined UVA (about 4x faster); fixed bugs related to reverse coding issues

  • UPDATE: tefi now handles all EGA* function objects including hierEGA which computes generalized TEFI

  • UPDATE: documentation for all functions have been thoroughly revised to provide better instruction on how to use functions and their expected inputs

  • DEPENDENCY: removed {network} because it is no longer used for plotting; switched {sna} to IMPORTS rather than SUGGESTS

  • DEPENDENCY: removed {rstudioapi} from ‘Suggests’ because it was used in colortext and used in the package

  • DEPENDENCY: removed {matrixcalc} because it was only used for trace of a matrix (own internal function is used)

  • DEPENDENCY: {future} and {future.apply} are used for parallelization (better integration); includes internal function to check for available memory to not break in big data cases

  • DEPENDENCY: {progress} and {progressr} are used for progress bars (in parallelization)

  • DEPENDENCY: removed {psychTools} from ‘Suggests’ which was only used in examples
