Changes in version 2025-5-01 Version: ILSM 1.1.0 Many modifications were accepted and we added some new functions: {ig_icmotif_count}, {ig_icmotif_role}, etc Changes in version 2024-11-01 Version: ILSM 1.0.3.3 We added the function {node_icc}. We will temporarily suspend the development of node versatility within the multilayer network for function {node_cv}. Renamed the title: Analyze Interconnection Structure of Tripartite Interaction Networks. Changes in version 2024-08-04 Version: ILSM 1.0.3.2 We added the dataset: "PPH_Coltparkmeadow"!!! Such as: data(PPH_Coltparkmeadow). Changes in version 2024-7-13 Version: ILSM 1.0.3.1 We converted the functions {motif_count()}, {motif_role()}, {Node_versatility()}, {Prc()}, {Psc()}, and {Hc()} to {icmotif_count()}, {icmotif_role()}, {node_cv()}, {pc()}, {poc()}, and {hc()}. Split the processing of function {subnet_cor()} into two separate functions {coid()} and {cois()}. The function {subnet_cor()} is no longer used. Plotted the new definition of the multilayer interaction network.(Detailed in Vignettes). Updating!!! Changes in version 2024-4-27 Version: ILSM 1.0.3 Renamed Title "Analyze Inter-Layer Structure of Multilayer Ecological Network" to "Analyze Interconnection Structure of Multilayer Ecological Network". Renamed {Midlayer_role()} to {motif_role()}. We add new definitions of motifs within multilayer networks ({motif_count()} & {motif_role()}). And see vignettes for details. Modify the description of some functions for better understanding. Unpublished!!! Changes in version 2024-4-7 Version: ILSM 1.0.2 For the functions: {motif_count()}; {Midlayer_role()}; {subnet_cor()}; {Hc()}; {Psc()}; {Prc()}; {Node_versatility()}; {igraph_from_matrices()}. We have modified the inputting requirements for matrix data and the handling of data when the function inputting data type is matrix. Changes in version 2024-3-31 Version: ILSM 1.0.1 First release on CRAN Changes in version 1.0.0 First stable design
