A simple wrapper around the 'ical.js' library executing 
    'Javascript' code via 'V8' (the 'Javascript' engine driving the 'Chrome' 
    browser and 'Node.js' and accessible via the 'V8' R package). 
    This package enables users to parse 'iCalendar' files ('.ics', '.ifb', 
    '.iCal', '.iFBf') into lists and 'data.frames' to ultimately do statistics
    on events, meetings, schedules, birthdays, and the like.

To implement a general framework to quantitatively infer Community Assembly Mechanisms by Phylogenetic-bin-based null model analysis, abbreviated as 'iCAMP' (Ning et al 2020) <doi:10.1038/s41467-020-18560-z>. It can quantitatively assess the relative importance of different community assembly processes, such as selection, dispersal, and drift, for both communities and each phylogenetic group ('bin'). Each bin usually consists of different taxa from a family or an order. The package also provides functions to implement some other published methods, including neutral taxa percentage (Burns et al 2016) <doi:10.1038/ismej.2015.142> based on neutral theory model and quantifying assembly processes based on entire-community null models ('QPEN', Stegen et al 2013) <doi:10.1038/ismej.2013.93>. It also includes some handy functions, particularly for big datasets, such as phylogenetic and taxonomic null model analysis at both community and bin levels, between-taxa niche difference and phylogenetic distance calculation, phylogenetic signal test within phylogenetic groups, midpoint root of big trees, etc. Version 1.3.x mainly improved the function for 'QPEN' and added function 'icamp.cate()' to summarize 'iCAMP' results for different categories of taxa (e.g. core versus rare taxa).

Analysis and visualization of experimentally elucidated mutational
    signatures -- the kind of analysis and visualization in Boot et al.,
    "In-depth characterization of the cisplatin mutational signature in 
    human cell lines and in esophageal and liver tumors", Genome Research 2018, 
    <doi:10.1101/gr.230219.117> and
    "Characterization of colibactin-associated mutational signature in an 
    Asian oral squamous cell carcinoma and in other mucosal tumor types",
    Genome Research 2020 <doi:10.1101/gr.255620.119>.
    'ICAMS' stands for In-depth Characterization 
    and Analysis of Mutational Signatures. 'ICAMS' has functions to read in 
    variant call files (VCFs) and to collate the corresponding catalogs of 
    mutational spectra and to analyze and plot catalogs of mutational spectra
    and signatures. Handles both "counts-based" and "density-based" (i.e.
    representation as mutations per megabase) mutational spectra or signatures.
