These functions were developed within SECFISH project (Strengthening regional cooperation in the area of fisheries  data collection-Socio-economic data collection for fisheries, aquaculture and the processing industry at EU level). They are aimed at identifying  correlations between costs and transversal variables by metier using individual vessel data and for disaggregating variable costs from  fleet segment to metier  level.

Estimating parameters of site clusters on 2D & 3D square lattice with various lattice sizes, relative fractions of open sites (occupation probability), iso- & anisotropy, von Neumann & Moore (1,d)-neighborhoods, described by Moskalev P.V. et al. (2011) <arXiv:1105.2334v1>.

Functions to estimate the density and size of a spatially 
  distributed animal population sampled with an array of passive detectors, 
  such as traps, or by searching polygons or transects. Models incorporating 
  distance-dependent detection are fitted by maximizing the likelihood. 
  Tools are included for data manipulation and model selection.

Tools for designing spatially explicit capture-recapture studies of animal populations. This is primarily a simulation manager for package 'secr'. Extensions in version 2.5.0 include costing and evaluation of detector spacing.

Allow sharing sensitive information, for example passwords,
    'API' keys, etc., in R packages, using public key cryptography.

Fast and memory-efficient streaming hash functions,
    binary/text encoding and serialization. Hashes strings and raw vectors
    directly.  Stream hashes files which can be larger than memory, as
    well as in-memory objects through R's serialization mechanism.
    Implements the SHA-256, SHA-3 and 'Keccak' cryptographic hash
    functions, SHAKE256 extendable-output function (XOF), 'SipHash'
    pseudo-random function, base64 (including the URL-safe variant) and
    base58 encoding, 'CBOR' and 'JSON' serialization.

Facilitates secret management by storing credentials in a dedicated file, 
          keeping them out of your code base. 
          The secrets are stored without encryption.  
          This package is compatible with secrets stored by the 'SecretsProvider' 'Python' package <https://pypi.org/project/SecretsProvider/>.
