Offers an interactive 'RStudio' gadget interface for communicating 
    with 'OpenAI' large language models (e.g., 'gpt-5', 'gpt-5-mini', 'gpt-5-nano') 
    (<https://platform.openai.com/docs/api-reference>). 
    Enables users to conduct multiple chat conversations simultaneously in 
    separate tabs. Supports uploading local files (R, PDF, DOCX) to provide 
    context for the models. Allows per-conversation configuration of system 
    messages (where supported by the model). API interactions via the 'httr' 
    package are performed asynchronously using 'promises' and 'future' to avoid 
    blocking the R console. Useful for tasks like code generation, text 
    summarization, and document analysis directly within the 'RStudio' environment. 
    Requires an 'OpenAI' API key set as an environment variable.

Various useful functions for statisticians: describe data, plot Kaplan-Meier curves with numbers of subjects at risk, compare data sets, display spaghetti-plot, build multi-contingency tables...

Several functions are provided to implement a MBPLSDA : components search, optimal model components number search, optimal model validity test by permutation tests, observed values evaluation of optimal model parameters and predicted categories, bootstrap values evaluation of optimal model parameters and predicted cross-validated categories. The use of this package is described in Brandolini-Bunlon et al (2019. Multi-block PLS discriminant analysis for the joint analysis of metabolomic and epidemiological data. Metabolomics, 15(10):134).

Manage the R packages your project depends on in an isolated,
    portable, and reproducible way.

Tools to more conveniently perform tasks associated with
        add-on packages. pacman conveniently wraps library and package
        related functions and names them in an intuitive and consistent
        fashion.  It seeks to combine functionality from lower level
        functions which can speed up workflow.
