VMSbase is an R suite for the analysis of vessel monitoring system (VMS) and logbook data, which constitute two of the primary sources of information for spatially explicit models of the fishing effort. It is conceived to solve many of the nuisance details related to this specific kind of data, providing a straightforward path from data massaging and management to sophisticated analyses and outputs.


VMSbase package gives you the tools you need to process, analyze and plot your VMS and Logbook data. With VMSbase you can easily visualize data in different ways, discover geographic patterns, and convey that information in a straightforward manner. VMSbase provides everything you need to extract information from VMS data with a single, easy-to-use package which combines the potentiality of R with a user-friendly graphical interface.

VMS (Virtual Memory System) is a base for operation systems which was developed by Digital Equipment Corporation (DEC) in the late 1970s. It is a multiuser, multitasking operating system for minicomputers. It is used for running various applications like databases, network services, scientific applications, and office automation tools. The core of VMS is the executive, which is responsible for the scheduling of jobs and the allocation of resources. It also manages the virtual memory system, which is the main feature of VMS. This allows multiple programs to run simultaneously in a secure environment, as each program is given its own memory area which is isolated from the other programs.


VMS also provides support for distributed processing and distributed databases. It allows programs to be run on different computers on a network and can access data stored on other computers. This is useful for running applications that require access to large amounts of data, or for running applications across multiple computers. VMS also provides strong security measures such as encryption, user authentication, and access control. It also offers high availability and scalability, as it can be extended to support additional users and applications.

VMS (Virtual Memory System) is a computer operating system created by Digital Equipment Corporation (DEC) for its family of VAX computers. It was first released in 1977 and was one of the first commercial operating systems to be based on virtual memory. VMS is a multiuser, multitasking, timesharing operating system. It is designed to support a variety of hardware architectures, including VAX, Alpha, and Itanium. VMS is a proprietary operating system, meaning that it is owned and developed by DEC. VMS has been praised for its reliability, scalability, and security. It supports a wide variety of languages, including Pascal, C, Fortran, ALGOL, BASIC, and COBOL. Its multitasking capabilities allow multiple programs to be run simultaneously. Additionally, it has builtin support for networking protocols such as DECnet and TCP/IP.


One of the key features of VMS is its support for virtual memory. Virtual memory allows the system to use more memory than is physically present in the system by using a combination of RAM and disk storage. This allows programs to run faster and more efficiently, and it also allows multiple programs to access the same memory without interfering with each other. VMS is used in a variety of industries, including aerospace, government, healthcare, and banking. It has also been used to develop software for embedded systems, such as those found in automobiles, mobile phones, and PDAs. VMS is a powerful and reliable operating system that is used in a wide variety of applications. Its virtual memory capabilities make it a great choice for applications that require high performance. Additionally, its robust security features make it an excellent choice for applications that need to be secure.
