Information about the package, root, which is shipped with common Linux distributions. The root package is designed for, Numerical data analysis framework.
Numerical data analysis framework
The ROOT system provides a set of object oriented frameworks with all the functionality needed to handle and analyze large amounts of data in a very efficient way. Having the data defined as a set of objects, specialized storage methods are used to get direct access to the separate attributes of the selected objects, without having to touch the bulk of the data. Included are histogramming methods in 1, 2 and 3 dimensions, curve fitting, function evaluation, minimization, graphics and visualization classes to allow the easy setup of an analysis system that can query and process the data interactively or in batch mode. Thanks to the built in CINT C++ interpreter the command language, the scripting, or macro, language and the programming language are all C++. The interpreter allows for fast prototyping of the macros since it removes the time consuming compile/link cycle. It also provides a good environment to learn C++. If more performance is needed the interactively developed macros can be compiled using a C++ compiler. The system has been designed in such a way that it can query its databases in parallel on MPP machines or on clusters of workstations or high-end PCs. ROOT is an open system that can be dynamically extended by linking external libraries. This makes ROOT a premier platform on which to build data acquisition, simulation and data analysis systems.
Control the root package with the following handy commands outlined below.
yum install root
This command will install root on the server.
yum remove root
This command will un-install root on the server. When you run this command, you will be asked if you are sure that you want to remove root, so you have to manually confirm that you want to do this.
yum -y remove root
This command will un-install root on the server. When you run this command with th e -y flag, you will not be prompted to check that you are sure you want to remove the package - so be sure you absolutely want to remove root when using the -y flag.
yum update root
This command will update root to the latest version. When you run this command, you will be asked if you are sure that you want to remove root, so you have to manually confirm that you want to do this.
yum -y update root
This command will update root to the latest version. When you run this command with the -y flag, you will not be prompted to check that you are sure you want to remove the package - so be sure you absolutely want to remove root when using the -y flag.
yum info root
This command will show you core information about the root package.
yum deplist root
This command will show you the dependencies for root. Thankfully, when using Yum, if dependencies are required, these are also installed at the same time so you don't have to worry too much about that.
yum check-update root
This command will check if there is an update waiting on root. When you run this command this will return nothing if there is nothing to update, or, will return the package name if the package is due to be updated.
