The installation of S is run under control of a program, and when there are no difficulties, it runs quickly and without intervention. Of course, that is when everything goes right. There is no known upper bound on the time to install. You should have approximately 40Mb of free disk space before installing the S source code and attempting to compile it. MathSoft recommends 45 MB of storage space for UNIX and 80 MB for Windows.
S runs on a wide range of computers, from powerful personal computers to large mainframes.
S-PLUS is available on a variety of UNIX and Windows computers. Please refer to the table below to see platform, hardware requirements, OS requirements and expected upgrade dates. 48 MB or more swap space recommended.
