R 2.7.1 (Default branch)
06-23-2008
R is a language and environment for statistical computing and graphics. It is similar to S, which was developed at Bell Laboratories by John Chambers et al. It provides a wide variety of statistical and graphical techniques (linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, etc.). R is designed as a true computer language with control-flow constructions for iteration and alternation, and it allows users to add additional functionality by defining new functions. For computationally intensive tasks, Fortran and C code can be linked and called at run time.License: GNU General Public License (GPL)Changes:|

cachefsstat(1M) cachefsstat(1M) NAME
cachefsstat - Cache File System statistics SYNOPSIS
path... ] DESCRIPTION
The command displays statistical information about the cache filesystem mounted on path. The statistical information includes cache hits and misses, consistency checking, and modification operations. If path is not specified, all mounted cache filesystems are used. can also be used to reinitialize this information (see description for the option). The statistical information has the following format: <cache hit rate> <consistency checks> <modifies> where each of the above is defined as: cache hit rate The percentage of cache hits over the total number of attempts followed by the actual numbers of hits and misses. consistency checks The number of consistency checks performed followed by the number that passed and the number that failed. modifies The number of modify operations, including writes, creates, and so on. Options recognizes the following option: Zero (reinitialize) statistics. Execute before executing again to gather statistics on the cache performance. This option can only be used by the supe- ruser. The statistics printed reflect those just before the statistics are reinitialized. RETURN VALUE
returns the following values: Success. non-zero An error occurred. EXAMPLES
