##### Set CPU and/or Elapsed Time Limits

Functions to set CPU and/or elapsed time limits for top-level computations or the current session.

Keywords
utilities
##### Usage
setTimeLimit(cpu = Inf, elapsed = Inf, transient = FALSE)setSessionTimeLimit(cpu = Inf, elapsed = Inf)
##### Arguments
cpu, elapsed

double (of length one). Set a limit on the total or elapsed cpu time in seconds, respectively.

transient

logical. If TRUE, the limits apply only to the rest of the current computation.

##### Details

setTimeLimit sets limits which apply to each top-level computation, that is a command line (including any continuation lines) entered at the console or from a file. If it is called from within a computation the limits apply to the rest of the computation and (unless transient = TRUE) to subsequent top-level computations.

setSessionTimeLimit sets limits for the rest of the session. Once a session limit is reached it is reset to Inf.

Setting any limit has a small overhead -- well under 1% on the systems measured.

Time limits are checked whenever a user interrupt could occur. This will happen frequently in R code and during Sys.sleep, but only at points in compiled C and Fortran code identified by the code author.

‘Total cpu time’ includes that used by child processes where the latter is reported.
