setTimeLimit

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 repo
