  -- 1. Error: (unknown) (@test-test_ezcox.R#30)  --------------------------------
  Failed to launch and connect to R worker on local machine 'localhost' from local machine 'CRANWIN'.
   * The error produced by socketConnection() was: 'reached elapsed time limit' (which suggests that the connection timeout of 120 seconds (argument 'connectTimeout') kicked in)
   * The localhost socket connection that failed to connect to the R worker used port 11567 using a communication timeout of 2592000 seconds and a connection timeout of 120 seconds.
   * Worker launch call: "D:/RCompile/recent/R/bin/x64/Rscript" --default-packages=datasets,utils,grDevices,graphics,stats,methods -e "try(suppressWarnings(cat(Sys.getpid(),file=\"D:/temp/RtmpMNHvaz/future.parent=200724.310145f23193a.pid\")), silent = TRUE)" -e "parallel:::.slaveRSOCK()" MASTER=localhost PORT=11567 OUT=/dev/null TIMEOUT=2592000 XDR=TRUE.
   * Worker (PID 91220) was successfully killed: TRUE
   * Troubleshooting suggestions:
     - Suggestion #1: Set 'verbose=TRUE' to see more details.
     - Suggestion #2: On Windows, output from worker when using 'outfile=NULL' is only visible when running R from a terminal (not a GUI).
