Ifelse Execution
2 messages · Bhupendrasinh Thakre, Jeff Newmiller
Ifelse is a vector function and is absolutely inappropriate for that use.
Use "if" instead.
Also, read the help for Sys.sleep... you need to tell it how long you want to sleep. You should compute how long that is from now and sleep that long.

Hi Everyone,
I am trying to run a time based query and need some of your help.
Not much of data or packages.
Just a simple one.
Query I am trying to execute.
ifelse ((as.numeric(as.POSIXct("2012-10-01 20:38:00"))),
(rnorm(1,2,1)),(Sys.sleep()))
Note. Why I am using as.numeric is as I have a list of time at which I
wanted to run the command.
Something like
1349142243
1349138667
Question.
1. The query is running before the time reaches in both R-Studio and
R-Terminal in Mac based System.
2. Sys.sleep () is ineffective in putting R on sleep till the time
comes.
