Dear all,
I just found a weird behavior of the timeDate related functions Sys.timeDate()
and as.timeDate().
Both of them take place when showing fractions of seconds and I think they
might have the same source.
Do you know if it should be considered a bug of Sys.timeDate()? Also, what is a
Dear all,
Excuse me for my searching skills: I just couldn't figure out how to do any
simple text to speech in R console.
What I want to do is, out put simple English words or sentences to speaker as
voice. No fanciness. For example, I want the R console to speak Hello world
or Howdy.

Dear all,
Happy new year!
I have a question re using sapply. Below is a dummy example that would
replicate the error I saw.
##Code Starts here
DummyFunc - function(x) {
if (x 0) {
return (x)
} else
{
return (-x)
}
}
Y = data.frame(val = c(-3:7))
sapply(Y, FUN = DummyFunc)
##Code ends here
the behavior. Is there an
*apply function that will fee elements of the input data.frame into FUN
instead of whole columns? Thanks.

Dear all,
I am using the ISOdatetime function like this:
test.info$TradeTime = with(test.info, mapply(FUN = ISOdatetime, Year, Month,
Day, Hour, Minute, 60, EST))
Where Year, Month etc are all numeric.
I think ISOdatetime should return a POSIXct object. However, the result I

Dear all,
I am having a problem with mapply. I guess the reason is that mapply is not
vectorized. But could you please take a look at my code below and help me to
find a solution (either a better way to use mapply or a different function to
call). Thanks a lot!
