From the document it is apparent to me that I need as.POSIXct  (I have

a double representing the number of millis since 1/1/1970 and I need
to construct a datetime object). I see it showing how to construct the
time object from a string representing the time but now fro a double
of millis. Does anyone know hoe to do that?

If by millis you mean milliseconds (i.e. one thousandths of a second)
then POSIXct does not support that resolution, but if rounding to 
seconds is ok then 

  structure(round(x/1000), class = c("POSIXt", "POSIXct"))

should give it to you assuming x is the number of milliseconds.
