Install the "chron" package. Then convert the seconds into days...
Also have a look at the help file for chron().
Below is an example.
Cheers,

library(chron)
epoch <- c(month=3,day=23,year=1935)
data.seconds <- 1046315697+(0:10)*60*60*24
data.days <- data.seconds/(60*60*24)

I have a data file where each entry is indexed by the time in seconds since
epoch (e.g. 1046315697). Is there an easy way to convert this time value into
a more friendly time (such as Month-Year) when plotting it?
I searched through the manual, mailing lists, and functions like as.POSIXct
and s
What about 'plot(1:4, type="s")'?
Is this what you want?

Hi all,
the option type="h" in plot() makes nice vertical (histogram-like) lines. Is there a
way to make similar, horizontal lines?
I can of course resort to using lines() multiple times, but i was hoping that there is

Use matplot() to plot several plots in the same window.
