rle(as.numeric(diff(mydf$data_POSIX))) should get you started, I think?

Dear R users,
I have a data frame with a single column of POSIXct elements, like
mydf <- data.frame(data_POSIX=as.POSIXct(c("2012-02-05", "2012-02-06", "2012-02-07", "2012-02-13",
"2012-02-21"), format = "%Y-%m-%d", tz="Etc/GMT-1"))
I need to transform it in a two-columns data frame where I can get rid of
consecutive dates. It should appear like
data_POSIX_init data_POSIX_fin
2012-02-05 2012-02-07
2012-02-13 NA
2012-02-21 NA
I started with two "while cycles" and so on, but this is not an efficient way
to do it.
Could you please give me an hint on how to proceed?
Thank you for your precious attention and help
Stefano
