[R] Resampling 1 time series at another set of (known) irregularly spaced times

[John Hillier]

Dear All,


I would appreciate a quick pointer in the right direction (e.g. www page I could look at, or indicator of which function within a package).


The problem: I have a regular time series of values x at times t (i.e. t, x). I would like to sample them at irregular, known times - this is a second time series (T).


I can move these data between formats as required (i.e. file, vector, matrix, ts etc ....)


I have been searching around for a while and found many packages to regularise time-series (e.g. xts, lubricate, ..... ), but not the reverse as I want to.


Before you ask, I know it might seem a bit odd, but it is necessary for the particular question I'm asking.


Thank you for your time,


John
