生成R中任何频率的时间序列

Question

I used to generate time-series in R using xts package as

library(xts)
seq <- timeBasedSeq('2015-06-01/2015-06-05 23')
z <- xts(1:length(seq),seq)

After a bit of tweaks, I find it easy to generate data at a default rate of 1 hour or 1 minute or 1 second. Reading the help page of ?timeBasedseq does not clearly mention how to generate data at other frequncies. Say, I want to generate data at 10 minutes rate. Where Should I mention M (minutes) and 10 in the said command to generate 10 minutes data. Option M is mentioned in the help pages.

Answer 1

This isn't currently possible. The "by" value is essentially hard-coded at 1 unit. It should be possible to patch the code so you can specify the "by" component as something like "10M" for 10-minutes, since seq.POSIXct would accept a by = "10 mins" value.

If you want, you can create an issue for this feature request and we can discuss details of what this patch should include.
