Jeremie,

As months have irregular number of dates, one needs to use a function that
accounts for that (date libraries and packages have that, one of the earliest
for R was my RcppBDT package using Boost Date_Time), or be otherwise clever.

Here is a one-liner using the latter approach:

   seq(as.Date("2010-02-01"), length=24, by="1 month") - 1

See this old StackOverflow answer where I used this before:
