How to make an empty vector of POSIXct

Question

I want to make an empty vector of POSIXct so that I can put a POSIXct in it:

vec <- vector(\"POSIXct\", 10)
vec
vec[1] <- \"2014-         


        

Answer 1

I usually initialize things to NA:

as.POSIXct(rep(NA, 10))

works well in this case. It's explicitly doing what happens under-the-hood in @RichardScriven's answer---see the comments there for a longer discussion.
