Dropping dates except specific year from panel data

Question

I have panel data from 2000 to 2017. I want to select rows which are 2005.

Amazingly

mydata <- subset(mydata, select= c(mydata$Year>="2005"))

did not work. Any suggestion?

I like the data.table solution: `library(data.table) as.data.table(df)[year>=2005]` Only 2005 `library(data.table) as.data.table(df)[year==2005]` — LocoGris, Jan 24 '19 at 12:40

It is assumed the data is in date or numeric format.

   library(dplyr)
    df%>% 
      filter(year>=2005)

Only 2005:

library(dplyr)
flights %>% 
  filter(year==2005)

No problem, here is the list of [canonical Q&As for R](https://github.com/r-public/HammeR/blob/master/Canonicals.md), I use them to suggest a link in the comments if I think the post is a duplicate. e.g.: "Possible duplicate [link]" – zx8754 Jan 24 '19 at 12:51
