to extract data

Hi R-users,

I have a set of data from 1958-2009, how do I extract the data from 1927 and 2007?
 
beechworth.dt
     Year Month  Rain
1    1858     3  21.8
2    1858     4  47.0
3    1858     5  70.1
4    1858     6  78.7
5    1858     7 101.6
6    1858     8 129.8
7    1858     9  80.8
8    1858    10  41.9
 ...
 
     2009    ......
 
 
I tried:
 
 beechworth.dt.2 <- beechworth.dt[beechworth.dt$Year=="1927":"2007",]

 
and got
 
Warning message:
In beechworth.dt$Year == "1927":"2007" :
  longer object length is not a multiple of shorter object length
 
Thank you so much for any help given.
