Table partitioning in SQL server 2008 R2

Hi,

Is table partitioning feature is not available in SQL 2008 R2? (I am using Enterprise edition)

here is my sql server info:

Microsoft SQL Server Management Studio      10.50.1600.1
Microsoft Analysis Services Client Tools      10.50.1600.1
Microsoft Data Access Components (MDAC)      6.1.7600.16385
Microsoft MSXML      3.0 4.0 5.0 6.0
Microsoft Internet Explorer      8.0.7600.16385
Microsoft .NET Framework      2.0.50727.4963
Operating System      6.1.7600

I am just looking a feature like: right click on table and select partiotion option.. some thing like this.. but i could not find any of these options in SQL 2008 R2. Am I missing some thing? please guide me.
