You can use the 'ts' function.

Example

df <- ts(your_data_frame,
           start=c(1990,1), #The initial date of your data
           end=c(2000,12), #The final date of your data or
           frequency=12)#The frequency of your data, so you don't need of
the 'end' argument

See ?ts and ?as.ts for more.
