[R] Matrix Indexing

[Kim Fai Wong]

Hi,

I have the following problem.
In a csv file I have under column A, the date, and column B, the prices.
Thus, for example, the file looks something like this ->

1/31/04      2.5
2/1/04        2.6
...
4/12/04       3.5

Basically,  I use the function inputframe = read.csv( )
which reads the csv file into the inputframe.

My question is, how can I make a function that has, as inputs, start_date 
and end_date,
so that the inputframe would not return all of these prices but only the 
ones during the
period I input?

For example, if I input 3/1/04 and 3/11/04, the inputframe only contains the 
prices for
this period.

Any help is appreciated!!
