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!!
Kim
