Hi,

I am calling a function with different arguments to read different  
files and

want the results to be stored in
different matrices.

Ex:
cData1 = NULL
cData2 = NULL

readData = function(cData, start, end)
{


  cData = //reads from the file
}

I am calling the functions using
readData(cData1,1,3)
readData(cData2,4,7)

But After running the code, cData1 and cData2 are not getting updated.
Is there a way in R to do this?
You need to assign the results of the function to an R object in the  
global environment. At the moment calling readData() only creates the  
cData object in the environment of the function which then disappears  
after function completion.


Try :

cdata_1_1_3 - readData(cData1,1,3)
cdata_2_4_7 - readData(cData2,4,7)

 Hi,

 I tried this approach.
 cdata_1_1_3 - readData(cData1,1,3)
 cdata_2_4_7 - readData(cData2,4,7)

 Its still not working. The result I get is NULL.

Then the function (which you have not provided) is faulty, but there  
is not way we can debug a function we cannot see.
