R help - May 2009 - Query regarding na.omit function

Hi friends,
I have a query regarding na.omit function.Please ,someone help me.

I have a function
xyz_function<-function(arguments)
{
       some code
       return(list(matrix=dataset))
}

xyz_function_returnvalue<-xyz_function(passed argumentss)

*Case-I*
xyz_function_returnvalue_deletingNArows<-na.omit((xyz_function_returnvalue))
*Case-II*
 xyz_function_returnvalue_dataframe_deletingNArows<-na.omit(as.data.frame((pair_raw_data$matrix)))

Both case I and II don't work.My dataset has rows with NA values,that's
for
sure.



Whereas this simple code,works fine.I mean from the data frame the rows
containing NA values could be easily deleted.

DF <- data.frame(x = c(1, 2, 3), y = c(0, 10, NA))
DF<-na.omit(DF)
print(DF)

Thanks

PLEASE do read the posting guide
http://www.R-project.org/posting-guide.html<http://www.r-project.org/posting-guide.html>
and provide commented, minimal, self-contained, reproducible code.

We have no idea of the structure of 'dataset' that is being returned by
your
function.  This example works fine for dataframes:
> x <- list(matrix=data.frame(x = c(1, 2, 3), y = c(0, 10, NA)))
> x
$matrix
  x  y
1 1  0
2 2 10
3 3 NA
> na.omit(x$matrix)
  x  y
1 1  0
2 2 10
> na.omit(as.data.frame(x$matrix))
  x  y
1 1  0
2 2 10

You might also look at 'complete.cases', but a real example would be
helpful
in providing information.

Hi Jim,

xyz_function<-function(arguments)
> {
>        some code

pair_raw_data<-changeMissingValuestoNA(pair_raw_data$matrix,pair_raw_data$dim,missing_values)

Type of my dataset was a "list".I tried checking that ,changing my
dataset
to some other types.

Thanks
