R help - Aug 2013 - Double return statement

Dear R forum,

I have a function which generates say two outputs, say output_1 and output_2.
Output_1 is a single row output whereas Output_2 is a dataframe having multiple
records. Is it possible to use two return statements in function. Output_2 uses
some records from output_1, hence I need to have these outputs generated from
the same function. 

Thanking in advance

With warm regards

Hi,

The usual thing to do is return a list containing output_1 and output_2.

Dear Katherine,

Combine both outputs in a list and return that.

return(list(first = output.1, second = output.2))

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.

The combination of some data and an aching desire for an answer does not ensure
that a reasonable answer can be extracted from a given body of data.
