Foolish? Try convenient. Can't win for losing today. Anyway, I most
certainly did not make the mistake you suggest, though some other mistake is
possible. I never said it printed nothing; I was very explicit that it
described it as a data frame with the correct number of rows and columns; it
simply would not print the data.
I didn't mean to be critical. I'm just trying to understand
how you managed to get to the stage where R will show you
that 'data' "is a data frame with specific (correct) number of
rows and columns, but won't show me what remains in the frame".
This should be reproducible. Who knows, you may have found a
bug that should be fixed. So what was the precise message from
R when it told you that it had the dataframe but wouldn't
print it. Can you make up a reproducible example?

Josh, Jim,
Thanks for responding. So far, it looks like my use of the name data was the
problem - that could have taken some time to find. I typically do not attach
frames (and did not here), so I end up with lots of this$that in my code.
While I think it's foolish to call your data.frame 'data', I really doubt that
that's the cause of your troubles. More likely you did something else
afterwards that caused your data to be 'unprintable'. Or perhaps you goofed up
the subsetting with something like
data = data(-3,);
But I would have expected R to print _some_ thing, if only an error message.
Anyway, I'm glad the problem is resolved (for now).

If it gives me any more trouble, I will indeed post an example.
Thanks!
Bill

Hi Bill,
Several things come to mind. First, try naming your data frame something
besides a function name (data() is also a function).
Second, have you attached the data frame?
Using: data = data[-3, ] worked fine for me when I made up some data.
Perhaps you can create a minimal and reproducible example?
You might also send us the results of:
sessionInfo()
ls()
search()
Cheers,
Josh

Hello all,
I am loading a data frame, fitting a model, getting diagnostic plots and they
are flagging a couple of observations as problematic. Fair enough, and I want
re-fit without them.
After I delete an offending row (identified by one of the diagnostic
plots), something like
data = data[-3,];
then R will no longer print the contents of the data frame; it tells me it is a
data frame with specific (correct) number of rows and columns, but won't show
me what remains in the frame like it does before the deletion. Is there a way
to get around that, either using a different deletion technique or another
function? print(data) and show(data) are not helping.
Ultimately, I am trying to go through a couple of iterations of find
pathologic points, delete and re-fit. In this case I could guess at what is
wrong and probably be correct, but I want to follow the clues as a learning
exercise. Once that is complete, I plan to plot everything with the deleted
points emphasized.
Bill
