[R] Trapping option settings

2012-07-16 Thread David A Vavra
Something has been changing the setting the width option to 1 and not resetting it. It does this intermittently. What I would like to do is trap changing the setting so I can determine where the change is occurring and hopefully fix it. Is there any easy way to do this?

[R] step function stops with subscript out of bounds

I've been having a problem using the step function to evaluate models. I've simplified the code and get the same problem using the dataset Titanic. The relevant code and output is below. The problem disappears (i.e., 'step' runs correctly) if I rerun the code but change the 'loglm' call to

[R] Effeciently sum 3d table

2012-04-16 Thread David A Vavra
I have a large number of 3d tables that I wish to sum Is there an efficient way to do this? Or perhaps a function I can call? I tried using do.call(sum,listoftables) but that returns a single value. So far, it seems only a loop will do the job. TIA, DAV

I'm using the levelplot function in the lattice package. I am plotting a grid of cells and I want grid lines drawn between cells. I've spent a lot of time trying different options. I've also looked at panel.levelplot. The border parameter seems to be ignored or it doesn't mean cell border color.

[R] Indexing multi-dimensional table

2011-12-22 Thread David A Vavra
I want to take slices of a multi-dimensional table (or array) without knowing the number of dimensions in advance. As a test I tried using (in this example a 3d table): do.call(`[`, list(tbl, x,NULL,NULL)] where I built the list on the fly. It works great as long as I only want

Re: [R] Indexing multi-dimensional table

2011-12-22 Thread David A Vavra
(This does imply you knew the number of dimensions was 3.) Yes, at run time. It looks as though the Nulls became 0's. So if you wanted to use do.call(`[` then this succeeds: do.call(`[`, list(tbl, x, 1:dim(tbl)[2], 1:dim(tbl)[3]) ) ... As does this using the empty comma approach:

Re: [R] Indexing multi-dimensional table

2011-12-22 Thread David A Vavra
From: William Dunlap [mailto:wdun...@tibco.com] You can build the 2nd argument to do.call with alist() instead. alist() produces a list that you can use c() and subscripting on to add or modify arguments. It is usually better to encapsulate this sort of thing in a function like extract() that
