Contatenating data frames with partial overlap in variable names
Greetings to all. I need to concatenate data frames that do not have all the same variable names, there is only a partial overlap in the variables. So, for example, if i have two data frames, a and b, that look like the following: > a a b 1 1 4 2 2 5 3 3 6 4 4 7 5 5 8 > b c a 1 1 10 2 2 11 3 3 12 4 4 13 5 5 14 i want to concatenate them by row, without any matching, so that the

Multiple checkboxes
Please could someone suggest what might be wrong here. In my view I''m displaying a series of check boxes and when the form is submitted I want the controller to iterate over the values and contatenate them all into a string "1" if the box was checked and "0" if it wasn''t.

New to rails - scaffold command , how to get related items?
Ahoy, I was able to follow the tutorials and build a simple to-do list program with Items and Categories and have the related tables link up w/ the default "scaffold :Items" command plus custom defenitions.

Concatenating of OGG Vorbis files (again)
Hi there, I am trying to find a solution for the problem of contatenating OGG Vorbis files. Yes, I know that this can be done by standard "cat" tool but in this case there are generaly two problems. At first some of the players doesn't seek correctly (e.g. amarok). And the second problem is that if I have many files to concatenate (~50) then it takes quite...

[PATCH] Improve support for exporting btrfs subvolumes.
If you export two subvolumes of a btrfs filesystem, they will both be given the same uuid so lookups will be confused. blkid cannot differentiate the two, so we must use the fsid from statfs64 to identify the filesystem. We cannot tell if blkid or statfs is best without knowing internal details of the filesystem in question, so we need to encode specific knowledge of btrfs in mountd. This is

Concatenating variables
Hi all: I'm having difficulty with something I believe is very simple, but I'm stuck. I have a large data frame that took days to clean and prepare. All I now need to do is concatenate three variables into a single column. For example, I have tenn$up, tenn$down, and tenn$stable which all have values of 1 or 0. I simply want to put all three columns together to create a pattern (e.g.,

simple repeated measures model: dumb user baffled!
I am in the process of transferring from an old version of S+ to using R having used a variety of other packages in the past. I'm hugely impressed with R but it has an excellent but depressing habit of exposing that I'm not a professional statistician and has done so again. Someone has run a nice little repeated measures design on my advice, students randomised to four orders of a
