Hello, I have an old crossword program that runs OK on Win98, WinMe, and XP. I have installed, via yum, wine and wine-devel and the associated dependencies on my Fedora 8 system. I have copied all the files from the program's install floppy to a directory in my home folder, the same as installing it on XP. However, when the program tries to access the word files it fails and says to see

Hi everyone, When the CCF between two series of observations is plotted in R, a line indicating (presumably) the significance threshold appears across the plot. Does anyone know how this threshold is determined (it is different for each set of series) and how its value can be extracted from R? I've tried saving the CCF into an object and unclassing the object, but there's nothing there to

Hello, I have a question about the constant folding for fdiv instructions. For the instruction "fdiv double 0.0, 0.0", the folded result is inf. I think this should be nan. Can anyone tell me why it is not nan? Thanks. Leo _________________________________________________________________ Exercise your brain! Try Flexicon.

i have a customer that needs to plug the phones into the pc's using the pass-through rj45 available on most sip phones the question they are asking me is how to keep the data network separate from / secure from the voip network i understand they can set up vlans but i am hazy on a few details 1 since the phones are plugged into the pc's how will the phones be segmented into their own

Hi, I made the mistake of doing an rsync of a directory into the wrong destination, so that the destination became a mix of two directories of unrelated files. Top unravel the mess, I could need something like a --delete-existing option. The semantics would be to delete at the destination ONLY those files that exists at the source. I tried to concoct a combination of options that would do

Since 2008, Microsoft (formerly Revolution Analytics) staff and guests have written about R every weekday at the Revolutions blog (http://blog.revolutionanalytics.com) and every month I post a summary of articles from the previous month of particular interest to readers of r-help. In case you missed them, here are some articles related to R from the month of October: A recent survey of

I recently came across a post (circa jan-feb 2008) where a user had encountered a fatal and unrecoverable crash when starting Photoshop for the second or subsequent time. I've noticed that this issue has happened to many people, myself included while installing it on someone's system today, and that, while there is a short-term workaround (noted below), nobody has yet posted an actual

Dear all, I'm wondering if there exist vectorized forms of 'isTRUE()', 'identical()' and 'all.equal()'. My problem is that I wish to test if each element of a vector is equal to a particular value (or numerically close), whilst dealing carefully with NAs and so on. However, using sapply() with identical() is very slow because it makes so many separate function calls:

The code works faster with <4 x float> types, with still works a bit slower than the scalar

Hi Sebastian, Thanks for looking at this. I don't think that printing to stdout is the right thing to do. I think that we need to go through the clang driver.

I'm not sure I understand exactly what you are suggesting: could you please give some more details? Do you mean that we should use clang's diagnostic infrastructure to report these messages?

I want to produce some boxplots (and qqnorm plots) for each of a series of groups. It is easy to produce the boxplots or qqplots by groups using either by() or tapply(), but the moment that I want unique labels for each boxplot, I seem to be stuck using a for loop to achieve the effect. For example: tapply(fstat$femur, fstat$race, boxplot) by(fstat$femur, fstat$race, boxplot) gives nicely

Dear R users, I want to apply a function that takes two vectors as input to all pairs (combinations (nrow(X), 2))of matrix rows in a matrix. I know that ideally, one should avoid loops in R, but after reading the docs for do.call, apply, etc, I still don't know how to write the nested loop in a vectorized way. Example data: x = matrix(rnorm(1000), 100, 100) zeros = runif(90) x[] # this is
