Hello, I'm trying to do cor(x1,x2) and I get the following error: Error in cor.default(x1, x2) : missing observations in cov/cor A few things: 1. I've used cor() many times and have never encountered this error. 2. length(x1) = length(x2) 3. is.numeric(x1) = is.numeric(x2) = TRUE 4. which(is.na(x1)) = which(is.na(x2)) = integer(0) {the same goes for is.nan()} 5. I also try

Hi All, I have a vector of data on which I am operating. The equation with which I want to operate on the vector has a value k. I want to run the equation and output a new vector, each time replacing k with each value from the sequence I defined. I have thought about using for loops and such, but this seems like overkill. I am wondering if there is a simple solution that would allow me to

Hello, This code works fine but is so fast I can't see anything but the last plot. for (i in nrow(X)){ plot(as.numeric(d[i,])) } I'd like to view a plot every 500 milliseconds, nrow(X) = 400. How?

We recently upgraded our NT4 Domain to Win2k. We use Samba 2.0.7 running on Solaris 2.6 servers. We are getting buffer overuns in the log files when running 'domain_client_validate' which appears to be due to extensive group membership (SID History is not being used). Are there any patches/fixes available to get round this problem? Thankyou in anticipation. Regards, Rich Sprigg

...ay to only forward specific identities to some hosts. What I would really like to have is a way to only forward the identity that gave me a successful auth: % ls ~/.ssh | grep .pub id_ecdsa.pub id_ed25519.pub id_rsa.pub % cat .ssh/config Host example.com: IdentitiesOnly=yes IdentityFile=/home/tspriggs/.ssh/id_rsa.pub Host another-example.com: IdentitiesOnly=yes IdentityFile=/home/tspriggs/.ssh/id_ecdsa.pub # This would be super cool: Host * OnlyForwardAuthedKey=yes % ssh tspriggs at example.com example.com % ssh-agent -L ssh-rsa ... example.com % ssh tspriggs at another-example.com Perm...

I would like to create a new dataframe from the DateTime column of an existing dataframe and a numeric vector. When I do cbind(x[,1], y) the result is: [1,] 1199370600 12.500 [2,] 1199371200 69.375 [3,] 1199371800 23.750 where the first column you see used to look like: "2008-01-03 08:30:00 Central Standard Time" "2008-01-03 08:40:00 Central Standard Time"

I thnk what you want is ?outer. e.g.: outer(Data -min(Data),value,FUN = "+") Whether this works for your real task, however, may depend on details and complexities that you have omitted.

Regarding "financial" data: I have a high frequency (1 minute) measure of supply/demand and I'd like to know if it has any influence on short term price changes (also 1 minute). Question: How do I calculate the correlation between this supply/demand measure and price changes (correctly)? Some facts about that data: The price changes and supply/demand measure are non-normal. An

It depends a bit on what you plan to do with the results. A loop would be easy and straightforward: > k <- 1:5 > for(k in 1:5) print(Data - min(Data) + k) [1] 1 2 3 4 5 6 7 8 9 10 [1] 2 3 4 5 6 7 8 9 10 11 [1] 3 4 5 6 7 8 9 10 11 12 [1] 4 5 6 7 8 9 10 11 12 13 [1] 5 6 7 8 9 10 11 12 13 14 Or you can use sapply() to hide the loop: > sapply(1:5,

We are looking for a replacement enterprise file system to handle storage needs for our campus. For the past 10 years, we have been happily using DFS (the distributed file system component of DCE), but unfortunately IBM killed off that product and we have been running without support for over a year now. We have looked at a variety of possible options, none of which have proven fruitful. We are

I suspect it''s probably not a good idea but I was wondering if someone could clarify the details. I have 4 250G SATA(150) disks and 1 250G PATA(133) disk. Would it cause problems if I created a raidz1 pool across all 5 drives? I know the PATA drive is slower so would it slow the access across the whole pool or just when accessing that disk? Thanks for your input. - Chris

Hi. I''d like to request a feature be added to zfs. Currently, on SAN attached disk, zpool shows up with a big WWN for the disk. If ZFS (or the zpool command, in particular) had a text field for arbitrary information, it would be possible to add something that would indicate what LUN on what array the disk in question might be. This would make troubleshooting and general

We are using MySQL, and love the idea of using zfs for this. We are used to using Direct I/O to bypass file system caching (let the DB do this). Does this exist for zfs? This message posted from opensolaris.org

I have a data.frame object and I don't really understand how to made an xts class out of it. Consider: > x <- data.frame(datetime, ltp, ltv) > head(x, 2) datetime ltp ltv 1 2009-05-05 07:30:01.604 899 1 2 2009-05-05 07:30:01.963 899 15 > class(x$datetime) [1] "POSIXt" "POSIXct" #This works for only one column and why do I lose the name
