Hi Everyone, To complete the outer() and kronecker() functions in the base, may I suggest the following tensor() function, which allows the multiplication of arrays through sets of conformable dimensions. I am happy to write a help page if required. The code also needs a setdiff() function which prompts me to ask: what about simple set functions? I expect many of us have written our own

Just a minor point, but the adj argument in ?text is described wrongly (0.64.1). Perhaps the following might be added to the details. Values of 0, 0.5, and 1 specify left/top, middle and right/bottom, respectively. The default is for centred text, ie \code{adj = c(0.5, 0.5)}. Cheers, Jonathan.

Hi everyone, I do a lot of work with large variance matrices, and I like to use "crossprod" for speed and to keep everything symmetric, i.e. I often compute "crossprod(Q %*% t(A))" for "A %*% Sigma %*% t(A)", where "Sigma" decomposes as "t(Q) %*% Q". I notice in the code that "crossprod", current definition > crossprod function (x,

I would like to suggest a slight modification to diag(). In the case where x is a matrix with both row names and column names the same, it would be reasonable if the resulting vector also had those names. I often use diag() on variance matrices, where this modification is helpful. The modification requires replacing if (is.matrix(x) && nargs() == 1) return(c(x)[1 +

Hi everyone, Can I suggest an addition to the help page for logical AND and OR, indicating the behaviour of NA (which is currently not mentioned at all). I think something simple like an extra paragraph in Details, eg \code{NA} is a valid logical object. Where a component of \code{x} or \code{y} is \code{NA}, the result will be \code{NA} if the outcome is ambiguous. In other words \code{NA

Might it be possible to tighten the definition of "is.qr". I noticed that after I mistakenly typed example(lm) # make lm object named lm.D9 qr.Q(lm.D9) which exhausted the heap memory and produced two warning messages. As an object of class "lm" has a "qr" component, "is.qr" failed to detect that "lm.D9" was not a "qr" object. The

Is there a version of the pv_ops kernel that will do HVM and work with fc11? I have been failing miserably trying to get it to work. I have followed Boris''s guide at: http://bderzhavets.wordpress.com/2009/06/10/setup-fedora-11-pv-domu-at-xen-3-4-1-dom0-kernel-2-6-30-rc6-tip-on-top-of-fedora-11/ But have had no success so far. I am wanting to know what is the version of the pv_ops

Hi everyone, As "intensities" is deprecated as a synonym for "density" in the output of hist it would be a good idea to replace its occurence with "density" in plot.histogram, where we currently have y <- if (freq) x$counts else x$intensities Note that, to add to the confusion, x$density is also referred to in plot.histogram. Cheers, Jonathan.

In legend() is it possibly to mix lines and boxes? I would like to do something like legend(locator(1), legend = c("al", "ben", "chris", "dave"), lty = c(1, 2, 3, NA), fill = c(NA, NA, NA, "gray")) to indicate that "al", "ben" and "chris" have lines, and "dave" has a gray shading. Many thanks,

...Luke's idmap_ad plugin from PADL, so I built that (for Debian you also need to at least configure a Samba source tree somewhere - I apt-get the source, and killed the build after the configuration). Now, I have winbindd using the idmap-ad plugin, and wbinfo can convert SIDs to UIDs. (wbinfo -n jonr gets the SID, and wbinfo -S <sid> gets the uid).

Hello, I have setup XCP using the install .iso and have been trying to do an install over http, this has failed miserably each time. So now I want to just carve out an lvm from the disk and put my .iso files in there and install off of them. How is this done? I can create an lvm easy enough but I am not sure how to mount it and expose it to XCP. Is there some type of magic I am missing? Is there

I am at the end of my rope, I am trying to get a winxp box to logon to a pdc using freebsd5.1 and keep getting "Logon failure: unknown user name or bad passsword." or "Access Denied". I am trying to logon with 'root' and the user is in smbpasswd and /etc/passwd. I think my problem is I am not sure how to add the machine account into the samba server. I have tried just

Hello List, I am using samba and cups as a print server and have added it into my 2003 AD. What I am would like is to not install any drivers locally on the client but have samba automagically send the correct PPD to the client. I can add my samba server by using the 'net ads join -U Administrator' command and it works as do the commands 'wbinfo' and 'getent

Hello, I am using XCP 1.0 and am accessing it with XenCenter. I have three NIC''s and I have bonded two of them through the XenCenter frontend. I then create a VLAN using XenCenter and attach it to the bond0. I create a VM and create its NIC to use VLAN 10, which it does and when the VM boots the NIC shows Active inside of XenCenter. When I look at the XCP host it shows VLAN 10 as an

Hello, We are having this issue with samba and OSX 10.2.3. We are using freebsd4.7 serving samba as a fileserver for our company, we have a mix of windows and macs connecting to it. The windows machines work just fine the macs are another story. I have narrowed it down to this: I can open a file/document from the fileserver on my mac and edit it but it tells me I dont have the permissions to
