splitting character vectors into multiple vectors using strsplit
..."b2" I was wondering whether there is already a function which can extract the "a" and "b" parts of the list splitlist; that is, that can return the same vectors as those created by c("a1","a2") and c("b1","b2"). Thanks, David Romano

XEN and vcpus
...of vcpus to a DomU, Are they dedicated to that VM? For example: If I have 16 vcpus available and 8 DomUs, should I assign 2 vcpus for each one? or could I assign more vcpus (i.e. 6) and the hypervisor takes care of it?

[BUG?] sftp is echoing back prompt and commands in batch mode
...ward compatible with all scripts using batch mode is to allow for a special prefix character to commands to avoid any echoing, just like the "-" is used to avoid a single failing command to terminate the client. Something like "@" or "#" would be ok IMHO. -- Vincenzo Romano - NotOrAnd.IT Information Technologies -- NON QVIETIS MARIBVS NAVTA PERITVS

using 'apply' to apply princomp to an array of datasets
...g answered question 1), now suppose there may be datasets containing NA value -- how could I select the subset of values from dimension 2 corresponding to the datasets for which this is true (again using *apply?)?

using ifelse to remove NA's from specific columns of a data frame containing strings and numbers
...h case it seems I'll have to use another approach entirely, but even if is not the case and lists are acceptable, I'm not sure how to convert a mixed-mode data frame into a vector-like list of elements (which I would hope would work).

different behavior of $ with string literal vs string variable as argument
Hi everyone, I ran into the issue below while trying to execute a command of the form apply(list.names,1, function(x) F(favorite.list$x) ) where list.names is a character vector containing the names of the elements of favorite.list and F is some function defined on a list element. Namely, the $ operator doesn't treat the string variable 'x' as the string it represents, so that,

question about reproducibility/consistency of principal component and lda directions in R
..."singular" in some vague sense I'm not sure how to make precise.) My second attempt was to do the same, but with the first lda scores, so I have the same questions about lda directions, too.

how to "multiply" list of matrices by list of vectors
Hi everyone, I'd like to be able to apply lda to each 2D matrix slice of a 3D array, and then use the scalings to obtain the corresponding lda scores. I can use 'apply' to get a list of the lda output for each 2D slice, and can create a list of the resulting scalings, but I'm not sure how to multiply them in a vectorized way. Here's how I made a list of 2D matrices

writing variables
Can anyone give me insight into upsrw? I have a cyberpower PR2200 UPS (running an experimental version of the powerpanel driver hot off the presses by Arjen (thanks Arjen!!)).

how to parallelize 'apply' across multiple cores on a Mac
Hi everyone, I'm trying to use apply (with a call to zoo's rollapply within) on the columns of a 1.5Kx165K matrix, and I'd like to make use of the other cores on my machine to speed it up. (And hopefully also leave more memory free: I find that after I create a big object like this, I have to save my workspace and then close and reopen R to be able to recover memory tied up by R, but

Samba PDC and Ubuntu desktop client logon script
