upsdrv_info structure
Arnaud, If memory serves, you're the one that 'invented' the upsdrv_info_t subdriver description structure. We seem to have an issue with this on Solaris. I suspect that we're introducing GCC specific behavior here. Technically the typedef here isn't possible in C89, since this suggests that sizeof(upsdrv_info_t) can be determined. This obvious is not the case, since

Simulation Questions
I have the following script for generating a dataset. It works like a champ except for a couple of things. 1. I need the variables "itbs" and "map" to be negatively correlated with the binomial variable "lunch" (around -0.21 and -0.24, respectively). The binomial variable "lunch" needs to remain unchanged. 2. While my generated variables do come out

Error: cannot allocate vector of size x Gb (64-bit ... yet again)
Hello, I am facing the dreaded "Error: cannot allocate vector of size x Gb" and don't understand enough about R (or operating system) memory management to diagnose and solve the problem -- despite studying previous posts and relevant R help -- e.g.: "Error messages beginning cannot allocate vector of size indicate a failure to obtain memory, either because the size exceeded

Fax relaying with T.38
Hi, We've got endpoints and gateways who have T.38 fax support. We now use SER and Asterisk to do our routing and other functionality, but fax doesn't seem to work. Asterisk complains like this: Sep 9 09:25:45 WARNING[467828746]: RTP Read too short Sep 9 09:25:45 WARNING[467828746]: Asked to transmit frame type 256, while native formats is 32 (read/write = 256/256) With lots of the

Explain AGI and AMI
Hi, Can anyone explain the difference between Asterisk Gateway Interface and Asterisk Management Interface ? Is it correct to consider AGI scope to focus on call handling and AMI scope to anything which can be done with Asterisk froma loading new modules to originating calls ?

RODBC package -- sqlQuery(channel,.....,nullstring=0) still gives NA's
R-help, I'm using the RODBC package to retrieve data froma ODBC database which contain NA's.

Out of disk space at 2 GB?
On an ext3 filesystem, what would cause the system to claim it is out of disk space for a program writing information to disk, when df -h shows ample GB available and the file is being written to local disk rather than an nfs-mounted filesystem? I believe the hard drive is good. Ideas welcome. Thanks. Scott

Traffic Shaping
Dear List, I am wanting to perform some traffic shaping as the subject of this email suggests. What I am wanting to do is this; I would like to have traffic shaping performed on the following protocols: HTTP, RDP, GRE, PPTP, SIP and IAX. Obviously I would like to have highest priority set for voice packets so much so that the general http traffic does not impede on the voice packets. I

array elements incorrect
Hello everyone, I have a question as to what code should be used if one wanted to subset from a dataframe of 7000rows by 38 columns.For example if you wanted to generate a array of 100 by 38 would you not use the following: Z<-(dat,dim=c(100,38)) where dat is the dataframe of 7000by 38 Whenever I do this and type show(Z) I get a output of 100 by 38 they all say "integer,7000" as

Matrix indexing in a loop
How do you specify matrix location a[i,j] (or a[i-1,j], etc.) in a "for" loop? I am looking for a flexible method of indexing neighbors over a series of lags (1,2,3...) and I may wish to extend this method to 3D arrays. Example: Data matrix > fun [,1] [,2] [,3] [1,] 1 5 9 [2,] 2 6 10 [3,] 3 7 11 [4,] 4 8 12 For each element a[i,j] in

RODBC package -- sqlQuery(channel,.....,nullstring=0) stillgives NA's
There is something strange in R behaviour (perhaps). I have run the same select in Oracle SQL*Plus (version 10.1.0.2.0) and the output comes out with NULLs (which is what it ougth to be). But in R I still get the same result with NAs (no matter I use na.strings or nullstring arguments) An output example follows below: Using na.string="0" and nullstring="0" (sorry by the

Re: Difference between ZFS and UFS with one LUN froma SAN
This may not be the answer you''re looking for, but I don''t know if it''s something you''ve thought of. If you''re pulling a LUN from an expensive array, with multiple HBA''s in the system, why not run mpxio? If you ARE running mpxio, there shouldn''t be an issue with a path dropping.

Coercing elements of a matrix from integer to double
Ive been converting elements of matrices and arrays, e.g., from Integers to double-precision, by vectorizing the matrix and then remaking it. Alternatively, I can redefine one element as double which then redefines them all. Both methods are quick, so I guess I shouldn't complain, but I would have thought there'd be something more obvious. Have I missed it? Here's my redimensioning

Bug on qr.coef when qr is created by a zero matrix with colnames and all y equals zero
Dear maintainers, I'm reporting a bug in qr.coef that mishandles the colnames of matrix. A minimal reproducible example is as follows: x <- cbind(rep(0, 10), rep(0, 10)) y <- rep(0, 10) q <- qr.default(x) qr.coef(q, y) [1] NA NA If x has colnames, then qr.coef will end up with an error: x <- cbind(x1 = rep(0, 10), x2 = rep(0, 10)) y <- rep(0, 10) q <- qr.default(x)
