I have a data set for different time intervals. The data has three comment lines before data for each time interval. For each time interval there are 500 data points. I want to change the dataset such that I have the following format: t1 t2 t3 ................ 0.00208 0.00417 0.00625 ................. a1 a2 a3 ...................

Dear Asterisk community, sorry if I'm so stupid, but I couldn't register myself with Asterisk.

Dear R experts. 'D()' function recognizes some of the analitical functions, such as sin, cos, etc. But I'd like to take analytical derivatives from asin, atan etc. functions. Are there any R packages providing that features? Thanks. -- Timur.

I am at my first steps with R... and I already notice that the console has a quite limited number of lines. Can anyone tell me how to visualise all the information, which is actually present? I only see the last part of the output, which obviosly exceeds the maximum number of rows in the console. Thank you very much for your help! Daniela [[alternative HTML version deleted]]

Dear R experts, format(12345678, digits = 2) gives [1] "1.2e+07" while format(1234567, digits = 2) gives [1] "1234567" but I'd like the last number to be represented as "1.2e+06" string too. Where am I wrong? Thanks, Timur.

Dear useRs, it's quite difficult for me to find `Error:'s in my R code, because R does say about error itself, but say nothing about its location, say, string number and file with an error (which may be `source'd from another file). Are there any option for turning of the similar feature, or R can not do such a thing at all? Thanks. -- WBR, Timur.

Hello, dear Asterisk experts. When I run Asterisk (CVS HEAD version), I'm not able to play music anymore -- asterisk seems to capture sound device. Is it not a bug, but a feature? That's unlike stable (1.0.7 and 1.0.9) versions, when I can, say, run an IP telephone on the *same* machine and listen what Asterisk' autoattendant says. Now I can't do that, I need Asterisk and client

Hi Ogg experts! My current work is catenating packets from several ogg files to the one long stream, so I'd like to create stream once, and then reset it just before reading codec headers from every new file. However, after calling ogg_stream_reset_serialno(ogg_stream_state *os, int serialno), bos page is not pushed in stream since it calls ogg_stream_reset(ogg_stream_state *os), which

Dear R experts, I looked at the body of, say, `optim' function and found the call to the `.Internal', C optim function. It looks like this: .Internal(optim(par, fn1, gr1, method, con, lower, upper)) On the other hand, the C prototype of optim is: SEXP do_optim(SEXP call, SEXP op, SEXP args, SEXP rho); So, I guess that all the list of parameters passing in R are assigned to

Dear R help, I run R at home and the work, I have Debian Linux on both machines and the same 'r-base-core' deb packages installed. So I tried to run the same R script, which plots graph in x11 device and then dump it to eps file (x11 and eps you'll find attached). On the home machine there are some stranges in x11 plot as well as in eps file. On the work machine all the ok, despite

Dear R experts! I try to minimize a function with external C fitting function. I get the hessian matrix. Here it is: [,1] [,2] [,3] [,4] [1,] 1.8816631 0 0.8859803 0 [2,] 0.0000000 0 0.0000000 0 [3,] 0.8859803 0 0.4859983 0 [4,] 0.0000000 0 0.0000000 0 Second and fourth rows/columns have zero values only. That's OK, because that ones related

Hello there I tend to e-mail user accounts to my servers with /sbin/nologin and /dev/null as their shell and home directories respectively. I have discovered that Dovcot does not like it when a user does not have a home directory. Obviosly the user POP3 and not IMAP! :P Is there a work around for this? I have a suspicion it is one of the chroot option, but I do not know the meaning chroot.

Dear R experts, I just upgraded R from 1.8.1 to 1.9.0 version. My .First() function in ~/.Rprofile contains x11() and par() functions. .First <- function() { x11(display = "", 8.0, 5.0) par(las = 1, ...) ## ... } And, R claims now, on startup: [hello messages skiped ...] Error in .First() : couldn't find function "x11" > I commented

I am reading a list of numbers from my clipboard, and have been successful, except I can't make a histogram as R doesn't recognize my variable as numeric. I know I need to use "as.is", but the specifics escape me. I have used x<-read.table("clipboard", header=F) to import from a txt file. How do make this numeric? Thanks, J.

Dear R-experts! I have y(x) data, dim(y) == dim(x) == c(2000, 2) I'd like to fit them with nls: fit.result <- nls ( y ~ f(x, p1, p2, p3), start = list(p1 = ... , p2 = .. , p3 = ..) ) Actually I want to fit y[,1] ~ x[,1] and y[,2] ~ x[,2] *simulaneously*, with the same parameters set {p1, p2, p3}. I tried to feed R tha above formula, R errors with:
