-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Symptoms: curve with log x axis gets the wrong x limits (in 2.6.1, I believe introduced in this version). Credit goes to Mike McCoy for detecting the problem. Demonstration: x = 1:5 plot(x,5*exp(-x),xlim=c(0.1,1000),log="x") xvec = 10^seq(-1,3,length=100) lines(xvec,5*exp(-xvec)) curve(5*exp(-x),add=TRUE,col=2,lwd=3) I believe

Hello, everybody I run the following program, and depending on the size of eps I get different results. With eps=1e-05, the program calculates wrong values for x=65:67 and others. The program runs fine with eps=1e-07. Why is this so? Also, I am using area() instead of integrate() because I cannot make integrate to work, especially with imaginary numbers. Maybe someone can show me how to use

Hello, I tried this posted on the R devel subforum but no help so far. Maybe the wider net will be fruitful. Probably a pretty simple issue. The short story goes, I'm writing C source code and compiling it in as *.dll in the windows terminal by R CMD SHLIB foo.c. It works, I'm on a 64-bit system. I have the lastest R 2.15.0 and Rtools, and I am using the gcc 4.6.3 compiler. However,

Hi, I've got a matrix, Z, of values representing (as it happens) optical power at each pixel location. Since I know in advance I've got a single, convex peak, I would like to do a 2D parabolic fit of the form Z = poly((x+y),2) where x and y are the x,y coordinates of each pixel (or equivalently, the row, column numbers). Is there an R function that lets me easily implement that?

Hi, Suppose I have a multivariate response Y (n x k) obtained at a set of predictors X (n x p). I would like to perform a linear regression taking into consideration the covariance structure of Y within each unit - this would be represented by a specified matrix V (k x k), assumed to be the same across units. How do I use "lm" to do this? One approach that I was thinking of

Is it possible to have mail_max_userip set to a value for localhost (webmail) and to another value for everything else?

Hi, I'm using precompiled (for SCO OS5) 2.0.3. When my Win95 clients save a file to a share that already has a file of the same name samba upcases it. To be completely accurate the files in question have numbers as thier first 8 chars then an extension of .mtr. So, 19991115.mtr on Win95, when copied, becomes 19991115.MTR on the share if it's overwiting a file called 19991115.mtr that

Hi all, I have recently used the as.spikeTrain function in the STAR Packages but instead of using the CAL1S data that could be found in the package, I used data from other sources. I am able to convert the data into the required data frame but when I execute the as.spikeTrain function: datafile <- lapply(list_data,as.spikeTrain) It will give this error: Error in FUN(X[[i]], ...) : The

Hello, Novice programmer. I'm writing C source code and compiling it in as *.dll in the terminal by R CMD SHLIB foo.c. It works, I'm on a 64 bits windows system. I have the lastest R 2.15.0 and Rtools using the gcc 4.6.3 compiler. However, that was a hello world run, and I installed GSL for the 64 bit system for fast MCMC. The Rcpp package was easy to use, but I opted for a C with GSL

Hello List! I asked this before (with no solution), but maybe this time... I'm trying to project a surface to the XY under a 3d cloud using lattice. I can project contour lines following the code for fig 13.7 in Deepayan Sarkar's "Lattice, Multivariate Data Visualization with R", but it fails when I try to "color them in" using panel.levelplot. ?utilities.3d says there

Hi, I am new to R and am trying to do a loop but it seems not to run after one turn. What I want to do is subset my dataframe (extract one station and one day) to calculate and store the maxima that can then be plotted. I have an error message at the end of each loop: Error: unexpected '}' in "}" Here is my code: ********************************************* datafile <-

Dear R-users moving from Splus to R (under Windows), I notice that command "srt" within a plot in the original Splus code is ignored by R. For example, if a plot something and then include the line of code axis(1, at=Time, labels=Text, srt=45, adj=1) the srt=45 command within the axis() command fails to draw Text at 45 degrees on the x-axis in R but it works properly in Splus. I will

Rowland, yoy are right, It's the first thing I did but I don't know why I have no man for smb.conf     [root at dc2 ~]# man smb.conf     No manual entry for smb.conf Perhaps is because I built samba from source and I omitted some option in configure...
