Hello All, The attached patch allows openssh to specify which pam service name to authenticate users against by specifying the PAMServiceName attribute in the sshd_config file. Because the parameter can be included in the Match directive sections, it allows different authentication based on the Match directive. In our case, we use it to allow different levels of authentication based on the

I have the same question that Eusebio had: Is there a function similar to "sink" that redirect also R code to a file that is: sink("R001") x <- c(2,-6,-4,8,5,4,1,3,4,-9,0,1) A <- matrix(x, ncol=3) A A.prima <- t(A) A.prima dim(A) dim(A.prima) sink() create a file "R001" with contents: ------------------------------------------ [,1] [,2] [,3] [1,]

Sorry for the off-topic (non-R) post. Has anyone seen/tried this (from this week's NA-digest)?

Hi, [I'mm cc-ing r-help on this, since some others might be interested (Tony Rossini is, at least)] Yes, I saw your mail and was wondering about what would be the best approach to do it. It's definitely not trivial, mainly because Trellis is not designed to handle factors on the x-axis (chiefly for convenience, as factors typically have long names which are difficult to write on the

Karline, Thank you for your help. I discovered that in addition to including clim, I needed to omit breaks. This code uses one of your other examples as a starting point and works as intended: persp3D(z = volcano, zlim = c(-60, 200), phi = 20, colkey = list(length = 0.2, width = 0.4, shift = 0.15, cex.axis = 0.8, cex.clab = 0.85), lighting = TRUE, lphi = 90, clab =

Hi I am facing a problem where I would like to import a TIFF image (of spots on a nylon filter) into R (into a matrix for example). When plotting the matrix using fx. scatterplot3d I would then be able to see how the pixel-intensities are distributed in "spot-areas" on the filter - which would be very helpful. Does anynone know of a way to do this? Best regards, Peter Hagedorn ...

Folks I have a request to set up 2 types of access to the same Samba share. So far I've not had any luck getting this to work. The owner wants two groups to have different levels of access to the same share. One group needs read/write access, the other needs read only. Can someone tell me how to do this? This is not a publicly accessible or browseable share. The Samba servers is RHEL5

The handy function summary() doesn't work correctly with Date class objects: > R.version.string [1] "R version 1.9.1, 2004-06-21" > b <- as.Date(c("2002-12-26", "2002-12-27", "2002-12-28", "2002-12-29", "2002-12-30")) > b [1] "2002-12-26" "2002-12-27" "2002-12-28" "2002-12-29"

Hi folks: This may be a stupid question, but I cannot seem to find a way to tell readBin that I want to read 2-byte integers from the connection. The input file is 150,720 bytes long containing 75,360 short (2-byte) integers. But specifying "integer" or "int" for what in readBin only returns me a vector of length 37680, leading me to believe that sizeof(integer) or

I can't get Emacs to automatically do syntax highlighting of Sweave files. I have followed Friedrich's suggestion for code to insert into my .emacs file. The complete section from my .emacs file is given below. When I load a *.Snw file, font is white until I press M-x, then the first code and document chunks get highlighted, but not the rest of the file. Latex and Noweb menus are

Hi folks: I think I'm having problems with figuring this one out: test1 <- function() { n <- 2 for(i in 1:n) { cat(paste("i =", i, "\n")); flush.console() n <- 5 # version 1 #n <<- 5 # version 2 #assign("n", 5, envir = environment(test1)) # version 3 } } I need the for(.) loop to run (say) n=5 times within the

I'm making some 3D plots with contour3d from misc3d and wireframe from lattice. I want to view them from below; i.e. the negative z-axis. I can't figure out how to do so. I would like my point of view looking up from below, with the z, y, and x axes positive going away. Can anyone tell me the correct settings for screen to achieve this? Here is what I've found so far:

Hi folks: I used to load a DLL fine up until R 1.5.1. The same DLL dyn.loaded under R 1.6.2 prints the following warning message: > dyn.load("C:/Rajiv/Bin/rpdate.dll") Warning message: DLL attempted to change FPU control word from 8001f to 9001f > Any indication as to what the warning means, and whether I should be concerned about it? The DLL is made from a pure C code,

When I generate levelplot figures with Postscript, the lines from the underlying grid (i.e., the x and y in z ~ x* y) show up as faint white lines in the output. If I have a dense grid, the lines wash out the contour colors. I can avoid the problem if I use png instead, but that brings up other problems. Any ideas for how I can get Postscript to not show those lines around the cells? Scott

I wanted a simple function for bilinear interpolation on a 2-D grid, and interp.surface() in the fields package didn't quite suit my needs. In particular, it requires uniform spacing between grid points. It also didn't have the "visual" reference frame I was looking for. Here is an alternative function, followed by an example. # A function for bilinear interpolation on a 2-d

Hi, I am doing composite plots with the package plot3D. One of my variables is qualitative and indexed to integers, and I would like the legend for it to have labels located at the integer values (midpoints), and not at the breaks between classes. In the example below, the Elev Classes legend has labels at the breaks and nothing at the midpoints. How can I show the class labels at 1:3, and not

Hi, I want to use a discrete color ramp with plot3D, and show NA values as white (default). I get unexpected results per the following. # as in help(slice3D) example: par(mfrow = c(2,2)) x <- y <- z <- seq(-1, 1, by = 0.1) grid <- mesh(x, y, z) colvar <- with(grid, x*exp(-x^2 - y^2 - z^2)) slice3D (x, y, z, colvar = colvar, theta = 60) # # use three discrete classes and colors

I have a 3D field of a scalar variable (x, y, z, value). Is there a way to generate a vector field from this data--gradient at defined points? I found the rasterVis package for 2D data, but as yet nothing for 3D data. Thanks, Scott Waichler Pacific Northwest National Laboratory Richland, WA scott.waichler at pnnl.gov

I searched CRAN for material on gant (or Gantt) charts, those schedule plots that look like horizontal barplots where the x-axis is time. Finding none, I wrote the following and am submitting it to the archive so that it may help someone in the future. plotfile <- "gant.eps" regular.color <- "lightgray" important.color <- "yellow" tasks <- list() #
