Initializing vector and matrices
...u intend to use. This works with a few megabytes of data. It is not very efficient, so scaling up may become a problem. m22 <- matrix(NA, 1:600000, ncol=6) It does not work to add a new column to the matrix, as in you get an error if you try m22[ , 7] but convert to data frame and add a column m23 <- data.frame(m22) m23$x7 <- 12 The only penalty that I know of to having unused space in a matrix is the amount of memory it takes. One side effect is that your program may have a mistake that you would normally catch with a subscript out of bounds error but with the extra space it now runs...

Initializing vector and matrices
x <- numeric(0) for (...) { x[length(x)+1] <- ... } works. You can build a matrix by building a vector one element at a time this way, and then reshaping it at the end. That only works if you don't need it to be a matrix at all times. Another approach is to build a list of rows. It's not a matrix, but a list of rows can be a *ragged* matrix with rows of varying length. On Wed,

How to automate SMBMNT
Hi there, How do I automate smbmnt so that when logging on, it mounts the required shared directories on an NT4.0 file system using the user name and password I used t gain access to the GUI ? I s this possible. I am currently running Network Neighborhood and have been using this application for access but this requires that I scan mount and log-on again before gaining access to that share.

[ARM] Should Use Load and Store with Register Offset
Hello Sjoerd, Thank you for your response! I was not aware that -Oz is a closer equivalent to GCC's -Os. I tried -Oz when compiling with clang and confirmed that the Clang's generated assembly is equivalent to GCC for the code snippet I posted above. clang --target=armv6m-none-eabi -Oz -fomit-frame-pointer memcpy_alt1: push {r4, lr} movs r3, #0 .LBB0_1: cmp

passwords for Samba mounts in /etc/fstab
I am trying to create a samba mount to be mounted automatically on a Redhat 7.2 machine. I can mount the drive from the command line, but would like to have the drive mount on boot. I have added it to /etc/fstab, and get prompted for a password when I run mount on it from the command line. I know it is possible to pass the "password" option, or the "credentials" option to
