When I mistakenly use file.copy() with a directory for the 'from' argument and a non-directory for the 'to' and overwrite=TRUE, file.copy returns FALSE, meaning it could not do the copying. However, it also replaces the 'to' file with a zero-length file. dir.create( fromDir <- tempfile() ) cat(file = toFile <- tempfile(), "existing file\n")

I was running some sample code from a help page tonight and wished to redirect the sample output to my Desktop under Linux (Mint-Debian 64 if it makes a different). I was surprised to find that file name expansion using the ubuquitious "~/" was not recognized, in fact it caused R to crash. Is this expected behavior? See my output below and sessionInfo(). Also, not shown, but

From: Hung-chi Lihn <hlihn at google.com> The current Lua.c32 does not enable io.read() due to some missing library functions. However, this strongly limits the Lua script from getting user inputs and reading files (even in pxelinux via TFTP). This patch enables io.read() in Lua.c32 with some restrictions: 1. the io.read("*line") is fully supported. 2. the

The Rgraphviz package index says nothing about reading "dot" files. (it has "toFile" to write them but no fromFile). How do I create an Ragraph object? (either by reading a dot file or from a list of edges with weights and vertices with names and other attributes). -- Sam Steingold (http://sds.podval.org/) on Ubuntu 12.04 (precise) X 11.0.11103000 http://www.childpsy.net/

Dear all, I am finding difficulty in the following, I would like to create an empty matrix e.g. 10x10 of 0s and sequentially fill this matrix with randomly placed a 1s until it is saturated. Producing 100 matrices of sequentially increasing density., This process needs to be randomized 1000 times., I assume i should run this along the following lines, 1) Create 1000 matrices all zeros, 2) add

Hello. I'm trying to add option to grub menu (amongst other options) to boot from squashfs image. But 'root=live:/path/tofile' doesn't work. I didn't find anything useful on the internet. Anybody can point me in right direction? Maybe better choice is to replace grub with isolinux? I have working solution with iso with squashfs booting through PXE, but i don't know how to
