Hi, I am very very new to both Ruby and Ruby on Rails. I have been given a task to create a web application, which is able to edit individual entries in a key-value file. In other works, I would need to create an application which can parse a key-value file. Could someone guide me where I should start in a case like that? I was able to access and edit database table entries using Rails, but I

Hi all, There must be a really obvious R solution to this, but I can't figure out how to aggregate a list. For instance, if I read.table the following from a file: Val1 Val2 A 3 4 A 5 6 B 4 4 I would like to take the mean (or median) across any/all rows of type "A" to end up with the structure: Val1 Val2 A 4 5 B 4 4 in this case. How would I go about doign that w/o doing a

Hello, Apologies if this is a stupid question. I googled and skimmed the archives and didn't see anything specific about this. I am documenting an analysis procedure in a DB and I would like to know the specific version number of each package that I use. Is there a standardized way of getting that information out from R, or should I parse it out from the source-code files? Ideally I

Can you think of any reason why for about 220G of files (about 4...

Hi all, I would like to apply a function to each column of an 2-dimensional array, and store the result in a new 1-dimensional vector. I am not sure how to go about doing that syntatically. For instance, can I use lapply? And, if so, how do I specify which dimension should be used? Also, how do I pre-specify the type of object that will go into the 1-dimensional vector. I'm not sure if

Hello Axel, I'm an undergraduate student who has been working on a student project implementing a project like this for our Fourth Year Design Symposium (http://eceprojects.uwaterloo.ca ). Our VHDL decoder is targeting an Altera FPGA (Cyclone II), however I think that much of this would hold for your students project as well. The project took significantly longer to complete than we

I'm running rsync 2.5.5 on a FreeBSD-CURRENT system. I have a directory that essentially is my web site, which I update when need be. I am (trying) to use rsync to sync a remote server with my changes whenever they are made. I'm using a little script to do this: #!/bin/sh DATA_DIR=/home/munish/data/www REMOTE_BACKUP=[snipped out user@host here] RSYNC_FLAGS="-zapuLxSC --stats

Hi all, I have a data.frame e3. I use a function on it: n3 <- normalize.qspline(x = e3, samples = 0.07, na.rm = TRUE); The resulting data.frame has lost it's row-names and column names. This is the natural behaviour of the function I am calling, and I can't alter that at the moment. However, the data *is* in the correct order, as it was initially -- the names are just missing in

All of the rsync pages say that "rsync -a --delete src dest" will do a full mirror but it just isn't so for us. I've only found one Google item similar: http://www.linuxquestions.org/questions/linux-software-2/rsync-doesnt-seem-to-delete-599985/ We have around 9200 directories in 250G in /home on a Sun 4500 with Solaris 8 and rsync 2.6.5 - which we are trying to mirror on Sun
