Subset based on items in a list.
R-help: I have a variable ("ID_list") containing about 1800 unique numbers, and a 143066x29 data frame. One of the columns ("ID") in my data frame contains a list of ids, many of which appear more than once. I'd like to find the subset of my data frame for which "ID" matches one of the numbers in "ID_list." I'm pretty sure I could write a function

External USB Drive partitioning and formatting
Hi, I just bought a Seagate 1TB USB drive thinking that I could create a few partitions in it, format in ext3 fs, then configure bacula to setup a backup server in my CentOS box and backup my windows and mac clients. I have plugged the drive and mounted in /mnt/usbdrive and is seen as /dev/sdb1 by the OS. The output of df command is: [root at Production ~]# df Filesystem 1K-blocks

I have 2 vectors, x and y and have done an xy plot. I want to plot the label (name?) of the vector on the plot rather than the value. text(x,y, labels = x) gives me the value of x. text(x,y, labels = labels(x)) gives me something like c("text1","text2"..) plotted for each point text(x,y, labels = names(x)) gives nothing print(x) gives me [,1] text1

buggy HTML from nested lists w/ paragraphs
I ran into a weird problem while writing my own little guide to Markdown (using Markdown, of course). The document is mostly made of list items in nested ul's. As I neared the end, I found (via MarsEdit's preview) that in place of two sections of content, Markdown had begun to generate gibberish strings like this: aa9ca05a7c006bc5e5c091c00aee0cd7 After weeding through different

Converting a matrix to a dataframe: how to prevent conversion to factor
Colleages I am running R 2.1.0 on a Mac (same problem occurs in Linux). In some situations, I have mixed text/numeric data that is stored as characters in a matrix. If I convert this matrix to a dataframe, the numeric data becomes factors, not what I intend. TEXT <- paste("Text", 1:4, sep="") NUMBERS <- 10 + 4:1 MATRIX <- cbind(TEXT,

wxruby swig progress
I''ve checked a number of new .i files into the wxruby-swig tree. Not all of them are fully tested, but I thought it would be better for them to be there than to have somebody start duplicating the work. I''ve also added the ''caret'' and ''image'' samples, as well as the generic etc/test.rb. These need the unreleased SWIG-1.3.22. The current

possible to plot number line in R?
Hallo! Is there a possibility to plot a number line in R? I would like to display 3 different Intervals on the same number line. Ideally, it would be possible to add a name to each number (e.g. Interval 1, lower cut-off...and so on). I have not found a command for this. Thank you for your help.
