Hi all, I have a string vector like that: x=c("1\t\t", "2", "3\t\t\t") I need to remove all the occurrences of "\t", in order to obtain: x = "1" "2" "3" I'm trying to use the function substring2, and it works for each component, for example: substring2(x[1], "\t") ="" gives x = "1"

Hi, I need to select a substring from the filename of a file in a list. I can find all the filenames in a directory by list.files(fn_dir) Each filename has the format (the following is an example because field lengths are variable) XXX184_YYY_ZZZ.dat XXX: 2 or 3 alphabetic characters 184: 3 numeric characters ... I'd like to select the substring XXX which has variable length (from each

Hi all, I'd want to plot a segment from a line specified by slope and intercept. I want to plot this line between two limits, x1 and x2, without imposing these limits to the hole plot as it is the case with scale_x_continuous(limits=c(x1,x2)) or with xlim and ylim. Any idea?

Hi all, I'd like to use the Hmisc::summarize function, but it uses a function (FUN) of a single vector argument to create the statistical summaries. Consider an easy case: I'd like to compute the correlation between two variables in my dataframe, grouped according to other variables in the same dataframe. For exemple, consider the following dataframe D: V1 V2 V3 A 1 -1 A 1

Hi all, I'd want to plot a table of numbers such that the values are represented by gray level. Is there an easy way to do that using ggplot2? Thanks, Arnaud [[alternative HTML version deleted]]

Hi, I'm trying to read some trajectory files (text files) which have the form: # trial n # t X Y 0 1 2 0.2 1 3 0.4 1.2 4 ... # trial n+1 # t X Y 0 1 2 0.2 1.3 3.3 0.4 1.5 5 ... ... where the symbol # means that the line is not a numeric value, but I still need to read the number of the trial (n=1, 2, etc.). I

Hey Folks, I''ve written a script to generate a list of all files on a machine, then zip the results. ?I''m going to stick a web front end on it, and use it to audit some file servers. The problem is that the ZIP compression/decompression isn''t working, but its not what you might think. ?The script completes, but seems to not actually write anything. Here is a short

Hi, I've a beginner question. I'm trying to extract data in my dataframe according to some nested rules. I have something like the dataframe test.df: test.df = data.frame(V1=c(rep("A",10), rep("B",10), rep("C",5)), V2=c(rep(1,5), rep(2,5), rep(1,5), rep(2,5), rep(1,5))) V1 V2 1 A 1 2 A 1 3 A 1 4 A 1 5 A 1 6 A 2 7 A 2 8 A 2 9 A

Hi all, I''ve got overlapped and offset support in both nread and nwrite. The only thing left before I want to release this (as 0.4.0) is to get NO_BUFFERING to work. Unfortunately, I can''t get it to work. Park, I looked at that site you sent (and borrowed some code from it), but I don''t see anything special happening for NO_BUFFERING. I thought it required

Hello everyone, I am running Ubuntu and have converted my CDs to FLACs (using all the paranoia and fixing all the tags etc.). What is the best way for me to convert all of those FLAC to ogg-Vorbis files, keeping all the tag information and the same directory structure? I am not wanting anything incredibly advanced, but was expecting something like vorbconvert /media/cd_rom/ /home/aaron/vorbis/

Hi! i am testing Louis van Belle backup script. it works quite well. Thank you for sharing this! https://github.com/thctlo/samba4/blob/master/backup-script/backup_samba4 but i think there is an error in the KEEP_DAYS code as the string '\-$KEEP_DAY1\-|\-$KEEP_DAY2-' is not interpolated so the egrep does exclude anything from rm call. So no files older than $DAYS are kept... # Remove

I think tools::Rd2HTML has a problem with the dl tag. Under some conditions, <p> and </p>, and <dl> and </dl> are not nested correctly. Here is an example from the "options" doc file: -- <p> <dl> <dt><code>save.defaults</code>, <code>save.image.defaults</code>:</dt><dd> see

Hi, I have spent a few hours on the R-exts manual and the documentation of parse_Rd() (as well as the PDF document in the references), but I still have not figured out what results=rd means. I thought I could use an R code fragment to create an Rd fragment dynamically. Here is an example, in which I was expected the output to be a describe list <DL> in HTML, but it turns out not to be true.

I've just committed some fairly big changes to R-devel. - There's a new tag \Sexpr which allows R code to be embedded within the Rd file, similar to Sweave, \RdOpts corresponds to \SweaveOpts. - The parser now mainly issues warnings, rather than errors, in case of syntax errors. It throws away a few tokens and tries to restart. This should let you see most of your errors in
