I am encountering problems using the png() function to save around 20 charts to separate files. My script is conceptually structured as follows: ### <script> png("Image %03d.png") # the following are calls to user-defined functions I wrote that call plot, barchart, etc. with special arguments. myPlot("a") myPlot("b") myPlot("c")

Hi, I just started using R and am having trouble with the below error: I type: > df <- read.csv("/home/rex/Desktop/mytable.csv") which gives me what I want: ... 639 2006-05-26 16:46:54 4 16 640 2006-05-26 17:05:36 5 17 641 2006-05-26 17:30:48 6 17 But now I try: > plot(df[4],df[3]) Error in pmatch(x, table, duplicates.ok) : argument is not of

I would like to draw a set of points that are equally spaced in a 2-D grid. Then I would like to draw lines that illustrate different directed paths through subsets of points. Imagine that the points correspond to booths in a conference center, and I want to show the various paths people took to visit the booths (using color to highlight different types of paths). An example path might be: [(1,1),

When I use barchart (with default formatting options), I get bars whose lengths/heights are not proportional to their value. For example: http://drop.io/wbagm6s/asset/capture-png Many of the values in this chart are 1; however, because the blue bars extend to the left of the "0" tick mark, those bars appear to represent higher numeric values. Is there a way to make the length of the

How can I write text inside a bar of a barplot? I tried using text(), but I am only able to specify the numeric y-coordinate. The different columns of my barplot correspond to factors and not numbers, so I don't know how to access the horizontal positions of the bars. I tried fiddling with different values of the "adj" argument, but this appears unreliable. Background: I have

Hello, I just installed Instant Rails on my Windows XP box. I would like to test out the Ruby interpreter on the command line. However, when I run C:\InstantRails\ruby\bin\ruby.exe from the Windows command prompt, it hangs. Any ideas on how I can get a Ruby command line?

Let's say I have data in the following schema that describes the number of purchases a company has received from each County in the US: State | County | Purchases --------------------------------------- NJ | Mercer | 550 CA | Orange | 23 .... I would like to visualize what states contribute the most to the overall total, and furthermore within those states, what Counties contribute the most.

Hi, I get * excluding invalid files from 'R.oo' Subdirectory 'R' contains invalid file names: attachLocally.Object.Rex Exception.Rex extend.default.Rex InternalErrorException.reportBug.Rex Package.Rex Person.Rex Rdoc.Rex setMethodS3.Rex StaticFields.Rex when running R CMD build in R v2.3.0 devel.

Hi, I am having a really strange problem with my Samba shares on Debian Buster. None of the users can access any shares, which reside on ZFS-filesystem. Any other share works just fine. For example, if I create a normal folder to /home with same permissions and replace a ZFS-share with that, it works fine. When accessing any ZFS-shares the following error is recorded: Jan 08 22:39:56

I added one testshare /home/testijako and connected to it with the same credentials as I would connect to ZFS-shares. Then I did the strace to that particular PID and tried connecting to one ZFS-share. There was indeed an error which might have something to do with this issue: Line 2001: lstat("/tank/rex", 0x7fff1f6fb2c0) = -1 ENOENT (No such file or directory) Im sure that folder

Hello Prof. Harrell and dear R-help mailing list, I wish to perform a non-parametric repeated measures anova. If what I read online is true, this could be achieved using a mixed Ordinal Regression model (a.k.a: Proportional Odds Model). I found two packages that seems relevant, but couldn't find any vignette on the subject: http://cran.r-project.org/web/packages/repolr/

Greetings, The following question has come up in an off-list discussion. Is it possible to construct a regular expression 'rex' out of two given regular expressions 'rex1' and 'rex2', such that a character string X matches 'rex' if and only if X matches 'rex1' AND X does not match 'rex2'? The desired end result can be achieved by logically combining

I have a heavy DATA saved in dbf format. What I want is to bring that data to R with SQL statements. Like: I want columns 1, 4, 5 and only when column 4 > 30. Sorry asking it here instead of keep searching in manuals, but it seems that there are too many ways of doing it. So what's the appropriate package that I need to work it, considering also that im dealing with lots of gigas so the

Create an object hierarchy to represent different bootloaders for Linux guests, moving the separate handling of grub1 and grub2 in different classes: this isolates the code for each type of bootloader together, instead of scattering it all around. This is mostly code refactoring, with no actual behaviour change. --- po/POTFILES-ml | 1 + v2v/Makefile.am | 2 + v2v/bootloaders.ml

hi, i think the current X86 disassembler is quite broken and fails badly on handling REX for x86_64 code. below are some examples: $ echo "0x0f,0xeb,0xc3"|./Release+Asserts/bin/llvm-mc -disassemble -triple=x86_64 .text por %mm3, %mm0 $ echo "0x40,0x0f,0xeb,0xc3"|./Release+Asserts/bin/llvm-mc -disassemble -triple=x86_64 .text por %mm3, %mm0 $ echo

Greetings - After 20+ years of using SAS, for a variety of reasons, I'm using [R] for a bunch of things - while I'm getting a pretty good a handling [R] for script programming, and statistical analysis, I'm struggling with 'pulling data into [R]'. For reasons beyond my control, a number of the files I get sent to 'work with' are in Dbase format (*.dbf). For
