I am trying to read an Excel file using the following: a<-read.xls("mydata.xls", sheet=1) The file mydata.xls is stored in the working directory. However I am getting the following error. Can anyone help. Error in findPerl(verbose = verbose) : perl executable not found. Use perl= argument to specify the correct path. Error in file.exists(tfn) : invalid 'file' argument --

I''m building an app that needs i18n support across the entire database (i.e. localized attributes). In order to do this I''ve created a special HABTM join table that can be associated with _any_ other table: create table language_strings ( for_table varchar(255) not null, foreign_id int not null, language_id varchar(5) not null, attr_name varchar(255) not null, value text

In the context in which I am actually working it is necessary for me to build parts of a text string to place on a plot in two separate stages. The following toy example illustrates what I am trying to do: L1 <- substitute(list(paste("Bias in ", gamma,", "))) L2 <- substitute(list(beta==b0),list(b0=300)) plot(1:10,main=L1) # Works fine. plot(1:10,main=L2) # Works fine.

Dear list, I'm trying to produce a plot via xyplot with minimal sourounding white space. However, I cannot find the options in xyplot, ps.options or wherever which prevents lattice from drawing quite some white space around my plot. However, this is quite a problem for me as I want to produce an inset plot inside another lattice-plot. I'm using the panel function to open a viewport and

I am plotting three Pearson Type IV distributions. It looks like I have to plot the distribution with the highest value of y and then use lines() to add the two distributions that are shorter / have lower max values of y. The following code figures out which distribution has the max y value, plots it first and then uses lines for the other two distributions with a series of three if statements.

Hi folks! I'm trying to get a histogram legend to give me a filled box and a line. The problem is I keep getting both filled boxes and a line. How can I get rid of the second box from the code below? x<-rnorm(1000,mean=0,sd=1) hist(x, breaks = 50, main="Histogram of x",freq=FALSE, xlab=" x", ylab="Density",col="lightblue",

Hello all lattice experts! I'm currently trying to plot inset figures in my lattice graphics. The plot is composed out of two panels and in each panel I want to show an inset figure which is a closeup of the data in each panel. Thus in each panel I call xyplot again to plot the inset which I place in a grid viewport. Nevertheless, once my first inset plot is drawn, lattice aborts with an

Basically i am running input via rails into ffmpeg which is a shell program. Is there a way i can take the output of the shell and store it into a string? or any other form that i can manipulate. andrew p.s. i am trying to read the dimensions of a video file via ffmpeg and use this value in my rails app. -- Posted via http://www.ruby-forum.com/.

Hello: What would be the best way to Output Code in TextArea for a UI component? The Rails App View is pure HTML and JavaScript. 1.render in text for controller action and the text is the code string. The < and > etc can be passed as is in this mode. 2.Read a HTML Template File (containing JS and CSS references) in Public directory(?) that needs to be substitute some variables that were

Recently I've been working on putting a little language together using the llvm toolset. I think I've wrapped my head around some of the beginner bits (and a big "thank you" for the kaleidoscope tutorial). What I'd like to do now is to take my Module* and output either a C file for native compilation, or just directly output a native binary. I saw that llc can output C

Hi, as I am sending PCM-data over the stdin to ices2, i need a good mp3-player wich runs at the console and is able to output pcm to stdout. So far i tried mpg123 and xaudio, but each had problems. mpg123 wasn't able to play some songs, particularely with varibale bitrate and xaudio played some songs and afaik most mp3pro-shit in double speed, even if it's 44.1khz. Does anyone know a

Hello, How can one write the output of a GLM/GEE model to a text file, such that the results appear in text file in the same (or similar) format they appear in the R console? For instance, I have the following model: Traitresult <- compar.gee(Y~X, data = data, family = "binomial", phy = tree, scale.fix = TRUE, scale.value = 1) How would I write "Traitresult" to a text

Dear friends, summary() doesn't give a good ouput style,e.g.: grass soiltem airtem gheight humidity altitude diluo :38 Min. :15.90 Min. :17.70 Min. : 8.00 Min. : 0.2360 high: 43 huanghuacai:32 1st Qu.:19.32 1st Qu.:22.60 1st Qu.:40.00 1st Qu.: 0.3190 low :119 hucao :46 Median :20.20 Median :25.30 Median :60.00

Hi, I'm new to writing any kind of sound program and somewhat new to C. I am on linux and I've been trying to get the example code (http://www.xiph.org/ogg/vorbis/doc/vorbisfile/example.html)for the decoder using libvorbisfile to work. I think my main problem is output to /dev/dsp. If I use the example where the only change I made were to open a file instead of using stdin and I ouput

I am trying to plot a figure within a figure (an inset that shows a closeup of part of the data set). I have searched R-help and other sources but not found a solution. What I would like to do is (1) produce a plot (2) specify a window that will be used for the next plot (in inches or using the coordinate system of the plot produced in (1) (3) overlay a new plot in the window specified under (2)

Taking David's example further, here is a first try: id | name | description | more info -----+---------+-------------------+----------------- 6 | Inset | An inset element | just one element 8 | Stories | Another element | another element : with 2 lines, without : colons on the left. 9 | Other

i'd like to plot a legend in my diagram. The diagram will be included in a TikZ LaTeX document later. I tried the legend() function, but - it can not find a good place it self where the legend fits and playing around with coordinates and scaling consumes a lot time - standard settings for the text need adjustment (linespacing is quite large and so on) Is there an alternative to

Legend titles work in linear plots: curve(1/x, xlim = c(0, 1)) legend(x = 'topright', inset = 0.04, legend = '1/x', lty = 1, title = 'Legend Title') But when you change to a log plot on either dimension things get screwy: curve(1/x, xlim = c(0, 1), log = 'y') legend(x = 'topright', inset = 0.04, legend = '1/x', lty = 1,

Dear R gurus, I am trying to plot a legend in the margins of a figure. The basic idea is to have two (or more) plots on the same figure, but then to have a common legend at the bottom of the plot. The approach that I have taken is to setup the figures, then do a "dummy" plot of the legend to determine the height of the legend box (ie from the value returned by the legend() command). I
