I have a library of .pdf and .doc files in the public folder of my Rails app. What''s the best way to configure routes.rb so that I can provide links to download these files from my webrick server? -- Posted via http://www.ruby-forum.com/.

Sorry, I am sure, this must be documented somewhere (but there are that many docs and tutorials to scan for topics..., actually a great thing... but if you are in a hurry..): I want to save a plot as .ps (or .eps): > postscript("plot1.eps", horizontal=FALSE, onefile=FALSE,height=8,width=8,pointsize=10) > plot(hpfit$fit,rstudent(hpfit),xlab="Fitted

When I save a particular plot as JPG or BMP, the saved image is an accurate copy of that plot. But when I save the same plot as EPS or PDF, some text elements are incorrectly altered. An example is attached. Notice in the top middle and top right panels, the x-axis labels have correct subscript 1 in the JPG, but incorrect subscript 2 in the EPS. I'm using R 2.13.0 on Windows 7. Any clues

Hi I didn't find this in the manual: I need to change the width of a plot while I use sweave, so which command/parameters should I insert below, to change the width of a plot \begin{figure}[htbp] \begin{center} <<echo=TRUE, fig=TRUE>>= plot(Re(q),ylab ="",type="o",col="blue",lwd=1, sub=mystring) @ \caption{Original stick function (stimulus

gday R friends, I was wondering if anyone could help me with some graphics issues please. I'm processing R in batch on redhat6.2 with some graphics to be imported into msword on NT. For scaling within my doco I want some vector type graphics. win.metafile doesn't seem to be supported on redhat which gives me postscript. postscript is ideal but doesn't contain a preview so I

Here's the problem: [ben at kepler tmp]# file -i presentation.ppt presentation.ppt: application/msword I see lots of references to this problem, (EG: IMP, PHP bug, etc) all of which conclude, in various forms, "the problem is in your /usr/share/magic.mime, go away". But nowhere (that I've been able to find) is there actually a solution - and even the magic.mime file from

Hi, I'm trying to install Microsoft Word 2002 on Wine, version 1.1.0, running on ubuntu hardy heron, from a dvd called Microsoft Works Suite 2004 (German) that came bundled with my computer, and I've run into some kind of endless loop. This is what happens: - I d-click setup.exe on the dvd, wine starts and the setup menu is shown. - I select custom setup and click the

Hello Rusers, I have worked on a R Wiki page for solutions in exporting R graphs, especially, the often-asked questions: - How can I export R graphs in vectorized format (EMF) for inclusion in MS Word or OpenOffice outside of Windows? - What is the best solution(s) for post-editing/annotating R graphs. The page is at: http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-misc:export. I

Hi, After following advice from you good folks, I gave mongrel a try in a cluster design based on the example on the Mongrel website - and it worked right out of the box which is great - and it''s very fast :) I have got a bit stuck though. I have two MS Word files in /public/files/. I can pull back these files no problem but it isn''t sending a mimetype. I think I have two

Hi, I'm experiencing recently happend kernel panics while making bacula backups on my external USB harddisk. It first happened some days ago while I was running 6.4-PRERLEASE. I then updated to 6.4-STABLE and enabled all the kernel debugging stuff. I've uploaded "screenshots" (including backtrace) here: http://pics.pofo.de/gallery/v/misc/ I'm now not sure if the external

Is there a way to simply copy all the Windows software I installed on one machine to another machine? At this time it's just IE6 and MSWord but there may be more Windows software installed in the future... Markus Winhard

it seems that word can not read encapsupalted postscripts generated by R I used this command postscript("output.eps",horizontal=F,onefile=TRUE) since onefile=TRUE produces an encapsualted postscript actually what I'm trying to do is to insert the postsript file into a word document since other formats like jpeg and bmp do not reproduce the same quality like postscript formats any

I have the following two methods: def ProductFile::find_images(mode, prod_id) # convert to symbol in case it is not (most commonly it may be a String) mode = mode.to_sym case mode when :all, :first ProductFile::find(mode, :conditions => ["product_id = ? AND file_type LIKE ?", prod_id, "image%"]) end end def ProductFile::find_documents(mode,

Hi There, I have created the following function format<- function(){ repeat { form<-readline(paste("\nIn what format do you want to save these plots?\nChoose from: wmf, emf, png, jpg, jpeg, bmp, tif, tiff, ps, eps, or pdf.\nNote: eps is the suggested format for publication quality plots.\nPlot format --> ")); cat("\nI'm sorry, I don't know what that format

Hi I need to define the following c("one group" = class.weight[2], "other group" = class.weight[1]) #class.weight = c(1,2) but I don't like the hard-coded way and would like to use my.group <- array(c("one group", "other group")) but now c(my.group[1] = class.weight[2], my.group[2] = class.weight[1]) gives an error how can I solve this

again, under another subject: sorry, maybe an all too trivial question. But we have power data from J frequency spectra and to have the same range for the data of all our subjects, we just transformed them into % values, pseudo-code: power[i,j]=power[i,j]/sum(power[i,1:J]) of course, now we have a perfect linear relationship in our x design-matrix, since all power-values for each subject sum up

Hi the list, I used savePlot to export some eps graph but it seems that the graph file hold a bug. I include the graph.eps in a LaTeX file. Running latex is ok. But the dvi file contain some mistake, the graph overprint on some text and hide it. Then, when I try to convert it to another format, I get : Ignoring remaining special text following unkown PS operator: "SDict" Remainder

Hi I need to overlay two pixmaps (library (pixmap)). One, a pixmapGrey, is the basis, and on this I need to overlay a pixmapIndexed, BUT: the pixmapIndexed has set only some of its "pixels" to an indexed color, many of its pixels should not cover the basis pixmapGrey pixel, means, for this "in pixmapIndexed not defined pixels" it should be transparent. What would you

Hi all.... Admittedly I''m new to Rails and trying to find my way but I''m having an issue with uploading documents with attachment_fu. I have a form where I''m uploading multiple attachments (using AJAX to add file_filed_tags). That seems to work pretty well. The problem is I can''t seem to get the content_type to work as I would expect. For example, if I use
