similar to: Reading JPG files within R

Hi all, I have successfully compiled and installed (OS: Linux Mandrake 9.2) the last devel version of R (ver. 1.9.0). All seems to go well, but now I cannot use the cursors for exploring back the command history (when I press the cursor key the following characters are shown: ^[[A , or ^[[B etc.). Hints and suggestions are welcomed. Thanks. Paolo -- ----------------------------- Paolo

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

Hello Rubyists, I need to generate barcodes (in UPC and codabar symbologies) and would like to know if anyone has done this with Ruby. From what I can tell, it would be possible to use the gnu-barcode [1] or barcodewriter [2] to generate a PostScript, then through RMagick (via GhostScript) take the file and create a GIF/JPG. These will really only be used for web display (to be printed

Hi, Dear Boissinot: 1. When I have irreducible CFG, I travel its nodes by DFS. search backedge for every node. After I finish one node, push it into a stack. [0, 1, 2, M] <---push. [0, 1, 2, M,...N] <---push. When resolving node M, find a edge from node N to node M, N is not in stack(M < N), It is a backedge. N is in stack(M > N), It is NOT a backedge.

Hallo, I'm using wine in Kubuntu. The only Windows application I'm using is http://www.jpg-illuminator.de/ (freeware). It's running without any problems with Kubuntu 11.10 (wine-1.3.28 ). But I just installed Kubuntu 12.04 (Beta) with wine-1.4-rc6 and get the following error message and a frozen jpg-illuminator: > $ cat /disk2/tmp/xxx > ~$ wine

Hi list, I've problem with JPG wallpaper, it never sync to my roaming profile. When logon to the next PC, right click properties on desktop, the setting is there but it never show the wallpaper. Anyone know why it's like that.

I've got a weird issue with our server. You can't write a jpg file to it. Windows just errors out. When I tried from a Mac it wrote it over, but then instantly disappears. The only possible option I know of is the VETO parameter. But we're not using that.

Ok, here's what seems to be going on. When a JPG is put into a share it inherits permissions of 540. When I chmod it to 740 it appears in file browsers. So the file is actually there, but invisible. But I've tried other files and everything else copies over with 740. Again, why? On Thu, Mar 30, 2017 at 10:56 AM Curtis Vaughan <cavaughan at gmail.com> wrote: > [global] > >

My original question had the subject of making jpg-image files with the bitmap-function. Firstly I was told, that the problem was in my ghostscript-installation which is called by the bitmap-function - not in R itself. I got a lot of good suggestions (also off-list) about what problems in my ghostscript-installation might give some low-quality font-sharpeness in my jpg-grafics produced by

I am having problems exporting a plot to a jpg file. I am first setting up a basic plot, and then opening up a viewport and overlaying grid.arrows onto the plot - I don't seem able to save this plot with the overlaid arrows to a file, can anyone offer any advice? I am using R-1.8.0 on Debian Linux. Thank you in advance, Laura

Dear R-users, I have created a bunch of R scripts that automatically create multiple plots, all saved in a pdf device. I initially chose pdf output in order to easily access to multiple plots in a single file. Now, I am trying to play with different devices, like png or eps and I realize that the settings I used to have nice plots in a pdf device are giving awful outputs with the other
