Hi I was searching for some X replacement for my job in R and i found the GDD I installed it and I match all the system requirements. My problem (maybe a dumb one) is that every plot comes with no font and i cant find a simgle example of a plot WITH FONT DETAIL in the list can anybody help me? a simple example: library(GDD) GDD("something.png", type="png", width = 700,

Hello everyone, I am working for a few days already on a basic algorithm, very common in applied agronomy, that aims to determine the degree-days necessary for a given individual to reach a given growth stade. The algorithm (and context) is explained here: http://www.oardc.ohio-state.edu/gdd/glossary.htm , and so I implemented my function in R as follows: DD <- function(Tmin, Tmax, Tseuil,

hi I'm using the GDD package (in a 64bits fedora machine using R 2.3.0) to save in a png file some plots and i noticed that changing the lwd parameter does not change my line width I tried the same script in a Windows based R (2.2.1 r36812), using no GDD, and it worked. Does anybody has a clue? My testing script is something dumb like this: library(GDD) GDD("pres24.png",

I'm using R embedded in PostgreSQL (via PL/R), and would like to use it to create images. It works fine, except that I have to create every image in a file (owned by and only readable by the PostgreSQL server), and then use PostgreSQL to read from that file and return it to the client. It would be much nicer if I could plot images into an R variable (for instance, a matrix), and return that

Hi I am using R 2.2.1 under Linux (SuSE 10) and would like to know if it is possible to create graphs, i.e. jpeg(filename=fn) try( coplot( mor$I_Morisita ~ mor$Year | mor$RunStr, show.given=FALSE) ) dev.off() from a text console? It gives me an error message on the jpeg() command: Error in X11(..snip..) unable to start device jpeg In addition: warning message: unable to open connection to

Hi, I noticed recently when installing the GDD package for R under GNU/Linux that it required the gd library (http://libgd.org/) for generating graphics. The resolution of this was to simply install the library on my system, and then GDD successfully installed without any complaints. However, the variant of GNU/Linux that I use is Gentoo, so I filed a bug requesting that a USE flag be set for

Hi there I'm looking for a function to read PNG-bitmap-images from a file into R. I only found: - the pixmap-package which cannot import png or similar formats - the rimage-package which can only import lossy jpeg-images (the convertion from png to jpeg modifies the data!) Is there any possibility to read PNG-files? Thanks for any help Dominic Sydler

I would like to save graphics I produce in jpeg or gif formats. The GDD package sounds like it should let me to do this, but I cannot get it to install (error: Can't find gd.h!). Anyone know what's up? Thnx, C

Hi Community, here is the problem, Linux problem (reported to work on Windows). I need to generate graphical output in any of bitmap format under the 'R CMD BATCH'. Whereas the script generating png-s works perfectly in the R session, such things as X11, png and jpeg are not usable in BATCH (they cannot be switched on by --gui-X11 etc) and X11 is prompted to be required for png.

Hello, I'm trying to adapt some R code that works on Windows so that it will work on a Linux machine. The command : png("myFile.png", width=600, height=600) fails claiming that it is impossible to establish a connection with X11. (Error messages are in French, so I'm not pasting them here!)

Dear Colleagues, We are attempting to create trees using R with our Ruby on Rails application. However, we are running into a problem involving the creation of the graphic. We would like them to be in either jpg or png format so that users can save, but due to a lack of control over our sever we are unable to start X11 server. Is there a way to create these images without using X11 server?

OK, my journey to make lab machines automagically install & update all desirable R packages is nearing an end! The only question I have now is this: How can I control where the system prints the *.Rout file that is created automatically when the R batch program runs. In "man R" I don't find any information about it. When the cron job runs "R_installAll.sh" (see

Hello, When launching R from a script, when queried it reports the following capabilities as false: jpeg, png, x11 and cledit. When R is run from a terminal session, all of these capabilities are reported true. R is running on FC4. As the purpose of this script is to output the png file to a browser, it is unable to complete because of this. Any ideas are appreciated. We have an identical

Hello all. I have been given an assignment to mount a share automatically for each user using a given Linux machine (Mandrake 10 in this case).

The problem I'm having is that when I mount these on Linux the '?' looks like 'o' but cannot be accessed like that. It
