bonjour, je rencontre quelques soucis au niveau de l'utilisation des fonctions arima.forecast/predict; en effet elles sont dites inconnues alors que j'ai bien install?? et charg?? le package "ts". Aussi, j'aimerai savoir comment visualiser le graphique des pr??visions avec arima et celui des donn??es brutes dans la m??me fen??tre. Tout en vous souhaitant bonne r??ception

- Peut-on poser des questions en fran?ais? - Tr?s simple. Je fais un programme "truc.r" (sous emacs) Ce programme r?alise des graphiques. Je voudrais les enregistrer au fur et ? mesure -- sinon, quand la session est finie, ces graphiques sont perdus-- J'ai essay?: pdf("truc.pdf") Mais le fichier "truc.pdf" cr?? est vide. Comment fait-on? Merci et salutations Jacques Vernin

In conducting studies of animal orientation and displacement, I need to produce circular histograms of angles (bearings in radians 0-2pi) where the centre of the circle indicates very few observations for a given bin of angles and outwardly concentric circles indicate greater frequencies of observations for a given bin of angles. I'd like not to have to write the function myself but I

...utput, there are empty spaces on the x-axis. How would I eliminate these spaces? I want a nice, smooth, empty-spaceless x-axis. (2) How could I add tracing lines to each histogram? I am undoubtedly using the wrong terminology. What I want to do is something like this: http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=55 Note that each histogram has a tracing line that summarizes the histogram. In summary, I'd like to modify the code above to (1) get rid of the dead spaces on the x-axis, and (2) add lines that traces to each of the histograms therein (all on the same graph). I am...

...R Users, How to use the function polygon() together with the package scatterplot3d? I am trying to color below of the curves defined for the function density().

Hello everyone, I wanted to know if it was possible to change the color of certain leaves in a hclust object in order to make my graph more readable. I know I can color certain groups but I would like to enter a vector telling the plot function which leaves to color in which color. Thanks in advance, William.

Hallo everyone, I want to evaluate the change of the distribution for several size classes. How can i order these separate histograms with the same y-axis along a common x-axis according to their size classes. It would like it to look a bit like this (http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=109) without the quantile regression. I can produce the separate histograms, but have no clue how to merge them. i can put them next to each with separate x- and y-axes. Much obliged, Kenneth -- View this message in context: http://r.789695.n4.nabble.com/Ordering-sever...

hello, does anyone know how to add histograms or distributions on regression like just like quantiles regression in RGraphGallery below, a very delicate codes. Thanks alot. http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=109

I need help creating a bubbleplot, like a simple pseudo three dimensional scatterplot of circles whose sizes index a 3rd variable. I initially came across this at http://addictedtor.free.fr/graphiques/graphcode.php?graph=73 but the circleplot function does not exist in fbasic as listed in the document. _________________________________________________________________ 50F681DAD532637!5295.entry?ocid=TXT_TAGLM_WL_domore_092008 [[alternative HTML version deleted]]

I intend to draw a plot of y against x. In the background of this graph I wish to creat a histogram of the horizontal variable x. Does any expert know how to produce such a plot? [[alternative HTML version deleted]]

Hi, in order to save space for a publication, it would be nice to have a combined scatter and density plot similar to what is shows on http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=78 I wonder if anybody perhaps has already developed code for this and is willing to share. This is the reproducible code for the histogram version obtained from the site: def.par <- par(no.readonly = TRUE) # save default, for resetting... x <- pmin(3, pmax(-3, rnorm...

Dear All, I have a question on overlaying a filled.contour (e.g. on soil properties data) and contour (by elevation) in one graph. Both have the same z matrix dimension. I'm able to overlay both graph, but the plots dimension did not overlap well on the same plots. How can I have both filled.contour and contour on the same graph? The commands that I have written are as follows:

Does anyone have a simple explanation and example on how to add histograms or barcharts to an other graph like in the example at the R-graph gallery: http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=109 looking at the code I'not undertand very well how to add graphs in arbitrary/clever position with an adequate scale. If somebody have a simplier example with explanations it will be highly appreciate. Best Daniele ------------------------------------------------...

I've looked long and hard for this, but maybe I am missing something... There is a nice module that displays histograms reflected in the y axis, i.e. http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=136 but is it possible to reflect in the x-axis, so to have two datasets, one pointing up and one down rather than left and right? I haven't been able to find a way to plot this way using the guide, or elsewhere. Thanks... -- View this message in context: http://www.n...

...Some time ago, in a gallaxy far away (here is the thread : http://finzi.psych.upenn.edu/R/Rhelp02a/archive/46532.html ) we discussed about a graph gallery showing the power of R in that domain. I did some work around that, and there is a (pretty advanced) draft here : http://addictedtor.free.fr/graphiques/displayGallery.php For instance, there are some of my graphs, some of Eric Lecoutre's and some coming from demo(graphics), demo(image), demo(persp) and so on. Pretty soon, I'll add the possibility to : - add graphs dynamically from the web - give a mark to each graph (maybe we can do so...
