Dear R users, I am just starting with R and am currently needing a lot of help! Sorry if I disturb you and thank you for your answers!!!

Dear R users, I am having a problem with the main title of a plot. I have written a function returning a plot and I would like that the main title of this plot shows actually the name of the dataset I have used. So, for instance: if my dataset is called Chl, I would like that my plot to be entitled : "Raw periodogram of Chl". I know the function "paste". I suppose I would be

Dear R users, I have been having a problem since I installed the new versions of TinnR and R on my computer (1.19.4.7 and 2.6.0 respectively). I used to open R by the command "start preferred RGUI", on the "R" tab of TinnR's menu. But now, since I updated both softwares (which was necessary for some compatibility issue with Windows Vista), the path for my preferred RGui (

Hello R users, I have been looking through Help files and Nabble list for the answers for these simple questions, but it seems to be fruitless. 1- in a data frame with two columns, x and y, how do I get the corresponding value of x to, let's say, the minimum value of the y column (min (data$y)) ? 2- how do I solve a simple equation? Considering the equation y= exp(-x)^12, I would like to find

Dear all I have trouble with setting the size for jpegs and pngs. I need to save a dendrogram of 1000 words into a jpeg or png file. On one of my computers, the following works just fine: bb<-agnes(aa, method="ward") jpeg("C:/Temp/test.txt", width=17000, height=2000) plot(bb) dev.off() On my main computer, however, this doesn't work: >

doKeybd() gets called in CHelpKeyIn() and NHelpKeyIn() in library/grDevices/src/devWindows.c, where the call is encapsulated in an 'if (dd->gettingEvent)' block. So the only times this code ever calls doKeybd() is when gettingEvent is in fact set. Further, it's called in two locations in X11_eventHelper(), in modules/X11/devX11.c, where the state of gettingEvent seems to be moot

Hi, After I installed R in my computer, I have loaded package Faraway, but when I want to plot, it will show errors like below: *> x<-c(1,2) > y<-c(3,4) > plot(x,y) Error in windows() : unable to start device devWindows* I don't know why, please help me. Shuyan [[alternative HTML version deleted]]

Dear R users, I need to save a graph in jpeg format. After plotting the graph, when the graphics window is active, in the File menu, the Save as / Jpeg / 100% quality correctly saves the graph in jpeg format. But I would like to know, how could I control the resolution (in dpi) of the saved jpeg file? I need to produce a jpeg at 1200 dpi. I have tried also the jpeg function in the package

When I execute the following code, it works just like I want it to: three pages of nine (or fewer) plots. However, when I execute the code with the first and last lines uncommented, I get three pages (files), but the 2nd & 3rd pages have overlapping plots. It's like a new page wasn't created. I'm pretty sure I've either misplaced or left out a crucial call to some

Hi, I am having trouble saving graphics from R. jpeg() saves a file with the correct name to the correct directory, but it consists of a blank (white) jpeg with the specified dimensions--the image itself is not being saved.

Dear list, I am having troubles increasing the fontize when plotting a variogram{gstat} and its model (vgm) with plot and using jpeg(). Also the resolution in the jpeg call does not work. I am using R2.4 on Mandriva 10.2 linux. I can change fontsize with cex.axis in a normal plot, so I presume it has to do with plotting the variogram model. Any help on how to increase the font size and

Colleagues, Using R 2.10.1 in OS X (Snow Leopard), I created JPEG documents that were intended to include italicized text. In the JPEG versions, the italics appear in bold-face. The identical code (except for the call to the device) yields italics in PDF. A minimal example is: PDF version: > pdf("plot.pdf") > plot(1,1) > mtext(bquote(italic(P) < .(0.005))) >
