Hello, I am trying to wrap my head around the coordinates systems associated with the layout() function ...with the end goal of simply drawing a decorative line in the upper margin of my figure, which is composed of three plots. My output is defined as this: ---------------------------------------------------------------------------- postscript("out.ps", horizontal=FALSE,

Hi R users, I made a few research on how to convert inches into centimeters for graphics settings (especially width and height of the graphic device). Apart from the function layout() wich can be settled in centimeters using lcm(), I found that writing a function that convert centimeters into inches (i.e. x/2.54) was probably the best answer. Is there somewhere any parameter that could help

Is it possible to add lines or other user defined graphics to a plot in R that does not depend on the user scale for the plot? For example I have a plot plot(x,y) and I want to add some graphic that is scaled in inches or cm but I do not want the graphic to change when the x-y scales are changed - like a thermometer, scale bar or other symbol - How does one do this? I want to build my own

Here is a potential wishlist item for adding an argument (asp) to symbols(). The following code produces a postscript file with two pages; both should show a circle of radius 2 units. Horizonal and vertical arrows are drawn to check that the circle is of the correct radius; in the first plot, the circle is wrong. To fix this, I found that I needed to first set up the plot bounds, using xlim,

Dear useRs, Why are the rotated blue and yellow boxes in the example below clipped outside of 6 x 6 inch window in the middle of the page?? Where does the 6 x 6 inch window come from? I would like to make use of the entire page. > library(grid) > pdf(file = "FarmMaps.pdf", paper = "a4") > pushViewport(viewport( + width = unit(7.6, "inches"), height =

Dear list, I need to align two plots on top of each other for comparison (they only have the x-axis in common). When the y-labels have a different extent, I cannot find a way to align the x-axes, as illustrated below, > library(grid) > library(lattice) > x <- seq(0, 10, length=100) > y <- sin(x) > y2 <- 10*sin(x) > f <- rep(c("1", "2"),

I am trying to plot a figure within a figure (an inset that shows a closeup of part of the data set). I have searched R-help and other sources but not found a solution. What I would like to do is (1) produce a plot (2) specify a window that will be used for the next plot (in inches or using the coordinate system of the plot produced in (1) (3) overlay a new plot in the window specified under (2)

Hello, I'm trying to determine the width of a plotting point (in inches) in the grid package. I naively thought I could create a pointsGrob with only one point and get the width (as tried below), but this results in an object with a size of 0inches (changing cex has no effect). Does anyone have a better approach? Of course, it would be dependent upon the graphics parameters and viewport...

Dear R People: When using the jpeg function for plotting, is there a way to set the size in inches, please? There is an option for width and height in pixels, but not inches. Any suggestions would be welcome!!!!! R Version 2.2.1 Windows Thanks in advance!

Dear list, I would like to plot arrows with different colors according to arrow length, and also (if possible) with head size proportional to arrow length. The idea is to make a quiver-like plot of matlab with wind speed data. So far, I´ve been able to use different colors, but I need to find a more efficient way to recode arrow length intervals into colors. On the contrary, I can't define

hi all - i'm having some difficulty figuring out how to convert between "user units" (which i can't find a definition for in the plotrix package) and either (a) device units (e.g. inches with PDFs) or (b) user coordinates along any particular axis. as an example, suppose i set up a PDF device with inches, the device has both outer and inner magins, and the plot region has

Good Afternoon All, I am working on a project to generate a particular celeration graph that requires a very specific height and width in the format of the postscript output. I have attempted to specify my height and width parameters in inches as I found in the R help documentation, but this produces a graph much smaller than what it should if the standard metric is indeed inches. Since inches

Hello, If you run the following code with lattice installed: bwplot(voice.part ~ height, data=singer, xlab="Height (inches)") There will be some text in the graph e.g. Soprano 1, Soprano 2, etc - 60, 65, etc and the title: Height (Inches). How can one make the font for this text larger and/or bold? Also, is there a way to thicken or bold the lines of the box and whisker plot? Thank

Hi, I have a naive question... I have produced about 60 graphics and want to put them in one postscipt file , possibly 4 graphics on each page. I can put all of them in the same file (that's ok), but I can't find the way to put 2 or more (precisely 4, in my case) graphics on the same page (each graphics is about 6 inches (width) X 4 inches (height)). Any help would be very much

Greetings all: I have to create a graph that has very specific dimensions for publication purposes. The graph is a semilog scaled graph and the axes must range from 1 to 1,000,000 on the y axis and 0 to 100 on the x axis. The x axis should be exactly 8 inches and the y axis should be exactly 5.25 inches. I've been able to set the plot area to 8 x 5.25 using the par(pin=c(8,5.25)). The

I ran into a problem with "subset" while working at home that I am not sure is a bug or not. I defined a custom function to take a data frame of tree positions, sizes, and types (containing the columns TRT, COMP, PLOT, X, Y, DBH and CON) and wanted to make a stem map of the plot using different symbols and colors to represent the different types of tree stems. I copied a bit of the

Greetings. I'm trying to understand a problem on a Dell Laptop.

Hi Folks, This is off-topic R-wise, but it may be close to the heart of many R-users, so I think it may be the best place to ask! Users of 'gv' (the "front end" to ghostscript) will be aware of the little window which gives you the x-y coordinates (in points = 1/72 inch) of the position of the "cross-hair" mouse cursor. These coordinates are those of the corresponding

I'm trying to create a fairly basic map using R. What i want to get is the map of the country with circles representing a count of students in each state. What I've done so far is as following - map("state") symbols(data1$count,circles=log(data1$count)*3,fg=col,bg=col,add=T,inches=F) this gives me the map of the country, but one that's not populated by my counts. Does

Dear list, I have to plot some geometrical shape given as list of points. My need is the following: let's say my shape is a 1 inch large square; how can I plot it with R in a graphic format that gives me an image *exactly* 1 inch large? I tried to set oma, mar and fin parameters, but with no success. I'm currently using the xfig driver for the final images are to be included in latex
