I want to use grid to modify some boxplots made using ggplot. I would really appreciate if somebody could guide me to a resource on how to use grid to modify such graphics. I guess the basic approach will be similar to using grid to modify lattice graphics. To that extent something that explains use of grid to modify lattice graphics may also be useful. I have gone through vignettes in the grid

And in that case, where can I find it? Grid is part of R, hence you can look at R's NEWS, e.g. at <https://cran.r-project.org/doc/manuals/r-devel/NEWS.html> or directly in the svn

Hi I have put up some web pages containing a number of plots (and diagrams) produced using R (they correspond to the figures for a book that I am working on about R graphics), with the relevant R code provided for each plot (or diagram), at http://www.stat.auckland.ac.nz/~paul/RGraphics/rgraphics.html Hope these are of some help/use; comments/suggestions welcome.

Hello, I would like to plot my data in a fashion similar to a boxplot, but plot the true data points without a box, just overlay lines of the summary generated by the boxplot. I have less than 10 observations within each group, so I think showing the actual data would be more effective than the box of the boxplot. I have been unable to find a way to do this. Here is example data: >

Dear list, I'm puzzled by the graphical output in the following example, library(grid) foo <- function(){ grid.rect(gp=gpar(fill="black")) print(get.gpar()$fill) grid.rect(width=0.2,height=0.2) } png("test.png", bg = "transparent") foo() dev.off() png("test1.png", bg = "white") foo() dev.off() It seems that the default value of

My aim is to create a figure consisting of three maps: Alaska in the upper left corner, the 48 contiguous US states in the center right, and Hawaii in the lower left corner. In some ways the figure I'm trying to create is analogous to figure 1.5 in Paul Murrell's excellent "R Graphics", which combines a map of New Zealand with a map of the world. I tried adapting the code

Dear HelpeRs, I have a script where I save several thousands of graphics. These are then used in Latex through Sweave. Unfortunately R crashes while making these plots and Windows pops up some message that I run low on virtual memory. I tried to save the plots using pdf(), windows() and postscript() and also tried to run it with R CMD BATCH myscript.R. But after a while R slows down and crashes

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

Dear R-users, after seeking for help in R-search I did not find any hint on my particular problem. Countless help on "true" overlay, but nothing on this. Please consider the following: par(mfrow = c(2, 1)) T <- seq(0, 20, by = 0.01) ## PLOT 1 plot(T, 30*exp(-0.65*T), type = "l" ) points(T, 30*exp(-0.26 * T), type = "l", lty = "F8") points(T,

Hello! Don't quite understand how can I delete grobs and simultaneously erase graphic output they produce. I first change grob's "vp" field to null (grid.edit(gr,vp=NULL)) to erase it and then call rm(gr) (as grobs are external pointers I'm not shure what this method actually frees allocated memory). May be there is simpler method? Does garbage collector have any effect

Hello ! There is something quite simple I want to do with R but I found nowhere in the help how to do it. I just want to plot data which are in a matrix, every column being a data set and having the same x-axis (just an index). So for example if I have a 50 x 6 matrix I want 6 set of points on the same plot. I tried plot,new() plot(MATRIX[,1]) plot(MATRIX[,2]) ... but it replaces the previous
