R had an internal Plot format which could be saved in files and then reused. Just like one can save data.frames or lists of data which I routinely do could save plot which could be used for further elaboration and analysis. Thus you could modify a plot after you saved it. Matlab has a fig format which it uses for that purpose. The current version of R version 3 allows plots only to be used

The documentation for recordPlot says the following: > As of R 3.3.0, it is possible (again) to replay a plot from another R session using, for example, saveRDS and readRDS. However, I haven't been able to save and restore a plot displaylist and have it work within the same R session, using R 3.4.3 or 3.3.3. Here's an example: # Save displaylist for a simple plot

I have plots that were stored using recordPlot() in a fairly recent but pre-1.6.0 version of R that will not replayPlot() in R 1.6.0. The error message is Error in replayPlot(x) : invalid hex digit in color or lty The plots were stored in June (2002-6-14), each as an element of a list named 'rpl'. The version of R that was current then is what I used. At that time I was able to

Hey all, I've run accross what seems to be a bug in the recordPlot/replayPlot functionality (or at least the lack of a feature which seems pretty reasonable to expect to be there) When drawing to a file-based graphics device (I tested with png()), the file resulting from calling replayPlot on a recordedplot object does not contain an identical image to that captured by the same graphics

Hi What you are doing "wrong" is loading a recordedplot into the same session that it was created in. The saveRDS()/readRDS() works if you save in one R session and then read in a different R session. The assumption is that if you are still in the same session that created the recordedplot you still have the recordedplot (e.g., you can just do replayPlot(r) instead of

Hi. Q. Is there a way to record a plot using grDevices::recordPlot() without opening an interactive (=visible GUI window) graphics device (not even for a flash of a second)? Related: help("recordPlot", package="grDevices") says: "These functions record and replay the displaylist of the current graphics device." Is the intention that recordPlot() should be able to

I am trying to save plots that I create using calls to windows() folowed by multiple calls to plot to place several plots on a page. I want to store the plots as variables to be able to recall them later. The documentation states: "Recorded plot histories are of class "SavedPlots". They have a print method, and a subset method. As the individual plots are of class

Hello, first, I'd like to congratulate the core team to the new R version 1.1. I think it's a great update, with glimpses into an even greater future (tcltk!). While playing around with the new functions (on Win 95), I found the following: As the documentation states, when I generate a plot and save it with recordPlot, I can regenerate it by printing the variable: > plot(1:10) >

I wrote about this some time back as this new "feature" has made R less convenient for me since I story many, say 1000 to 1500 diagnostic plots per session. Georgely Daroczi has a nice hack in Rapporter//pander which it makes it possible to replay a single bad plot by hacking the data structure so as to change an offending part. Not surprisingl.doing this to all my saved recordedplot

I want to do a zoom with recordPlot(). I have problems with lists. (R-2.0.1 patched 2004-11-30 , various linux). I have problems with RecordPlot class structure. > plot(1:10) > saveP <- recordPlot() > dev.off() > sx <- saveP[[1]][[2]][[2]] > saveP[[1]][[2]][[2]] <- sx Error in "[[<-"(`*tmp*`, 1, value = list(list( .Primitive("plot.new")),

I have trouble understanding the R list object and how to add objects and get them out. I''m trying to collect snapshots with recordPlot and replay them. Got great help from everybody here yesterday on my histogram function, works fine to make the pictures: histomatic <- function (s1,s2,s3,var){ if (is.numeric (s2[[var]])) { par(mfrow=c(3,1)); rz <- range(s1[[var]],

Hi, I wonder if this is expected or I'm doing a wrong thing. pdf() dev.control('enable') library("grid") plot(1) grid.text("A") res = recordPlot() dev.off() cairo_pdf() replayPlot(res) dev.off() *** caught segfault *** address 0x4, cause 'memory not mapped' > sessionInfo() R version 3.3.2 (2016-10-31) Platform: x86_64-apple-darwin13.4.0 (64-bit)

Hi This appears to be happening (at least) because cairo_pdf() delays initialising a Cairo surface until BM_NewPage(), rather than initiliasing a Cairo surface in BM_Open(), and replayPlot() triggers some activity (set clip region) on the device BEFORE a new page is started (so the pointer to the Cairo surface is null, so BOOM). Not sure yet whether to blame replayPlot() for not starting

I think this is pretty certainly a bug, so I'm cc'ing this to r-bugs. -p Kaspar Pflugshaupt <pflugshaupt@geobot.umnw.ethz.ch> writes: > Hello, > > first, I'd like to congratulate the core team to the new R version 1.1.

Hello, I am plotting data as a venn diagram but would like to be able to control how it is plotted like a lattice object. Right now, it plots right away. I would like to name it and then plot at will. I thought to convert the whole thing to a PostScript file then get it back into R via grImport, but surely (please!) there must be a less roundabout way to do this. Any help is appreciated. Here

Hi You could also look at dev.capture(), depending on which screen device you are using.

I realize the R developers are probably overwhelmed and have little time for this, but the documentation really needs some serious reorganizaton. A good through description of basic variable types would help a lot, e.g. the difference between lists, arrays, matrices and frames. And, it appears there is some object-orientation to R, but it is not complete. I can't, for instance find a

Sorry for newbie question, but i havent find the way to resize existing graphics window from r console. Of course, i can do it by dragging window borders and i can set up size of the device (window) if i call windows(width,height) but is it really impossible to resize existing window?? how i can do this? i am using R 1.6.0 on Microsoft Windows 2000 OS Thanks for your help
