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

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

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

I was wondering if there is something that can be done to improve error messages when replaying a recorded plot. For example a graphics device that is too small usually results in a helpful error message: png(height = 100) plot(1) # Error in plot.new() : figure margins too large dev.off() However when this happens when replaying a recorded plot, the error message is not so helpful. myplot

Hello R-Help, I've got a bit of an issue with WMF's. I am working on WindowsXP and outputting WMF format images. I then take the WMF format images and insert them in PowerPoint. I take the PowerPoint and convert it to PDF. The WMFs are nothing special. Just the typical x-y plot with a gray dotted grid added and a few matlines. The WMFs, when produced look great! They show

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

...if that is possible My task is to find the longest streak of continuous days a user participated in a game. Instead of writing an sql function, I chose to use the R's rle function, to get the longest streaks and then update my db table with the results. The (attached) dataframe is something like this: day user_id 2008/11/01 2001 2008/11/01 2002 2008/11/01 2003

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

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 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

Record plot which stores a plot to an internal R data structure and Replay Plot which replays the plot enables one to keep plots around and use them accross sessions at least until version 3. If you cannot restore old plots and treat them as data and save accross sessions, there is little reason for recordPlot. Either R needs to dispense with internal formats entirelly, a bad move in my opinion

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)

Hello, I'm new to this and am trying to teach myself some R by plotting biological data. The growth curve in question is supposed to be fitted to the Verhulst equation, which may be transcribed as follows: f(x)=a/(1+((a-0.008)/0.008)*exp(-(b*x))) - for a known population density (0.008) at t(0). I am trying to rework the example from "An Introduction to R" (p. 72) for my case and

Hey all, Like a lot of folks, I use rsync to pull content out to production web servers. Tastes great, less filling. Here's what I'd like to be able to do: Sometimes a web tree is not ready to sync, for whatever reason. I have many modules available, so stopping ryncd is not an option. I'd like to be able to tell rsync in daemon mode "this particular module is not available at

This looks good, except it is truncated, it should be something like 95chars long, Is your hash column set to 128 or up around there or larger?

DeaRs, i'm looking for some references on a statement as follows: "Humans are good at spotting trends and patterns in data, but they are also good at spotting those patterns where none really exist". This is not verbatim but there must be some scholarly work on this. I can't remember where I came across it - perhaps I dreamed it up? Help, anyone? Best wishes Paul -- View this
