function in order to plot the same graph to postscript and pdf
Hi, I've written a function in order to plot the same graph in a postcript and in a pdf file. Unfortunately, the second graph is always empty, i.e.: plot.both <- function{myplot, filename}{ pdf(file=paste(filename, ".pdf", sep="")) myplot dev.off() postscript(file=paste(filename, ".eps", sep="")) myplot dev.off() } yields in a

saving plots as objects?
Hi I had two questions regarding plots: * Is there are way to save a plot in the form of an object such that it could be displayed/modified later? * I've been using Minitab for some work and I found the burshing capability very handy (it allows me to choose a point on the graph and displays the data associated with it - x,y and other user associated data). I know that this feature is

recordPlot() on non-interactive graphics device?
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

recordPlot/replayPlot not working with saveRDS/readRDS
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

Graphics device storable in a variable
I'm using R embedded in PostgreSQL (via PL/R), and would like to use it to create images. It works fine, except that I have to create every image in a file (owned by and only readable by the PostgreSQL server), and then use PostgreSQL to read from that file and return it to the client. It would be much nicer if I could plot images into an R variable (for instance, a matrix), and return that

R: Including R plots in a Microsoft Word document
Greetings List, I am conducting some large simulations using R. As a result, I get many plots but I'm having some trouble with including some of them in a Microsoft Word document. Can any one tell me the easiest method of having copies of the R-graphs in the Word documents? Best regards Mahmoud [[alternative HTML version deleted]]

serializing recordedplot object
I use recordPlot() to save plots to disk that I render later to a variety of formats. This works fine for base R plots and ggplot2 plots, and also used to work for lattice plots. However somewhere in version 2.14 things stopped working for lattice plots. Here is an example: library(lattice); histogram(rnorm(100)); x <- recordPlot(); saveRDS(x, "myplot.rds"); y <-

Exporting R graphs
Hi, I have been a happy user of R for windows for more than a year, however, recently, I started using linux as my operating system and now I have practically switched completely. Of course, I still use R with linux, however, certain nice features of R in windows seem to be missing or hidden. I need help in basically two points: 1. In windows, I could copy the contents of a window graphic's

Advice on good programming practice, lexical scope
In "An Introduction to R" (See R help menu), there is an example of a function 'open.account' that makes use of the lexical scope in R. I have a set of functions that can be used to output R tables and graphics into a single report document. (I am aware that several tools can do this already). While reorganizing my code, I realize that I can collect my functions in a list, in

Plotting multiple curves with lattice graphs
Hi List, I would like to plot multiple curves (parametric density curves) in one plot. For example: # parameters for three normal density curves parms = data.frame(ID=c(1,2,3),mu=c(50,55,60),sigma=c(10,12,15)) # I can easily draw three normal density curves using curve(): curve(dnorm(x,mean=parms$mu[1],sd=parms$sigma[1]),from=0, to=150, ylab="density", col="red")

Exporting R graphs (review)
Hi guys, Yesterday I posted my first couple of questions (see bottom of this message) to this forum and I would like to thank you guys for all the useful feedback I got. I just would like to make some comments: 1. Exporting R graphs as vector graphics: The best answer came from Thomas Lumley <tlumley at u.washington.edu> He suggested using the RSvgDevice package.

locator() via tcltk
Hello, I'm trying to write a function using tcltk to interactively modify a plot and gather locator() data. I've read Peter's articles in Rnews, the help pages in tcltk, http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/, plus a post in R-help sometime ago, but haven't found a solution. The idea goes something like this: require(tcltk) testplot <- function() { getcoords

iterated lapply
Hi everybody, with the following code I generate a list of functions. Each function reflects a "condition". When I evaluate this list of functions by another lapply/sapply, I get an unexpected result: all values coincide. However, when I uncomment the print(), it works as expected. Is this a bug or a feature? conditions <- 1:4 test <- lapply(conditions, function(mycondition){

NA confusion (length question)
Hi folks, I am running a very simple regression using mylm <- lm(mass ~ tarsus, na.action=na.exclude) I would like the use the residuals from this analysis for more regression but I'm running into a snag when I try cbind(mylm$residuals, mydata) # where my data is the original data set The error tells me that it cannot use cbind because the length of mylm$residuals is

Subclassing lm
I'd trying to subclass the "lm" class to produce a "mylm" class whose instances behave like lm objects (are accepted by methods like summary.lm) but have additional data or slots of my own design. For starters: setClass("mylm", "lm") produces the somewhat cryptic: Warning message: Old-style (``S3'') class "mylm" supplied as a

How to concatenate expressions
Dear R-users, I am developing a plotting function, which receives expressions and character/numerical vectors as part of the many input arguments and which tries to concatenate them before displaying the result to the plot. I currently cannot find a way to make this concatenation works. I have read several posts in the list that solved this problem by pasting the different elements together
