similar to: Is the page number in a document created with "pdf()" accessible?

I am new to R but have used Splus for many years. When I create many graphics in sequence in Splus/Linux, each time that I complete a page, I send a message to my command line interface using the following function: FOOT <- function(PAGENO,TEXT) { mtext(outer=T, TEXT, side=1) unix("cat", c(paste("Finished with page", PAGENO)),FALSE, FALSE)

Colleagues, I am interesting in opening a PDF document via the command line from both Windows, OS X, and Linux ( R version 2.8.0). I found a command openPDF in Biobase. However, I would rather execute the command myself. For example, in OS X: > system("open filename.pdf") is successful. Is there a comparable command line command for Windows or Linux?

Colleagues, OS: OS X R: 2.10.1 I want a mu (?) to appear in text that is created using a PDF device. However, the ? does not appear as intended; instead, it is replaced by two dots. A minimal example is: > pdf("mu.pdf") > plot(1,1, type="n") > text(1,1, "\u3BC") > dev.off() The "text" command yields the following warning messages: >

R 3.4.1 OS X and Windows Colleagues I have a complicated problem that includes several components: R RTF PDF Using R (and a slew of RTF commands), I assemble a text document with an RTF extension. The document contains text, tables, and images (JPEG format, previously created with R). To ?import? the JPEG images into the document, I use the following R code: cat("\\pard\\qc

Colleagues, (R: 2.13.0; OS X) I often receive sequential datasets in which there are new rows interposed between existing rows. For example: SET1 <- data.frame(list(LETTERS=LETTERS[c(1:4, 6:10)], NUMBERS=c(1:4, 6:10))) SET2 <- data.frame(list(LETTERS=LETTERS[1:10], NUMBERS=1:10)) > SET1 LETTERS NUMBERS 1 A 1 2 B 2 3 C 3 4 D 4 5

R 2.13.1 OS X Colleagues I frequently encounter a situation in which I want to remove a single element of an array. For example, if I am reading in a bunch of CSV files, I create the list of files to be read with: LIST <- dir() However, sometimes I want to exclude one or more files. I can accomplish this with a second command: LIST <- LIST[LIST != "filename.to.be.excluded"]

R 4.0.2 OS X Colleagues Does R have the capability of adding text (e.g., page numbers) to an existing PDF (previously created with R) -- other than adding this text, the PDF should be unchanged (except for a new filename). The intent is as follows: I have multiple PDFs that I eventually merge into a single PDF, separating each one with a separator page. The content of the separator pages

Full_Name: Roger Bivand Version: 0.99.0 OS: RH Linux 6.1 Submission from: (NULL) (158.37.60.152) I am working on an interface between R and the GRASS geographical information system, written in R, with no dynamically loaded code. I have written full examples, and tested then under R 0.90.1, both by entering example() for each function and R CMD check, both of which worked without problem. Under

Colleagues Running R2.2.1 on either a Linux (RedHat 9) or Mac (10.4) platform. I created a PDF document using pdf("FILENAME.pdf", bg="transparent", version="1.4"). I then imported the graphic into PowerPoint - background was set to a non-transparent color. I was hoping that the inserted graphic would be transparent - instead, it had a white background.

R: 2.12.1 OS X Colleagues I am working with lattice graphics for the first time and I am confused by some aspects of controlling these graphics. The most pressing issue is the following: I can print the graphics without problems with the command: print(MYFUNCTION(SOMEOBJECT) However, I would like to add margin text (this terminology might not apply in this setting). I am able to do so with

Colleagues, I am using R 2.4.0 on both a Mac (10.4.8) and Linux (RedHat 9). To read data from an Excel spreadsheet, I do "save as" in Excel, then select the "Text (tab-delimited)" format. The resulting file uses a tab separator and I can usually read the file using read.delim. Sometimes, the header row contains embedded carriage returns. When I view the file,

The pdf man page contains the following text: pdf(file = ifelse(onefile, "Rplots.pdf", "Rplot%03d.pdf"), width = 6, height = 6, onefile = TRUE, family = "Helvetica", title = "R Graphics Output", fonts = NULL, version = "1.1", paper, encoding, bg, fg, pointsize) I am creating multi-page graphics in which each

OS X R 4.3.1 Colleagues I often create multipage PDFs [pdf()] in which the text "Page X" appears in the margin. These PDFs are created automatically using a massive R script. One of my clients requested that I change this to: Page X of XX where XX is the total number of pages. I don't know the number of expected pages so I can't think of any clever way to do this. I

One of the most fundamental characteristics of R programming is the use of data frames of column vectors, and one of the very first challenges I had as a then-Perl-programmer was coming to grips with the fact that unknown-length CSV files would be read completely into memory as rows and once the entire CSV was in memory it would be transposed into column vectors. I was resistant to this philosophy

Colleagues I am learning lattice graphics (R 2.12.2; OS X). Several days ago, I inquired about adding margin text to lattice graphics. Jim Price offered a useful reply, suggesting that I add: page = function(page) grid.text('words', x = 0.5, y = 0.01) to my call to the function. The entire function that he suggested was; xyplot(1 ~ 1, par.settings = list(layout.heights =

Colleagues, I am trying to read a file written by Fortran.

Colleagues R 2.8.0; OS X, Vista, Ubuntu Linux In some instances, when I create a graphic using plot(XVAR, YVAR), it would be valuable to know the values that R will display on the y-axis (e.g., if the range of data is 0-70, it might display 0, 10, 30, 50, 70). Is there a simple means to access these values? Also, in some instances, additional ticks appear between the displayed values

Would this work in general? Say I have a document with figures, special equations, text, and tables. The text and tables are relatively easy. The figures would need a conversion from pixels to lines, and the equations maybe printed out, counted as a figure, and then added to the line count. It would also be tricky if a title line was at 32 point font and the text at 12, and the more complex the

Having read all of the replies, it seems there are solutions for the question and the OP points out that some solutions such as making the document twice will affect the creation date. I suspect the additional time to do so is seconds or at most minutes so it may not be a big deal. But what about the idea of creating a PDF with a placeholder like "Page N of XXX" and after the file has

Colleagues, I am trying to create a PDF document in which I use margin text with two different fonts. The resulting text might be: XXXXXyZZZ where X and Z are one font and Y is the other. My plan was to do this in the following manner: mtext("XXXXX ZZZ", cex=2, adj=0.5, family=SOMEFONT) mtext("Y", cex=2, adj=??, family=DIFFERENTFONT) My question regards how to calculate
