I remember reading somewhere that locations on plots (in my case, arguments x and y for legend()) can be specified in several scales besides the usual data scale. I would like to set x and y as proportions of total plot size or something similar. Can anyone steer me to documentation on how to do it? -- Michael Prager, Ph.D. <Mike.Prager at noaa.gov> NOAA Center for

This is (correctly) filed under "non-reproducible." The corresponding notes say "solved by re-installing Windows (private comm)." I would like to clarify that this was solved by re-installing the patch known as "Windows 2000 Service Pack 2," not by reinstalling Windows itself. Perhaps my original message was not clear. I point this out because installing the

A minor inconvenience in updating an R installation is remembering which packages were installed previously. Has anyone written a script to inspect a previous installation, then get & install the same packages into the new installation? -- Michael Prager NOAA Center for Coastal Fisheries and Habitat Research Beaufort, North Carolina 28516 Opinions expressed are personal, not official.

To follow up on my previous question, suppose a user R session wants to unload one workspace and load another within an R session. Is the following the correct sequence? 1. save.image() to save the current workspace as .Rdata in the current working directory. 2. rm(list=ls()) to remove everything from the workspace. 3. setcwd("xxx") to set the new working directory. 4.

I probably shouldn't suggest this, because I can't volunteer to implement it. However, I bring it up in the hopes that if (1) others agree and (2) the R core group think it a good idea that a suitable volunteer will come forward. I am finding that the flood of R email messages is becoming difficult to deal with, even using filters, etc., in my email client. Would we be better

R 1.8.0 on Windows XP Professional. A huge THANK YOU to the R Team for this marvelous software. I am making lattice plots of oceanographic data. The usual layout does not conform to plotting conventions that marine scientists use when depth is the independent variable. Under those conventions, plots are made with the origin at the upper left, depth on the vertical axis (increasing as it

In working through material on p.272 of MASS (4th ed.), I came across the following model formula: pet1.lm <- lm(Y ~ No/EP - 1, Petrol) I was at a loss to understand the use of "/" until I looked in "An Introduction [!] to R," where I found the explanation. My request is that more complete material on model formulae be lifted from "Introduction to R" (or

I am using R 1.9.1 under Windows XP Professional. Is there any R function that returns the filesystem path from which the global environment (workspace) was loaded (and to which it will, by default, be saved)? This seems identical with the current directory, so in any given session it is not too difficult to find out by other means. But for several reasons I would like to find this out from

R 2.4.1 on Windows XP. Question: In traditional graphics, is it possible to find out the height of a line of text in units that can be used in arithmetic and then in calls to text()? Context: I have written a function that draws a plot and then, depending on whether some arguments are TRUE or FALSE, draws various lines of text in the plot. The text lines may be turned on or off individually

Gurus, Can I rely on the rownames() function, when applied to a matrix, always returning either NULL or an object of type character? It seems that row names can be entered as integers, but as of now (R 2.4.1 on Windows) the function returns character vectors, not numbers (which is my desired result). I am using elements of the returned vector to index the matrix. e.g., nams <-

Dear useRs, Is there a way to 'properly' format %d when plotting more than one page on png()? 'Properly' means to me with leading 0s, so that the PNGs become easy to navigate in a file/image browser. Lacking a better solution I ended up using the code below, but would much prefer something like png("test_%d.png",bg="white",width=1000,height=700) where %d

Re: placement of braces and "else" clauses. At the R prompt, I believe their placement must avoid causing a syntactically complete statement at the wrong place. This can results in what might be considered rather awkward looking code. IF it is known that code will be used via sourcing a script only, is there any potential problem with placing braces as shown below ? xxx <-

I would like to start building R packages under Windows XP. I have programming experience and a minimal but working knowlege of many Unix (-like) programming tools. The package functions (for now) will be from R source, not C or Fortran. I've installed Rtools, Perl, the MS hhc, and so on. I am setting up a command shell with the correct PATH for building packages. (The master Windows PATH

Dear Gurus, Using R 2.4.1 on Windows XP I am generating stacked barplots of age-composition of fish populations (Y) over time (X). As there are many years, not every bars is labeled. When looking at the plot, it becomes difficult to associate labels with their bars. We have improved this a bit by using axis() to add a tickmark below each bar. Can anyone suggest a way to draw ticks ONLY

I hope to use the plotmath facility to print titles that mix math and values of R variables. The help for "plotmath" has an example, which after repeated reading, I find baffling. Likewise, I have read the help file for "substitute" (wqhich seems to be needed) without ever understanding what it does, other than being used in some magic incantations. I would like to do

R 2.3.1 on Windows XP Professional. I am writing some scripts to generate examples. The Rgui menu item "File, Save to File" is helpful. Is there perhaps an equivalent R function that can be incorporated into a script? Mike Prager Southeast Fisheries Science Center, NOAA Beaufort, North Carolina USA

Dear Gurus, R 2.11.1 on Windows XP. This is a problem in interaction between R and pdftex. I need to generate a plot with both open and filled circles. It is simple enough, using pch=1 and pch=16. The R pdf graphics output is going into pdftex 1.40.10 (MikTeX 2.8). The R pdf is correct when viewed in other viewers. However, pdftex fills the open circles. I can work around this problem by

I am seeking advice about dput() and dget(). We are using the ascii format supported by these functions as a way to write data from other programs that can be read into R easily. We are able to save complicated results (in the form of an R list) to a single file that can be read trivially into R or S-Plus. My question is whether that format can be considered a safe one for medium-term (say

Windows XP. I have just updated to R 2.11.0 and then run update.packages. In the series of updates, a few will succeed, then I get a failure like package 'mvtnorm' successfully unpacked and MD5 sums checked package 'party' successfully unpacked and MD5 sums checked package 'PBSmodelling' successfully unpacked and MD5 sums checked Error in normalizePath(path) :

Some minor request for the R on Windows (2000) GUI version. I'm using 1.5.1 with the SDI interface. (1) When minimized, the main R window and the graphics window show as two copies of the same icon. That makes it less convenient to switch among tasks in Windows, as I often select the wrong one. Could they have different icons in the future, please? (2) I use a fixed-width Type 1 font
