Dear R Users, I want to exclude elements in a vector by: vector[-exclude] is it intended to cause an error if no elements are excluded? > vector <- 1:10 > exclude <- NULL > vector[-exclude] Error in -exclude or am I just definig exclude wrong, if no elements should be excluded? with kind regards, Stefan Fritsch

Hi! I got a rather stupid question (I think): Is there ANY option that makes R display numericals not like "1e-8" but as "0.00000001" by default ? And I need the outcome to be really numerical, so formatC(...) which produces a character or something like this won't be acceptable. Any help on this would be appreciated, thanx. Marc

Dear All, I am looking for the best way to use graphs from R (like xyplot, curve ...) for a presentation with powerpoint. I used to save my plot as pdf and after to copy them as image in powerpoint but the quality is not optimal by so doing. Another completely independent question is the following: when I use "main" in the xyplot, the main title is very close to my plot,

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

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

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.

Hi, In my version of R, the stats package splinefun code for fitting a Fritsch and Carlson monotonic spline does not appear to guarantee a monotonic result. If two adjoining sections both have over/undershoot the way the resulting adjustment of alpha and beta is performed can give modified values which still do not satisfy the required constraints. I do not think this is due to finite precision

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

Dear List, Is there a possibility to change the font-face for a part of the title of a plot? For example I have the following... plot(nirs, type="l", xlab="Wellenl?nge [nm]", col="darkslategray", main = "Spektrum Deschampsia caespitosa") ...and I would like to change the part of the title-string "Deschampsia caespitosa" to italics? Is

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

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

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.

Has anyone had any experience with any of the BSafe toolkits that are available and contain support for the RSA public key algorithms? I would like to use one of RSA's toolkits in a port of a Windows OpenSSH client that I am working on, in order to avoid any licensing issues from RSA. Can anyone recommend a good toolkit? I understand that there a number of them, such as BSafe SSL-C, SLPlus,

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

I need help with replacing NaN with zero (the value '0') in my dataset. The reason is that I can't get it to graph because of the NaN in the dataset. I have tried: data[is.nan(data)] <- 0 that others have suggested in the help archives but this does nothing so I am not sure what I am doing wrong. Thanks in advance for your help.
