[R] axis date format in lattice
Hello list, plotting the following example 1 in lattice only labels the x-axis with one tick mark at the beginning of February. In contrast the standard plot() function labels the x-axis with equally spaced tick marks. #example 1 --- library(lattice) date - as.Date(c(1/10/2006, 01/11/2006, 01/12/2006, 01/01/2007, 01/02/2007),format=%d/%m/%Y) xx - c(1,3,5,6,7) xx1 - as.data.frame(cbind(date, xx)) xyplot(xx~date, scales=list(x=list(format = %b))) plot(xx~date) Interestingly the behaviour in lattice only seems to arise when there is a change in calendar years. This is demonstrated by the second example with dates from within 1 calendar year only where lattice works as expected. I was wondering if the behaviour in example 1 was due to a bug or am I missing something and, more importantly, is there a way around it? #---example 2 --- date - as.Date(c(1/08/2006, 01/09/2006, 01/10/2006, 01/11/2006, 01/12/2006),format=%d/%m/%Y) xx - c(1,3,5,6,7) xx1 - as.data.frame(cbind(date, xx)) xyplot(xx~date, scales=list(x=list(format = %b))) plot(xx~date) Cheers Karl _ Dr Karl J Sommer, Department of Primary Industries, Catchment Agriculture Services, PO Box 905 Mildura, VIC, Australia 3502 Tel: +61 (0)3 5051 4390 Fax +61 (0)3 5051 4534 Email: [EMAIL PROTECTED] __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] R grahics: Save as hangs computer
Hello, thanks for the advice. I was aware that the version was out of date and your message prompted me to finally upgrade to the latest version 2.4.1. Unfortunately, running R under Emacs ESS, the problem I described earlier persists. I have also tried the Save as option under the standard RGui interface and this worked in both the old and the new versions of R, 2.3.0 and 2.4.1 respectively. The problem seems to be associated with Emacs ESS. However I don't have a clue where to start in order to find a solution. In general I quite like using Emacs ESS. It provides syntax highlighting and this makes scripts far easier to read than with the standard editor that comes with RGui. I would be grateful for any further hints from someone who has encountered similar problems in running R 2.4.1 through Emacs ESS 5.3.3 under Windows 2000.

Could you please update to the current version (2.4.1), and see if the problem persists? If so, could you please try it when running Rterm or Rgui on its own, rather than running under Emacs? Thanks.

Re: [R] R grahics: Save as hangs computer
Hello list thanks for that advice Rich. You are right a few control-G allowed me to recover and it had saved an eps file. The dev.copy2eps appears to take exactly what is visible in the graphics window and convert it to an eps file. This does the job for the moment. Opening the eps file in GSview I noticed that there is still a lot of white space in the bounding box which creates empty space when I want to include the image into a tex document. Is there a way to crop the image to remove the white space before including it in a document?

Several control-G in the *R* buffer in emacs will recover control. A second attempt in the same GUI graphics device did get the postscript file saved. A workaround for this problem is to use the command line, rather than the GUI menu, to save the file. This line dev.copy2eps() works. I discovered that it is necessary to set options(chmhelp=FALSE) when running R from emacs as the chmhelp is also freezing R and the help system. I am using R-2.4.1 on Windows. Use ?dev.copy2eps for details on the command line dev.* commands. Follow-up should go to the ess-bugs mailing list.
