Re: [R] graphical parameters: margins
Prof Brian Ripley[EMAIL PROTECTED] 3/1/2007 09:22 In this particular case 'An Introduction to R' has a comprehensive description of graphical parameters with figures (as do all good books on S/R e.g. MASS4 - since it has the same first author). Thanks, Brian, I've reached both Introduction to R, particularly http://cran.r-project.org/doc/manuals/R-intro.html#Figure-margins, and MASS4 at Springer website. I think it is worth I ask the Three Wise Men for MASS4 as a present!

[R] graphical parameters: margins
Hi all, Please, while using image() which is the graphical parameter which control the space between ylab and the y axis? I do need to write a number of relatively long y labels and I am not able the control, if possible, this space. See the effect I need to avoid... http://nvx.environmentalchange.net/@rrodriguez/images/overlapping.jpg Thanks for your help, Ricardo -- Ricardo Rodríguez Your XEN ICT Team __ 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] graphical parameters: margins
-- Ricardo Rodríguez Your XEN ICT Team Gavin Simpson[EMAIL PROTECTED] 2/1/2007 17:44 Either of these two gives you the answer help.search(graphical parameters) RSiteSearch(graphical parameters margin) more specifically, read ?par and in particular, the entry for parameter 'mar' and it's relatives. You might also need to add the axis label separately from the figure: opar - par(mar = c(5,7,4,2) +0.1) plot(1:10, ann = FALSE) # or plot(1:10, ylab = ) mtext(label, side = 2, line = 6) par(opar) 1) opar - par(mar = c(5,7,4,2) +0.1) creates 7.1 lines on the left of the plot and saves defaults 2) mtext(label, side = 2, line = 6) displays the axis label on line 6 to push it away from the plot axis. Repeat for other sides... 3) par(opar) resets to the defaults. HTH Thanks Gavin, I frequently reach the help page or any other document concerning the doubt, but at least for me it is by no means easy to correctly interpret their contents without the help of more experienced people. I do hope I will catch up ASAP!

Re: [R] tabulate: switching columns and rows
hadley wickham[EMAIL PROTECTED] 31/12/2006 19:33 Hi Ricardo, You might want to have a look at the reshape package, http://had.co.nz/reshape, which provides a more general and flexible framework for reshaping data in R. The version of warpbreaks I have doesn't have the replicate variable, so unfortunately I can't provide you with example code for this case. However, you should be able to figure it out for your data using the documentation available on the website. Thanks, Hadley, My fault: I've not provided the line concerning replicate variable. It is included in ?xtabs: warpbreaks$replicate - rep(1:9, len = 54) It will be great to have an example with these given data. Anyway, I will have a look to reshape at the given site. Thanks a lot!

Re: [R] barplot - how to force vertical axis to cover entire plot area
Hi, Etienne, I've seen this while working with barplot and never been able to understand the general rule, but by setting ylim high enough, I've always been able to draw a y axis covering the biggest values. Could you send a data subset to reproduce the issue? Thanks. Best, Ricardo -- Ricardo Rodríguez Your XEN ICT Team Etienne[EMAIL PROTECTED] 7/12/2006 01:43 I'm using barplot with the following call: barplot(stat_data[[5]][,],axes=TRUE,axisnames=TRUE,axis.lty=1,xlab=xlab,ylab=ylab,beside=TRUE,las=1,font.lab=2,font.axis=1,legend.text=TRUE) On some data, the vertical axis does not cover the whole plot area and the last tick mark is smaller than the maximum value. I tried setting the ylim values but even with that, some plots are still not OK, it just shrinks the length of the bars. Attached is a png example of the problem. I hope it gets through.

Re: [R] axis in an image () plot
jim holtman[EMAIL PROTECTED] 24/11/2006 23:21 If you data is a matrix, then try: image(1:5, 1:14, data.rect) text(row(data.rect), col(data.rect), data.rect) Thanks, Jim. It works great and perfectly fill my requirements. I better understand now how text() works. By the way, there is a line at the bottom of your message reading What is the problem you are trying to solve?, is this a kind of motto or are you asking me what I am trying to solve? :-) Thanks!

Re: [R] axis in an image () plot
Jim Lemon[EMAIL PROTECTED] 26/11/2006 12:05 Hi Ricardo, This might be what you want (say your data frame is called my.df): library(plotrix) color2D.matplot(my.df,c(1,0),c(0,0),c(0,1)) text(rep(0.5:13.5,5),rep(seq(4.5,0.5,by=-1),14), unlist(my.df),col=white) and in fact it looks so neat that I might add it as an option. Jim Thanks, Jim! Once the original problem was solved by using image(), your plotrix() package is of major interest to keep improving this kind of graphics!

[R] axis in an image() plot
Hi all, I've found quite usefull colored-grid created by image() but I'm facing a doubt I am not able to solve. Given the following data rectangle... 1 2 3 4 5 6 7 8 9 10 11 12 13 14 1 12 22 0 7 2 1 0 2 0 2 6 -3 0 3 2 0 -1 0 9 3 -4 0 0 0 0 3 0 0 0 3 29 45 6 12 16 85 -2 0 -3 -4 89 -1 -1 1 4 2 9 3 6 17 3 -2 -9 -2 8 -1 0 0 0 5 44 16 -3 21 23 3 2 1 0 -2 13 18 -5 2 I am not able to draw x and y axis labeled 1 to 14 and 1 to 5 by 1. I've tried a number of options by using axis() to no avail. It will be also very helpfull to be able to draw the value of each x,y combination within its position in the grid. Text() seems to be the answer, but I am not able yet to get the correct position for each label. Please, could you point me in the right direction or offer some example?
