[R] warning in library(GRASS)
Hi, With your help I've found out that library(GRASS) is the responsible for several warnings I'm obtaining. I've got a loop (~100 runs) and for every loop, I'm carrying out several operations over a sequence of raster maps (12) read from the GRASS GIS. But for every map and loop I always use RGRASS.temp as the R-workspace name for the imported raster files, no matter the name of the source GRASS raster map, e.g; RGRASS.temp - rast.get(G,rlist=paste(A2.grassname,it,.Bmaxind.,ib,sep=),catlabels=FALSE) As I always overwrite the same R object, I should hope that the number of calls to rast.get would have no influence on a warning like Too many open raster files, which I'm getting after the fourth loop. Am I missinterpreting something about the way R objects are stored, and every call to rast.get generates a new internal copy of RGRASS.temp? If so, is there a way to solve this problem? Thanks again and best wishes, Javier -- Javier García-Pintado Institute of Earth Sciences Jaume Almera (CSIC) Lluis Sole Sabaris s/n, 08028 Barcelona Phone: +34 934095410 Fax: +34 934110012 e-mail:[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.

[R] chron() question
Hi all, I'm using chron and it seems to me that there is a strange behaviour when constructing chronological objects. An extract of my source data is: tdr.hhmm[4860:4870] [1] 22:22:00 22:42:00 23:02:00 23:22:00 23:42:00 00:02:00 [7] 00:22:00 00:42:00 01:02:00 01:22:00 01:42:00 tdr.dat$year[4860:4870] [1] 2005 2005 2005 2005 2005 2006 2006 2006 2006 2006 2006 tdr.dat$day[4860:4870] [1] 365 365 365 365 365 1 1 1 1 1 1 And if I use: tdr.chron - chron(dates.=tdr.dat$day,times.=tdr.hhmm,origin.=c(month=1,day=0,year=tdr.dat$year),format=c(dates=d/m/y,times=h:m:s)) The result is: tdr.chron[4860:4870] [1] (31/12/05 22:22:00) (31/12/05 22:42:00) (31/12/05 23:02:00) [4] (31/12/05 23:22:00) (31/12/05 23:42:00) (01/01/05 00:02:00) [7] (01/01/05 00:22:00) (01/01/05 00:42:00) (01/01/05 01:02:00) [10] (01/01/05 01:22:00) (01/01/05 01:42:00) While it seems to me that, through the R recycling rule, it should consider the year 2006 in the corresponding results.

[R] help with this indexing
Hi all,
Let's say I have a long data frame and a short one, both with three
colums: $east, $north, $value
And I need to fill in the short$value, extracting the corresponding
value from long$value, for coinciding $east and $north in both tables.
I know the possibility:
for (i in 1:length(short$value)){
short$value[i] - long$value[long$east==short$east
long$north==short$north]
}
How could I avoid this loop?
Thanks and regards,
Javier

[R] gstat package. singular attibute
Hello, I'm using the gstat package within R for an automated procedure that uses ordinary kriging. I can see that there is a logical (singular) atrtibute of some adjusted model semivariograms: .- attr(*, singular)= logi TRUE I cannot find documentation about the exact meaning and the implications of this attribute, and I dont know anything about the inner calculations of model semivariograms. I guess that the inverse of some matrix need to be calculated , and this matrix is singular, but I also see that the model semivariogram is calculated anyway. Could you briefly tell me something about the significance of this attribute and if I should not use these model semivariograms when the singular attibute is true?

Re: [R] expression()
Thanks you,
this works right.
I just would like to note one thing:
although I've found italic() in the help for plotmath and I can see that
the italic function:
mtext(expression(italic(beta)[max]),side=1,line=2)
does not work on the greek beta character.
Though not strictly necessary, this would be perfect for my plots, as I
use them for papers to be published.
Wishes,
Javier

[R] which() over a matrix

[R] interacting with X11() device
Hello;
I'm preparing a simple function that plots sequentially a number of time
series for visual inspection, after some previous transformations.
To allow the user to have time to see the series I'm using
Sys.sleep(1.5) between calls to line(). But is it possible to add some
mechanism that would allow the user, for example with one click on the
plotting device, to pause the sequential plotting for a more detailed
inspection of a specific series and with another click to go on with the
sequential display?
Without the details, it is something like this:
results.plot - function(i){
plot(...)
for (j in i){
lines(j)
Sys.time(1.5)
}
}
And I'm calling the function for all series in a matrix: results.plot(1:100)
Thanks and best regards,
Javier

[R] tcltk error when calling a dialog
Hello;
I've got several radiobuttons in tcltk with the following sintaxis:
tk2.rd - /tkradiobutton(/frame4,command=plotDialog1,text=New Q plot,
value=2, variable=OUTPLOTtclVar/)/
All the buttons call the same function plotDialog1. With the objective
of call a dialog to select some plotting options.
When I select one of the radiobuttons and the windows with the plotting
options appears. It appears blank, and I obtain this message of error in R:
Error in structure(.External(dotTclObjv, objv, PACKAGE = tcltk),
class = tclObj) :
[tcl] grab failed: window not viewable.
All radio buttons are within a frame in a window named dlg. I've
removed nearly everything in this function and I still obtain the same
error when clicking on a radiobutton.
Even with this very simple remaining code:
plotDialog1 - function/()/ {
mddlg2 - /tktoplevel()/
tkwm./deiconify(/mddlg2/)/
tkgrab./set(/mddlg2/)/
tkwm./title(/mddlg2,Plot options/)/
onNO - function/()/
{
tkgrab./release(/mddlg2/)/
/tkdestroy(/mddlg2/)/
/tkfocus(/dlg/)/
}
// NO.but - /tkbutton(/mddlg2,text= Cancel ,command=onNO/)/
/tkgrid(/NO.but,pady=2/)/
/tkfocus(/mddlg2/)/
tkwait./window(/mddlg2/)/
}
Please for those who are used to utilize the tcltk library: ¿Can you see a
clear error in this?
I'm new to this library and tcltk and I'm unable to find out the error.
Thanks and best regards,
Javier

Re: [R] R script autoload at startup
Thank you very much Prof Brian R, I also wonder how I missed that. Anyway, In my .Rprofile file: .First - function() cat (\n Welcome to R!\n) works perfectly, while: .First - function() winMenuAdd(Newmenu) give me the answer: Error in .First(): couldn't find function winMenuAdd I just can add the new menu, and create the menu entries later, calling a source() that adds the menus. Perhaps the functions to add menus to the RGUI are called after the .RProfile is red? To add it via the .Rprofile would be perfect, but anywat, to be able to create the menu calling manually a source after the GUI is completely started is good enough for me. Best regards, Javier El Viernes, 24 de Febrero de 2006 21:12, escribió: See ?Startup for how to do this via .Rprofile or etc/Rprofile.site.

Now I don't receive the message anymore and it cannot find BWidgets under R.
