I'm doing: > alyL32007z <- zoo(alyL32007,alyL32007$time) > range(time(alyL32007z)) [1] "2007-01-01 00:00:00 UTC" "2007-12-31 23:30:00 UTC" But then, while the original variable is: > summary(alyL32007$NEE_st) Min. 1st Qu. Median Mean 3rd Qu. Max. NA's -15.340 -1.615 -0.054 -0.814 0.750 8.965 11124 the variable within the zoo object

Hi! Is not there an standard R function to retrieve the day of the year (since 1st Jan of the same year)? I know I can make my own using julian, but find it weird that having days(), months() etc doy() does not exist as an standard function. Also, is the following not a bit inconsistent? > a <- chron("20100506",format="ymd") > a [1] 100506 > years(a) [1] 2010

I'm trying to get a minimally intuitive way of plotting zoo objects extracted for given periods of time I do: > plot(alyL32007z$NEE_st,col=cod,type="b",pch=18,xlim=time(alyL32007z)[c(3000,15000)]) and get a correct plot but the expression for xlim is hard to read by humans. I try > time(alyL32007z)[c(3000,15000)] [1] "2007-03-04 11:30:00 UTC" "2007-11-09

I've found that while cutree() and rect.hclust() make the same classes for a given height in the dendrogram, the actual labeling of the classes is different. For example, both produce the same 4 classes but class 1 according to cutree() is class 4 according to rect.hclust(). Would it be possible that future versions provide the same labeling? rect.hclust() is useful to display the classes

I have the following time series: > class(CCasadesz2) [1] "zoo" > setmanes <- cut(time(CCasadesz2),breaks="weeks") > CCasadeswz <- aggregate(CCasadesz2,sum,by=setmanes) > class(CCasadeswz) [1] "zoo" > summary(CCasadeswz) Index CCasadeswz 2009-01-12 00:00:00: 1 Min. : 4.0 2009-01-19 00:00:00: 1 1st Qu.:

Hi! I'm finding this on MacOS Lion 10.7.5 > getOption("digits.secs") NULL > a <- "2012_10_01_14_13_32.445" > strptime(a,format="%Y_%M_%d_%H_%M_%OS") [1] "2012-02-01 14:13:32" > strptime(a,format="%Y_%M_%d_%H_%M_%OS3") [1] NA I can solve it with > options(digits.secs=3) > strptime(a,format="%Y_%M_%d_%H_%M_%OS")

Agustin, posted on R-help. I think the problem is one of the debian/ubuntu package 'r-cran-robustbase' and its setup or (missing?) dependencies. I can confirm Agustin's problem, working on Ubuntu 8.04.2 (8.04 is a "LTS" = long time support version). apt-get install r-cran-robustbase works fine, but when trying to load the package, there's a DLL - dependency on

Hi! Is there any way of having a greyed ("ghosted") text (i.e, 2006) in the background of a plot? I'm making a dynamic plot and would like to show the year of each time step as a big greyed text in the background. (the idea comes from Hans Rosling video: http://video.google.com/videoplay?docid=4237353244338529080&sourceid=searchfeed ) Thanks Agus -- Dr. Agustin Lobo Institut

Hi! Given a vector (or a factor within a df),i.e. v1 <- c(1,1,1,2,3,4,1,10,3) and a dictionary cbind(c(1,2,3),c(1001,1002,1003)) is there a function (on the same line than recode() in car) to get v2 as c(1001,1001,1001,1002,1003,4,1001,10,1003) ? I'm using myself a function based on match() since long ago (I think that thanks to advice by Prof. B. Ripley), but would like to know if there

I'm looking for a scheme to generate a default color palette for plotting points, lines and text (on a white or transparent background) with from 2 to say 9 colors with the following constraints: - "red" is reserved for another purpose - colors should be highly distinct - avoid light colors (like "yellow"s) In RColorBrewer, most of the schemes are designed for area fill

Hi! How can I subset several variables in cast? For example, I can do it for one, (ie, ph): cast(am, organismo +arriba ~ variable,subset=variable=="ph",mean,na.rm=T) For selecting ph, temperature and Ba I'm using: cast(am, organismo +arriba ~ variable,subset=variable=="ph" variable=="temperature"| variable== "Ba",mean,na.rm=T) Is there a more

Hi, all. I've been searching for a while to find out how to create an scatterplot which would let a user interact with it, specifically by hovering the mouse over a point and having a pop-up appear with data about the point. The pop-up would disappear when the mouse moved away. I've included a mock-up below. I've found out how to use identify() to make a label appear when clicking a

Hi! Is it possible to set a file to which both commands and output would get automatically saved? I've tried with sink(), but only get the output. I mean something like a combined history and sink, as you get with File/Save to File.. in the windows GUI. Tis is done with diary filename in Matlab, and you can state diary on and diary off to control what is being saved to the file. Thanks Agus

I have problems with emf files because OpenOffice does a poor job at importing figures in this format. On the other hand, imported eps figures are not displayed, just printed. Is there any R graphic gui able to export as SVG (or other vector format)? I've tried JGR, iplots and svGUI. Thanks!

Hi! I'm confused by this: > as.numeric(as.POSIXct(518400,origin="2001-01-01")) [1] 978822000 I guess the problem is that as.numeric() assumes a different origin, but cannot find any default origin. How can I get back the seconds from the POSIXct format? In other words, which the inverse function of as.POSIXct()? I've tried as.numeric and unclass() using a origin=
