Dear R help list I have recently started using R to visualize time series of water level measurements. The code I wrote does exactly what I want: plot(x, a$B112, axes=FALSE, ylim=c(405,410), col="red", pch=15, type="o", ylab="metres above sea level", main="Main Plot Title") axis(2, at=405:410, tck=1, col="gray60") axis.Date(1,

Instead of x<-seq(as.Date("2004-01-01"), as.Date("2008-06-01"),by="month") from=iso2chron("2004-01-01") to= iso2chron("2008-06-01") from <-chron2UTCsecs(from) to<-chron2UTCsecs(to) delta##how many secs i.e month time in secs xx <- seq(from=from, to=to, by=delta) x <- UTCsecs2chron(xx) I think it will works

Hi, I am trying to download the new version of R from Bristol University (the UK mirror). However when I have down loaded the files and am trying to 'run' them to install the software but Windows is telling me that the files are corrupted and to 'obtain a new version of the programme'. I need R for a piece of my MSc course work so would really appreciate any help or ideas.

Hi John I had the same problem: signed onto the list, then got flooded by too many emails. So I changed my personal settings to the digest mode (see link below). That means that once a day I get *ONE* email which summarizes the help list email traffic of that day. Then I can fly through its index to see what's going on. There's even an option to turn off delivery of mails from the help

Eric Recordé un ejemplo rápido ## Setup up coordinate system (with x == y aspect ratio): plot(c(-2,3), c(-1,5), type = "n", xlab = "x", ylab = "y", asp = 1) ## the x- and y-axis, and an integer grid abline(h = 0, v = 0, col = "gray60") text(1,0, "abline( h = 0 )", col = "gray60", adj = c(0, -.1)) abline(h = -1:5, v = -2:3, col =

Hi, I am R beginner and am trying to figure out how to generate a complete list of species for every point, visit, and year. The code below is close but does not give me a list of species for every point, visit, and year in my data set. spplist<-unique(sumPtCt$Species) spplength<-length(spplist) Pointlist<-unique(sumPtCt$Point) Pointlength<-length(Pointlist)

Hi, I try to create a vertical line in my plot, which has a xaxis comprising time formated data. This is what I tried: ---------------- y<-152833 x<-strptime(y, format="%H%M%S") abline(v=x, col="red") ---------------- for some reason, it doesn't work and no error msg is displayed... I hope someone can tell me what I do wrong, or maybe an alternative. Thanks

Estimado Eric En Hmisc la función labcurve puede ser útil, en todos casos crear una curva con valores constantes, habría que intentar, pero labcurve en algunos ejemplos en mi computadora no anda. Ayer envié dos correos, el primero era de latticeextra, usted nombra lattice, pero podría funcionar, en latticeextra: ## horizontal and vertical lines xyplot(ysim ~ xsim) + layer(panel.ablineq(v

Hi, I am trying to identify duplicate values in a column in a date frame. The duplicated function identifies the duplicate rows in the data frame but it only does this for the second record, not both records. Is there a way to mark both rows in the data frame as TRUE? dfA$dups<-duplicated(dfA$Value) dfA Site State Value dups 929 VA 73 FALSE 929 VA 73 TRUE 930 VA 76 FALSE 930 VA 76 TRUE 931

Estimados, tengo un grafico al que agregue una linea con abline(), este es el codigo ... library(Hmisc) # agregar una linea horizontal con el valor del angulo de contacto del control trellis.device(color = FALSE) xYplot(Cbind(ca.med[,3],ca.med[,5],ca.med[,6])~ca.med[,2], groups=Sol, data=ca.med, xlab=list(label="Concentration (mM)", cex=1.3), ylab=list(label="Contact Angle

Full_Name: Hsiu-Khuern Tang Version: 1.8.0 OS: GNU/Linux (Debian unstable) Submission from: (NULL) (156.153.255.243) Hi, I use palette(rgb(red=..., green=..., blue=..., names=mycolors)) to define my own color palette. After doing this, the names `mycolors' are not stored in palette() anymore, so that palette() returns a mix of built-in color names and RGB values. Eg: > palette()

Hi all, I'm trying to figure out a way to create a data graphic that I haven't ever seen an example of before, but hopefully there's an R package out there for it. The idea is to essentially create a heatmap, but to allow each column and/or row to be a different width, rather than having uniform column and row height. This is sort of like a Marimekko chart in appearance, except that

Hi all, I'm trying to plot this two curves in a single cartesian plane, but when I plot the first one, the plot appears with no negative "y" value. When I plot the second curve, it almost does not apear in the graph. I was trying the plot.window but with no success. Can someone help me with this? If possible, I'd like to plot this curves in a perfect cartesian plane. f =

I would like to organize my data as follows: I have a table that contains various data, and the numbers represent a level of similarity between these data, eg RF00013 has 100% similarity with the data RF00014. I would leave my table as a heatmap where darker colors represent higher similarity, and the lighter colors represent less level of similarity. I'm using version 2.11 of R. these

Hi, I am interested in ggplot2 and I found this lattice code very interesting (http://addictedtor.free.fr/graphiques/graphcode.php?graph=48). Code: library(lattice) lattice.options(default.theme = canonical.theme(color = FALSE)) tmp <- expand.grid(geology = c("Sand","Clay","Silt","Rock"), species = c("ArisDiff",

Hello! I apologize - I never used lattice before, so my question is probably very basic - but I just can't find the answer in the archive nor in the documentation: I have a named numeric vector p of 6 numbers (of the type 6 numbers with people's names to whom those numbers belong). I want a simple bar chart. I am doing: library(lattice) trellis.par.set(fontsize=list(text=12)) #

Hey folks, I''m off to Vietnam for a week on my way home to Australia so I''ll be off the list for a while. Don''t think I''m ignoring you. When I get back I intend to aggressively hunt down the segfault problem that some of you are having in Ferret so that problem will soon be ancient history. If anyone can narrow down a test case that can consistently segfault it
