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,

Dear useRs, I'm struggling again with date-related stuff: I am using R to draw water levels at certain measuring stations. My data comes as a tab-delimited text file and looks like this: DATUM P1 P2 ... 2006-11-16 425.21 423.99 2006-12-15 425.12 423.97 2007-01-16 425.16 424.06 ... (measurements started in July 2004 and still continue on a monthly or bi-weekly basis) This

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 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

Hi, Just a quick query - if I'm creating a function to produce a number of histograms per page of output (one per column from a matrix), how can I pass the column name of the matrix into the title (or indeed to form part of the x-axis label)?

Ok, I have reinstalled R-1.9.0 and this appears to have fixed the problems I was having with png(). However, I have a further question regarding png() Is it possible to pass a par() argument to the png() command? I am wanting to produce 4 plots per object, which I normally acheive on an X window by par(mfrow=c(1,4)). I have tried calling a new plot and setting par in this way but this has no

Hello, I requested help a couple of weeks ago creating a dipole field in R but receieved no responses. Eventually I opted to create a 3d sinusoidal plot and concatenate this with its inverse as a means for a "next best" situation. It seems that this isn't sufficient for my needs and I'm really after creating a continuous 3d gaussian mesh with a "positive" and

Dear R users, I am in trouble using the function solve(matrix) in a loop. When it happens that I have a singular matrix, I get an error message saying so and the loop stops. My question is if there in any way to keep on going in the loop. Thank you in advance, Laura *---------------------------------------------------------* Laura Antolini, PhD Department of

Dear R People: I used the "Surv" function to produce the following object: >a <- Surv(1:4,2:5,c(0,1,1,0)) a [1] (1,2+] (2,3 ] (3,4 ] (4,5+] >str(a) Error in "[.Surv"(object, 1:ile) : subscript out of bounds > Why does str(a) give an error, please? Or did I do something wrong? Thanks in advance. R Version 1.9.1 Windows Sincerely, Laura Holt mailto: lauraholt_983

Dear list, I just tried to use the function cluster.stat in the package fpc. I just have a couple of questions about the syntax: cluster.stats(d,clustering,alt.clustering=NULL, silhouette=TRUE,G2=FALSE,G3=FALSE) 1) the distance object (d) is an object obtained by the function dist() on my own original matrix? 2) clustering is the clusters vector as result of one of the many clustering methods?

Hello, Is there a simple way of stacking/merging two dataframes in R? I want to stack them piece-wise, not simply add one whole dataframe to the bottom of the other. I want to create as follows: x.frame: aX1 bX1 cX1 ... zX1 aX2 bX2 cX2 ... zX2 ... ... ... ... ... aX99 bX99 cX99 ... zX99 y.frame: aY1 bY1 cY1 ... zY1 aY2 bY2 cY2 ... zY2 ... ... ... ... ... aY99 bY99 cY99 ...

Hello there, I'm trying to plot vectors with p<0.1 in a NMDS ordination plot using p.max. Below the scripts I'm using.

Hi dear list, If anybody could help me, it would be great! I have two files: File 1 is a list (one column and around 100000 rows) File 2 is a list with all the names from file one and a few more (one column and more than 100000 rows) What I want is to add a column in file 2 that says which name appeared in file 1 and which doesn't (yes and no would work as a code) It's very important to

Hi, Is it possible to recreate "smoothed" data sets in R, by performing a PCA and then reconstructing a data set from say the first 2/3 EOFs? I've had a look in the help pages and don't seem to find anything relevant.

Dear all, I am using abline(lm ...) to insert a linear trendline through a portion of my data (e.g. dataset[,36:45]). However, I am finding that whilst the trendline is correctly displayed and representative of the data portion I've chosen, the line continues to run beyond this data segment and continues until it intersects the vertical axes at each side of the plot. How do I display the

Hi, I was wondering if anyone might be able to help.

I am running R 1.9.1 on SuSe9.0, and am accessing this via ssh from a Debian machine. Initially I used the command ssh -X IP.address and whilst I was able to run the model successfully the

I'm wanting to create a series of near-identical matrices via the addition of "white noise" to my starting matrix. Is there a function within R which will allow me to do this?
