Hello, R-Help - I am trying to plot the results of an ordination from package vegan. The tricky part for me right now is getting the colors of the ellipses denoting the 95% confidence intervals of the group centroids to match the colors of the points for those same groups. >From and earlier post, I saw the code to make a plot of the ordination using different colors for my different groups.

Greetings Everyone - I have a data frame "x" that looks like this: v1 v2 1 A 1 B 1 B 2 B 2 W 2 W 3 D 3 D 3 Z What I would like to do is create a new data frame, "y", that has one row for each unique value of v1, and returns the corresponding mode of v2. If I were to run it on the above data frame, it should therefore return: v1 v2 1

Hello R Help! I would like to make a legible boxplot of tree growth rates for each of seven tree species at each of seven different sites. It's a lot of data to put on one figure, I know. I made a beautiful, interpretable figure using color, but my target journal can't deal with color figures. I can use seven shades of grey to fill the boxes, but the figure then becomes uninterpretable -

Since the number of choices is small (6), how about this? Starting with Jeff's initial DFM: DFM <- structure(list(obs = 1:6, start = structure(c(16467, 14710, 13152, 13787, 15126, 12696), class = "Date"), end = structure(c(17167, 14975, 13636, 13879, 15340, 12753), class = "Date"), D = c(700, 265, 484, 92, 214, 57), bin = structure(c(6L, 3L, 5L, 1L, 3L, 1L), .Label

Thank you Jeff and All, Within a given time period (say 700 days, from the start day), I am expecting measurements taken at each time interval;. In this case "0" means measurement taken, "1" not taken (stopped or opted out and " -1" don't consider that time period for that individual. This will be compared with the actual measurements taken (Observed-

I am trying to apply methods used by Chaloupka & Limpus (1997) ( http://www.int-res.com/articles/meps/146/m146p001.pdf) to my own turtle growth data. I am having trouble with two things... 1) After the GAM is fit, the residuals are skewed. >m1 <- gam(growth~s(mean.size, bs="cr")+s(year,bs="cr",k=7)+s(cohort,bs="cr")+s(age,bs="cr"), data=grow,

I would like to create a subtotal table with custom bands. seq1 = seq(0, 100, by = 5) seq2 = seq(100, 1000, by = 100) Bands = c(seq1, seq2) #Prices Prices = sample(1:1000, 200, replace=F) #corresponding size for the given price above. size = sample(1:1000, 200, replace=F) How would I find the subtotal of the size based on a given price falls within a band? -- View this message in

Hello I am very new to R.  I have an R task to complete that I have not been able to find a straightforward answer to as of yet.  I have a list of values. I would like to count the number of values that are in one bin, the number that fall in the next bin, etc. For example My input file is:  123 48 342 442 43 232 32 129 191 147 I would like the output to be similar to:  0-100 3 100-200 4

Hi, Not sure where to submit this to so I'll try here. Below is the toneset for Iceland. Hopefully this can be added into the asterisk package. [is] description = Iceland ringcadence = 1000,4000 dial = 425 busy = 425/250,0/250 ring = 425/1000,0/5000 congestion = 425+250/250,0/250 callwaiting = 600/100,0/100,600/100,0/9000 record = 1400/500,0/15000 info = !950/330,!1400/330,!1800/330,0

Hi to all if someone of you is interested on it, i've changed the code of app_asr.c With these patch you can use the ASR application to play DTMF tones, so you can have your own AGI application that uses the ASR and manages the DTMF tones without change the dialplan.

When using drag and drop, the browser window will not scroll if you move the mouse off the page. This makes it very difficult, if not impossible to create certain types of web applications. I know this has been mentioned before and is on the Wish List, but it''s very frustrating. If you look at this other Javascript library called "Drag''nDrop & DHTML Library"

Hello there, I have two groups (men and women) and I know per group how many of them smoke or don't smoke (women 40 of 200; men 100 of 300). I would like to know how I can compare in R if men and women differ significantly in their smoking. However, because there are more men in the sample than women I cannot just compare the number of smokers and non-smokers in both groups, right?! (I would

Dear R users, I used R to draw many histograms and I would like to automatically save them into a jpeg file. I tried the following code since I know .ps file could be saved like this way: postscript("AYA_ELA.jpeg",horizontal=F,onefile=T) ......#some funtions inside here dev.off() There was a jpeg file, however, there is no pictures inside. Any suggestion? Thanks. Rebecca

Hello R-helpers! I have a question concerning extracting sequence information from a vector. I have a vector (representing the bins of a time series where the frequency of occurrences is greater than some threshold) where I would like to extract the min, median and max of each group of consecutive numbers. For Example: tmp <- c(24,25,29,35,36,37,38,39,40,41,42,43,44,45,46,47,68,69,70,71) I

Hey there, I apologize if this is an irritatingly simple question ... I'm a new user. I can't understand why R flips the sign of all data values when reading in external text files (tab delimited or csv) with the read.delim or read.csv functions. The signs of data values also seem to be flipped after assigning a new data.frame from within R (xnew <-- edit(data.frame()). What am

Hi, I want to automate a set of scripts that spit out data that are later used by R to plot graphs. However, I need to get into R's environment now and then use my R script using the source command. Is there a way to run the R script from the unix prompt ?. Thanks, Krishnan. ----------------------------------------------------------- Sivaramakrishna Iyer Krishnan (Anand) Research Assistant
