Hi. How do I plot the straight line and r? in a scatter plot using a simple file x~y? Sueli Rodrigues Eng. Agr?noma - UNESP Mestranda - USP/ESALQ PPG-Solos e Nutri??o de Plantas Fones (19)93442981 (19)33719762

Hi All, I have a 1000x1000000 matrix. The calculation I would like to do is actually very simple: for each row, calculate the frequency of a given pattern. For example, a toy dataset is as follows. Col1 Col2 Col3 Col4 01 02 02 00 => Freq of ?02? is 0.5 02 02 02 01 => Freq of ?02? is 0.75 00 02 01 01 ? My code is quite simple as the following to find the pattern ?02?.

Hi I have a data.frame with dim = 18638 (rows) 6 (cols) names(dat) [1] "id" "long" "lat" "species" "type" "size" Variable "species" and "type" are factors. Species has 5 levels "BOV" "CAP" "CER" "OVI" "POR" Variable "type" has 11 levels

Thank you for help with the first part. The second part I do not understand. All I get is "3" "3". Presumably this is the factor that you refer to.

Thank you all for your help :-) Much Much Aprreciated........ I tried with the "jitter" command and it worked :-) Cheers, Latha > -----Original Message----- > From: Latha Raja > Sent: Monday, February 07, 2005 3:21 PM > To: 'r-help at stat.math.ethz.ch' > Subject: Need your help with my R plot > Importance: High > > Hi, > > I am using R to

Dear R-people: François Michonneau's method to obtain the special character plus/minus works on Windows 2000 professional. Many Thanks to François for his work!

Kia ora I'm a using lme (from nlme package) with data similar to the Orthodont dataset and am getting positive log-likelihoods (>100). This seems usual and I wondered if someone could offer a possible explanation. I can supply a sample dataset if requested, but I feel almost certain that this question has been asked and answered recently. However, I can find no trace of it in the mail

I'm new to R so forgive me if this seems like a simple question: So I have table where the row titles are string variables. When I plot the data with rows along the x-axis, the data is ordered alphabetically as opposed to the order of the table. How can I preserve the row order of the table in the plot? Thanks in advance. -- View this message in context:

Dear all, I have the following problem: I have written a function genereating to plots, eg myfunction <- (data, some.parameters) { #some calculations etc . par (mfrow=c(1,2)) plot1(......) plot2(.....) } which works fine. But for analysing several variants, I tried a slope, eg: par (mfrow=c(5,5)) for ( i in 1:10) { myfunction(data, i) } Off

Hi, I have a frame "treat" and want to find matched pairs in the data frame "control". In the matched (combined) data frame there should be two variables (0/1),indicating the "source" of the data (treat or control), so that it is possibe to set a "filter" (extraxt/select data). #Here are the dataframes (my real data frames have many variables) treat <-

Hi All, I've been having a little trouble with creating a loop that will run a a series of t.tests for inspection, Below is the code i've tried, and some checks i've looked at. I've used the get(paste()) idea as i was told previously that the use of the eval should try and be avoided. I've run a single syntax to check that my systax is correct and works without any problems

Thanks to Andy Liaw, Roger Peng, Thomas Lumley, Brian Ripley and Peter Dalgaard, all of whom addressed my questions or threads arising from them. The full messages were posted to the list so this is a brief summary: Andy Liaw explained the difference between lexical and dynamic scoping and the rationale behind the choice of lexical scoping for R. Roger Peng showed how to modify fnB. Brian

Dear List members: I'm using R1.7.1 (Windows 2000) and having difficulty with scoping. I've studied the FAQ and on-line manuals and think I have identified the source of my difficulty, but cannot work out the solution. For the purposes of illustration. I have three functions as defined below: fnA <- function(my.x) { list(first=as.character(substitute(my.x)), second=sqrt(my.x)) }

Kia ora list members: I'm having a little difficulty getting the correct standard errors from a glm.object (R 1.9.0 under Windows XP 5.1). predict() will gives standard errors of the predicted values, but I am wanting the standard errors of the mean. To clarify: Assume I have a 4x3x2 factorial with 2 complete replications (i.e. 48 observations, I've appended a dummy set of data at the
