Full_Name: Volker Franz Version: Version 1.6.2 (2003-01-10) OS: Debian Submission from: (NULL) (192.124.28.104) Hi there, it seems to me that data.ellipse of package "car" (Version 1.0-1) produces confidence interval's which are too big. To see this, do: library(car) plot(c(-2,2),c(-2,2),pch=0) data.ellipse(rnorm(10000),rnorm(10000),levels=0.68,plot.points=F) abline(v=+1)

Hi, I'm using the R library(car) to draw confidence/prediction ellipses in a scatterplot. >From what i understood the ellipse() function return an ellipse based parameters: shape, center, radius . If i read dataEllipse() function i can see how these parameters are calculated for a confidence ellipse. ibrary(car) a=c(12,12,4,5,63,63,23) b=c(13,15,7,10,73,83,43) v <-

Dear all, I generated a Correlograms and used the panel.ellipse (confidence ellipse and smoothed line) option. Is there a way to get instead of the smoothed line the linear regression?

Hi folks, I'd like to use scatter3d (which is in R commander) to plot more than one dataset in the same graph, each dataset with a different color. The kind of stuff you would do with "holdon" in Matlab. I read a recent message that was posted to this list with a similar problem, but I couldn't understand the reply. Could someone give me one example? How do you plot subgroups

... or if I understand correctly, simply expression(frac(additive ~ HCO[3]^"-", true ~ HCO[3]^"-" ))) Cheers, Bert On Fri, Feb 2, 2024 at 3:06?AM Rui Barradas <ruipbarradas at sapo.pt> wrote: > ?s 10:01 de 02/02/2024, Troels Ring escreveu: > > Hi friends - I'm plotting a ratio of bicarbonates i ggplot2 and > > > >

Hi friends - I'm plotting a ratio of bicarbonates i ggplot2 and ylab(expression(paste(frac("additive BIC","true BIC")))) worked OK - but now I have been asked to put the chemistry instead - so I wrote ?ylab(expression(paste(frac("additive",HCO[3]^"-","true",HCO[3]^"-")))) - and frac saw that as additive = numerator and HCO3- =

Dear R-devel, I've made some potential extensions to writeForeignSAS in 'foreign' that I wanted to pass along if anyone is interested. I've attached the diff -u output against the version found in foreign_0.8-15 and an .R file with my changes. (In this .R file, the function is named writeForeignSAS7 to simplify testing/comparisons.) I've tried to alter the current

Hello, I want to create 10 dataframe using a for loop. I don t know what to do to create 10 different dataframes whose name is parametrized with variable i. This syntaxe fails.

here appears to be a bug in the foreign library. The following code used to work, but now generates an error when 'package="SAS"' is specified: ds <- read.csv("http://www.math.smith.edu/sasr/datasets/help.csv") # running foreign package version 0.8-30 library(foreign) # this works fine write.foreign(ds, "foo", "bar", package="Stata") #

I tried to use write.foreign() to export to SAS this morning and got an error. When I looked at the code for writeForeignSAS() I saw this line: dfn < -df which I think should be dfn <- df So, I tried to run update.packages() to see if there was an updated version and got the following result. > update.packages(c("foreign")) Warning message: In list.files(lib) :

Hola, estoy buscando la manera de crear una lista que contenga una serie de data frames (un número que puede variar con el tiempo pero que siempre van a tener un nombre con una pauta definida). La lista debe estar nombrada con el nombre de cada data frame. Quiero evitar esto: # ------- lista <- list(df1 = df1, df2 = df2, dfn = dfn) # ------- ya que como no sé cuantos data frames voy a tener

Hi, Attached is both the patch and a gzipped version of the patch that is the fix for bug 8141 - rewriting substituteList in coerce.c to use a loop instead of recursion to walk the list. The new version passes all of my tests (make check-all, etc) and I have used it with no negative impact to my work (as verified by comparing before and after tests) so far. The new version fixes the

Just giving the survey package a spin... I'm accustomed to stata, and it seems very similar in many respects. One thing is throwing me, however. I've gotten my data in, and specified the design. Looks like the weighting is right (based on published population estimates from these data), but now I'd like to check my "marginal means" for proportions against those that have

Hello. Douglas Bates has explained in a previous posting to R why he does not output residual degrees of freedom, F values and probabilities in the mixed model (lmer) function: because the usual degrees of freedom (obs - fixed df -1) are not exact and are really only upper bounds. I am interpreting what he said but I am not a professional statistician, so I might be getting this wrong... Does
