What I'm trying to do is create best fit line in R for a set of data points and then remove all the outliers to re-create a best fit. I can't use IQR because the outliers I have in mind are easily within the range, but way out of line for the best fit, which is ruining the fit. I'd rather throw out those points all together. Thanks! [[alternative HTML version deleted]]

I have a graph of residuals and I am attempting to get a list of the indexes of each time the residual is greater than 2 standard deviations or less than -2 standard deviations, but only the first point of the section. And then I'd also need the first point where the point returns to the range between +/- 2 standard deviations. So basically if my standard deviation=1 and my residuals=c(1, 2.1,

Hello Helpers, I have some problems with fitting the model for my data... -->my Literatur says (crawley testbook)= Non-normality of errors-->I get a banana shape Q-Q plot with opening of banana downwards Structure of data: origin wt pes gender 1 wild 5.35 147.0 male 2 wild 5.90 148.0 male 3 wild 6.00 156.0 male 4 wild 7.50 157.0 male 5 wild 5.90

Hi, is there advice how to subset a data.frame, where until R version 1.7.0 it was possible to write > data[["subset"]] which meant the same as > data$subset (data is a data.frame). From 1.7.1 on this does not seem to work longer. Could there be a bug in downwards compatibility? sincerely yours Dirk

Dear r-help mailing list, this seems stupid, but I actually don't find the solution: if I have a vector of numbers x of length n, ranging, say, from -3 to 4, if I do barplot (x) all the values below 0 go downwards, and all the positive values go upward. How can I make them all begin from the minimum pointing upwards? Thanks! Gabriele Zoppoli, MD Ph.D. Fellow, Experimental and Clinical

Apologies if this is a FAQ; I couldn't find an answer on openssh.com or the mailing list archive.... Commercial SSH (I looked at 1.2.30) allocates privileged ports by counting /downwards/ from 1023, so that it will obtain a socket with (roughly speaking) the highest available privileged port number. This also appears to be the behaviour of rsh et al: (from sshconnect.c; whitespace elided)

Hey all, just upgraded to wine 1.2rc7 and am noticing an issue while playing cs1.6. I'll be playing in full screen mode when all of a sudden my regular xcursor will "pop-up" over my crosshair and intense lag starts up (FPS < ~5). It's almost as if something is competing with counterstrike for video output. Anyways, I've found that if I alt tab, then alt tab back, it fixes

I am trying to make a barplot with a broken axis using gap.barplot (in the indispensable plotrix package). This works well when the data is a vector: > twogrp<-c(rnorm(10)+4,rnorm(10)+20) > gap.barplot(twogrp,gap=c(8,16),xlab="Index",ytics=c(3,6,17,20),ylab="Group values",main="Barplot with gap") But when the data is an array (for a bar plot with multiple

I'm trying to create a new column in my data.frame where subjects are categorized depending on values on four other columns. In any other case I would just nest a few ifelse statements, however, in this case i have 4*6*2*3=144 combinations and i get weird 'context overflow' errors. So I wonder if there is a more efficient way of doing this. For illustrational purposes, let's say

Is there a colinearty function implemented in R? I have tried help.search("colinearity") and help.search("collinearity") and have searched for "colinearity" and "collinearity" on http://www.rpad.org/Rpad/Rpad-refcard.pdf but with no success. Many thanks in advance, Peter Lauren.

Hi, I have installed openSuse 11.1, which uses wine 1.1.11. I had already used wine with openSuse 10.3 which, I think, had the version 1.0. I have a dictionary for windows which doesn't work well in wine 1.1.11 but it worked with a small problem, but not so big, in 1.0. As in all dictionaries, the explanation of a word is shown in a text box. When the explanation is too long the text box

Dear R-users, When you perform "run line or selection" / "Ctrl + R" in a script window then the cursor of the script window does not go to the next line but at a place further downwards. R windows version 11 does the correct job (= goes to the next line) but version 12 does not. Is this correct ? Sincerely Elprama

I'm plotting matrices with image() and would like the axes to reflect the conventional view that the upper left corner of the plot is (1,1). But image seems to think that the lower left corner is (1,1). Can someone suggest a way of persuading it to think otherwise. In effect, I just want the y axis to run from from 1 to n downwards, not upwards. I thought that something like axes=FALSE in

Dear R users, I can get a filled triangle pointing upwards by specifying pch=17 in xyplot or lpoints, but how do I get a filled triangle that points downwards? In the standard plot function it's possible to use plot(x,y,pch=25,bg="black"), but bg= doesn't seem to work with lattice and lpoints. Thanks, Hans Gardfjell Ecology and Environmental Science Ume?

May I use "searchpaths()" with arguments partially matching file names that are found in different directories ? My question is whether this is th R function equivalent of Linux "find" or Windows "search". Both O.S. calls are given a starting point so that they search all diectories from then downwards looking for files whose names match the searching criteria.

Hello I'm trying to create a barplot with a couple of stacked positive values and with one negative value for each group. example: trees<-c(20,30,10) shrubs<-c(12,23,9) veg<-c(2,3,4) soil<-c(-100,-123,-89) example1<-t(cbind(trees,shrubs,veg)) barplot(example1) #this works so far #but now: example2<-t(cbind(trees,shrubs,veg,soil)) barplot(example2) This shows no more

Hi List, I have the following problem: I am using the multilevel package and make.univ function for available in the package and then xyplot from lattice and I want to know how could I be able to use the ?coefficient? for the straight line that passes the data ?
