Hi there, I got a piece of code for the Iris data which allows to display correlation coefficients for each Iris species in the lower panel (color coded). I would now like to add e.g. a "*" to show the significance of each correlation next to the correlation coefficient. Furthermore I would like to make a t.test between the species "setosa" and "versicolor" for

I was hoping that there might be some way to attach significance code like the ones from summary.lm to a dataframe. Anyone know how to do something like that. Here is the function i'd like to add that functionality to: add1.coef <- function(model,scope,test="F",p.value=1,order.by.p=FALSE) { num <- length(model$coefficients) add <- add1(model,scope,test=test) sub <-

Okay, I stumped. I'm trying to build a matrix or data.frame that consists of values by group. For example, resid, group 574 0.536196370873122 E 575 0.93191093696265 E 576 -1.27116094894117 A 577 -1.05159666055027 A 578 0.398273458301184 D 579 0.586373126102573 E 580 0.806575304513802 E 581 0.897258393118338 E 582 0.342393324256838 D 583 0.781245511773227 E I

Hi there! In my case, cor(d[1:20]) makes me a good correlation matrix. Now I'd like to have it one sided, means only the left bottom side to be printed (the others are the same) and I'd like to have * where the p-value is lower than 0.05 and ** lower than 0.01. How can I do this? And another thing: Is there a way to output that table as a latex table? Thanks, Martin -- Ihr

Hi, I apologize if the solution is right in front of me, but I can't find anything on how to convert a class of 'noquote' to 'matrix'. I've tried as.matrix and I've tried coercing it by 'class(x)<-matrix', but of course that didn't work. I've been using the function 'symnum' which returns an object of class 'noquote'. Here is an

Hi all, Does anyone know a way to change the significant stars in mtable (package memisc)? The default is Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1, however I need it to be Signif. codes: 0 '***' 0.01 '**' 0.05 '*' 0.1 ' ' 1 Kind regards, Erich [[alternative HTML version deleted]]

Hey Everyone, I'm pretty new at R and wanted to try and make some graphs with dummy data before using it to analyze my own. I successfully made a bar graph and error bars, but I can't figure out how to align them properly (currently they are not centered on the bars and some of them aren't even close). Here's the code that I'm using: > marks <- sample(4:10, size=50,

R-folks, Is there a function, like aggregate, that allows users to bin values? I've got to break down a data frame into classes of 5cm (or something like it), and I only know how to do it using code like, signif <- symnum( stems$dbh, corr = FALSE, na = FALSE, cutpoints = c(0,10,20,30,40,999), symbols = c(0,10,20,30,40) )

Hello, I'd like to add custom labels to my pair() plot. These labels include math expression but they aren't correctly displayed... Further, I want that the boxes for the text.panel (diagonal) have an other background color (grey80). Is that generally possible? If yes how do I have to set it? What I've so far is: panel.cor <- function(x, y, digits=2, prefix="",

I've trying to check for model bias. It was recommended to me that I should break the residuals into n groups and test to see if the mean is different from zero. What is the best way to generate the groups. I've generated a matrix that contains the residuals and groups, but the values all have quotes around them. 1) how do I get rid of the quotes? 2) is this an acceptable method for

Hello, a probably rather stupid question to which I can't find an answer: I have a bar chart, and I want to present which bars are significantly different by placing a line with an asterisk above then (similarly to fig. 3 in: http://jnm.snmjournals.org/content/46/4/574.figures-only). Does anyone have a reference where can I find some instructions how to learn this? Thanks a lot! Omer --

Hi list. I was saving my modified pairs graphic using a custom panel from the R Graphics site, and I got an interesting difference in the final image when I save it as eps or png. This custom panel make possible to show at the left side of the pairs plot the p-value as symbol and the correlation r value with its cex proportional to the r value itself. Well, when saving as a png file

Dear r-help users, I am using Sweave and Latex to create tables with output from several statistical test. As an example: I have a grouping variable "group" with two levels ("x" and "y") which I compare on variables ("a" and "b"). I have created a table in which means, standard deviations, and the statistic and p.value resulting from a t.test is

Hi im trying to add error bars to my barplots, there very basic, i have a few grapghs where the y variable is different but on all the X variable is Age (Adult and Juvenile) however this is split into two levels so i have males and females, so my graph basically has four bars on it. I know how to add eror bars for instance when there is only one level eg lookng at the diffrence between male and

I am new to R. I want to graph group data using a "Traditional Bar Chart with Standard Error Bar", like the kind shown here: http://samiam.colorado.edu/~mcclella/ftep/twoGroups/twoGroupGraphs.html Is there a simple way to do this? So far, I have only figured out how to plot the bars using barplot. testdata <- scan(, list(group=0,xbar=0,se=0)) 400 0.36038 0.02154 200 0.35927

Hi all, This is probably a very simple question but I cannot figure out how to do it. I run the fourthcorner method with my data and would like to adjust the p values for multiple comparisons using Holm correction. When I run the fourthcorner I obtain the results in yellow. What do I need to do to be able to aply the Holm correction to those p values? > library(ade4) > four1 <-
