...or of this graph. I also would like to manipulate the linetypes and colors of the lines. I've read the documentation, but it was not clear to me, how to do this. Are there other plotting functions in R, which can do the same? Erich ________________________________________________ Erich Studerus Lic. Phil.

Dear R-users, In a randomized placebo-controlled within-subject design, subjects recieved a psycho-active drug and placebo. Subjects filled out a questionnaire containing 15 scales on four different time points after drug administration. In order to detect drug effects on each time point, I compared scale values between placebo and drug for all time conditions and scales, which sums up to

Hi I have a dataframe in which some subjects appear in more than one row. I want to extract the subject-rows which have the minimum date per subject. I tried the following aggregate function. attach(dataframe.xy) aggregate(Date,list(SubjectID),min) Unfortunately, the format of the Date-column changes to numeric, when I'm applying this function. How can I preserve the date format? Thanks

Sorry, for asking the same question again, but I got no reactions the last time. Maybe it was just overseen by the experts. I'm using the xtable function with Sweave and Lyx and I would like to know how to get automatic line breaks for long strings in a column of the table. I've learned from the Lyx wiki that the Latex command \linebreak produces table cells with multiple lines. I tried to

Hi, I have the following problem with ggplot2: When I specify black contours for bars in a barplot, ggplot automatically shows diagonal lines in the legend boxes. Is there a way, to remove these diagonal lines? Here's a simple example: library(ggplot2) df<-data.frame(x=gl(6,1),y=rnorm(6,100,50)) ggplot(df,aes(y=y,x=x,fill=x))+geom_bar(aes(group=x),colour='black',size=1)+

Hello I would like to pass a model formula as an argument to the with.mids function from the mice package. The with.mids functon fits models to multiply imputed data sets. Here's a simple example library(mice) #Create multiple imputations on the nhanes data contained in the mice package. imp <- mice(nahnes) #Fitting a linear model with each imputed data set the regular way works

Hi, I have a set of 30 binary variables measuring side effects after drug treatment. Since each subject can have multiple side effects, I want to display these side effects in a multiple choice table. I'm using the summary and mChoice functions of the Hmisc package, because it produces nicely formatted latex tables. My problem is, that table includes a category for people who have at

Hello Because I want to use different true type fonts with latex, I''m using the XeTeX typesetting engine for my sweave-documents. I''m using Lyx with Sweave on a Windows 7 PC and have set up LyX to work with XeTeX according to the following instructions: http://wiki.lyx.org/LyX/XeTeX Because the input file for XeTeX is assumed to be in UTF-8 encoding, I set the encoding

Hi, I'm having several problems with the Hmisc latex function. First, there seems to be a conflict between the cellTexCmds and the cgroupTexComds. When I'm using both at the same time, I get an error message. Here's an example. I just added cellTexComds to the example on page 10 of this document: http://biostat.mc.vanderbilt.edu/twiki/pub/Main/StatReport/latexFineControl.pdf x

Hi, I'm using the xtable function with Sweave and Lyx. The table that I'd like to display has very long string characters in one column. Is there a way to get automatic line breaks for the strings in that column with xtable? Thanks for your help! Erich

Dear R-Users, I'm trying to set up a repeated measures anova with two within subjects factors. I tried it by 3 different anova functions: aov, Anova (from car package) and lme (from nlme package). I managed to get the same results with aov and Anova, but the results that I get from lme are slightly different and I don't figure out why. I guess I did not set up the error structure
