Hello, I am a beginner in R programming and recently heard about this mailing list. Currently, I am trapped into a simple problem for which I just can't find a solution. I have a huge dataset (~81,000 observations) that has been analyzed and the final result is in the form of 0 and 1(one column). I need to write a code to process this column in a little complicated way. These 81,000

Dear R-helpers, I have found a slightly annoying problem when trying to plot lines on graphs. I first created my data using tapply, thus:- y1=as.vector(fit1$coef$random$id) x1=tapply(o1,id,median,na.rm=T) x2=tapply(o2,id,median,na.rm=T) #then I plot the data, thus:- plot(x1[x2==0],y[x2==0]) #if I now try to fit the linear regression, R 'hangs up'

Hi everyone, I'm posting again, since I haven't got an answer (yet :( ). According to R help, manova does not support the inclusion of the Error() term in the formula call. I have repeated measures data for two dependent variables, so this means I can't account for subject variance in time?. Any lights? Thanks in advance, Rodrigo Abt, Department of Economic Studies, SII, Chile.

Hi All, I've been trying to make some adjustments to the graphics in a paper I wrote some time ago, for which the comments have been returned from the reviewers. I always use R for publication graphics...I think it does the best job available, for the things I am interested in. I could not get my graphics in R 181 to look the same as the old ones (completed 8 months ago), the text seemed
