Heja, It took me a while to find a way of implementing normal text as subscripted text in a expression followed by another expression and more subscripted text :O) It looks now as this: ylab=expression(Delta^"+"~""[paste("my subscripted text")]~">"~Delta^"+"~""[paste("my subscripted text")]) I use several par commands

posthoc tests with ANCOVA
dear all, I want to perform a posthoc test for my ANCOVA: a1<-aov(seeds~treatment*length) With summary(glht(a1, linfct = mcp(treatment = "Tukey"))) R tells me: "covariate interactions found -- please choose appropriate contrast" How do I build these contrasts? Ideally, I would like to have the posthoc test for the ANCOVA including a block-effect

vectors of different length in a matrix
HI! I?ve 3 vectors of different length (a,b,c) and want to arrange them in a matrix a,b,c as rows and the figures of these vectors in the columns (with that matrix i want to calculate a distance between thes vectors - vegan - vegdist - horn). Is there a possibilty to create such a matrix and to fill up the missing fields with NA?s automatically???? Thanx marten winter -- *Marten Winter*

transforming factor back to numbers
Hi I generate a new dataframe by doing: npl.agg <- aggregate(npl$DensPlants, list(year=npl$year, sim=npl$sim), mean, na.rm=TRUE ) Now I want to plot it by using coplot(npl.agg$x ~ npl.agg$year | npl.agg$sim, type="l") but, as npl.agg$year is seen as a factor, the order of the points on the x-axis (time axis) does not follow the numerical sorting 1...100, but rather the text

Compare linear regressios for significant differences of the slopes
Hi I have (8 measures * 96 groups) = 768 datasets for which I did linear regressions using lm(). Now I want to compare the slopes for each of the 8 measures in each of the 96 groups. As I understand , I can not use > anova(lm1, ..., lm8) as the lm1 ... lm8 are based on different datasets. I also read in previous discussions in this list, that I can see if the slope +- stddev(slope)

Combining factors
Hi I know this is a basic question and I know I have done it before but I can't find the answer any more. I have a data set, say: F1, F2, Value F1 and F2 are Factors. I would like to plot plot(TheCombinationOf(F1, F2), Value) I remember there was a function for TheCombinationOf() but I don't remember the name. I could create a new factor based on F1 and F2, but I would prefer the

combining matrices
Heja, I hope someone is still there to help me: How can I somehow merge/combine matrices to get such a result: Matrix A A B x1 1 0 x2 1 1 Matrix B C D x3 1 0 x4 0 1 Resulting Matrix? A B C D x1 1 0 0 0 x2 1 1 0 0 x3 0 0 1 0 x4 0 0 0 1 Does anyone see this probably obvious solution with R how to do this? Sorry if this question is silly...it's too hot here to think properly ;O)

Why is bubbles() creating empty png graphs?
This code below produces empty XXX.png files - if I use plot(), it works and if I enter the commands png(filename=fn) bubble(positions, do.sqrt=FALSE, main=q) dev.off() manually, it works as well. I am lost - any help appreciated. The weird thing is that it worked before I made some changes... (I don't have a copy of the working version...). R version: platform i686-pc-linux-gnu arch

exporting a table to latex
Hi I am using the latex() command from the Hmisc package to export table to latex. For formating of the values, I use the format() function. But I don't manage to get the format of the values right: I don't want scientific notation, but if I say scientific=FALSE, I get many digits after the decimal point which I can not control with digits=... and nsmall=... in the format command.
