Hi all, I am plotting a financial time series, but I need a more detailed X-Axis. Example: x <- zoo(rnorm(1:6000), as.Date("1992-11-11")+c(1:6000)) plot(x) The X-Axis is labeled "1995", "2000" and "2005". I would need either "1995", "1997", etc. or maybe yearly I used google first, then look at "?plot.zoo" but

Hello all, I used google and looked at the documentation to find out why the ADONIS function is called adonis (in the vegan package). I am writing a document and would like to include a abbreviation list (similar to "ANOSIM = Analysis of Similarities"). regards, Steve

Dear List, Is it possible to have function names like ? (unicode universal quantifier)? This question is inspired by agda source code, which supports this. http://www.cs.nott.ac.uk/~nad/listings/lib-0.4/Algebra.html It would be handy to use. My guess is, however, that it's not supportet in R. Regards, Steve

Dear list, in short: I would like to calculate the mean frequency of a signal (e.g. time series) using the wavelet transform. with details: I did not find a R function to calculate a mean frequency using one of the cran packages. My searches using R Site Search returned: **(1)waveclock {waveclock} R Documentation Reconstruction of the modal frequencies in a time series using continuous

I'm interested in using R's plotting capabilities to try to generate a graph showing the relationship/pairing frequency of words appearing in a block of unstructured text. I don't have a specific algorithm or approach in mind, just looking to portray text in an interesting fashion. The output I'm hoping for is something like the following called a "Phrase Network":

Dear List-Members, I am plotting a barplot with the lattice package. The code works, but when I execute the same code in a for-loop no plot is shown. Can't figure what the problem is. (Maybe I am missing something here, but I tried it with plot device pdf, calling windows() or X11(), testing on windows and linux, etc.) INFO: R version 2.9.1 (2009-06-26) using Windows/RGui require(lattice)

Dear List, I just googled to find out if notched box plots are possible with ggplot2, but couldn't find a answer to it. boxplot() has the option: notch = TRUE, e.g.: boxplot(mpg$hwy, notch=TRUE) My example code (taken from the net) is: require(ggplot2) qplot(class, hwy, fill=factor(year), data=mpg, geom="boxplot", position="dodge")+theme_bw() Thank you for you help!

I imagine I make a function whose results are a Matrix Z How cn I save in a txt or excel file the result of apply my function? something similar to save Z.txt. Thanks in advance. [[alternative HTML version deleted]]

Dear List, R ist somtimes a bit frustrating... I ran the example from http://bm2.genes.nig.ac.jp/RGM2/R_current/library/QRMlib/man/plotMultiTS.html and I get an error. Has someone an explanation for this? Thanks a lot, Steve CODE: library(R.utils) library(tseries) library(wmtsa) library(waveslim) library(brainwaver) library(timeSeries) library(QRMlib) > ?plotMultiTS >
