I''m using standard barplot (Windows version 1.6.2 of R) to represent a certain weekly metric "v" and I would like to properly overlay on top of it its moving average "mean.8" (window of 8 weeks). I must be doing something wrong since the moving average (using "lines") doesn''t overlay properly, i.e., both x-scales do not match! ...

Can anyone tell me how to plot on the same graph two different functions (of x) using two differnt y scales (axes 2 and 4)? Thanks Nelson

Hi, How would I go about plotting all 8 columns of a data.frame on a simple line graph. i.e. eight lines and sets of points, differentiated by line pattern or colour)? An what further arguments would I need to invoke a log scale on the y-axis of that same plot (normal x-axis)? Cheers, Jeremy

I am making a plot from R indicating an average, min and max value for a number of sample types. as horizontal lines with the sample types on the y-axis. (see http://home.newmedia.no/sickel/R.html for the plot and code) In some cases, the min value is the detection limit, and I would like to indicate that bu using a <, rather than the usual | I use for indicating the value. I am plotting each

I am testing out the grid-plots, but get into a problem making a legend. I have a line plot and some points, following the model in grid.plot.and.legend() i manage to get the points correctly in the legend, but what do I do with the line? (Of cource, I can just draw a line at the right location on the plot, but I would prefer to use legend) Morten -- Morten Sickel Norwegian Radiation

Hi, I am using R a lot to make plots relating to radioactivity, I am often using expression() to label the plots with nuclide names written with superscripts, e.g. expression(paste("Releases of ", { }^{99},Tc," (TBq/year)"))->ywtext But, is there any simple way to change the number and name of the nuclide through a variable? I tried nuccode=expression({ }^{99},Tc)

I am quite new to R, so please bear over with me if I have problems with the R terminology. I want to (try to) use R for some analyses within vegetation ecology, using the vegan package. I have my data in a postgresql database, and I manage to get them into R as a dataframe with columns for respectively: Name of the analysed m2, Name of the species, coverage of species in the square in %. I

Some functions in R need quoted arguments. Consider this list: help(rm) rm(a) is.na(a) get("rm") exists("rm") Can someone explain why 'get' and 'exists' require quoted object names? Would it make sense (more consistency) to have these functions check to see if the first argument is a string, and if not, then 'substitute' it? Intuitively,

I am trying to sort a list and the data is obiously not in the right format. I am trying: x <- list() x[["A"]] <- 1 x[["B"]] <- 2 order(x) But am getting: Error in order(x) : unimplemented type 'list' in 'orderVector1' How should I change the list so that it can be sorted? What kinds of objects (classes of objects) can be sorted? Thank you. Kevin

I was looking over some of my specs. I was thinking that the following: @game.should_receive(:name).and_return(''The Battle for Blaze'') @game.should_receive(:people).and_return(5000000) @game.should_receive(:activated).and_return(true) Would it look cleaner if I could do this instead? @game.should_recieve_and_return( :name => ''The Battle for Blaze''

Hello all - I am sorry if this simple question is addressed in somewhere else. But, I couldn't find it. It's been for about a week using R. . . My problem is: Reading matrix data with "scan" does not seem to allow me to incorporate matrix labels (columns, and rows). If I use read.table, I can import the lables. But, the problem is, I don't know how I make this data as

Hello everybody! I'am just leaning Python and wanted to write something useful for me, an recursive masstagger for ogg-vorbis files.

As i understand the pyvorbis package, this is a simpe 1:1 mapping to libvorbis. dir(pyvorbins-oject) gives me an refernece to an

Hello R helpers, I would like to automate this code for many files of the same type. But I don´t know how to make it. In particular, i don´t know how to read many files each one as an r object with the name of the file. Then a for loop would be sufficient, right? Many thanks and a happy new year.
