I'm working on a big Sweave document/script on a Mac OS X system, R version 2.9.2. Under some circumstances, it appears as if Sweave is redirecting stdout, so that x <- 1; print(x) gives nothing at all. (The console is still running, as plot(x) pops up a plot as normal.) So, two questions: How do I force stdout to go back to the consol...
In R (statistical computing environment) I would like on a generic plot, with time on the x-axis, highlight some specific years. How can I bestly do this? My idea is for example a light yellow bar for the highlighted years, behind the plot of course. The plot code I have now: pdf("temperature_imfs_big_interm5.pdf", width=6, height=8);...

not only is googling R so terribly difficult, log4r has also been taken for Ruby! I am looking for the standard (if any) logging package for R. and some sample usage? I also don't see it in http://cran.r-project.org/web/packages/ (late edit: it is now at its place on CRAN and there's a R-Forge page for it.) ...

I have a data frame with two columns (data will not always be identical). 1 1 2 2 3 3 0 0 -1 -1 -2 -2 -3 -3 What I would like to do is create another column for the top 10% of the column and the bottom 10% of the column to be used as labels for a scatter plot. 1 1 2 2 3 3 1 0 0 -1 -1 -2 -2 -3 -3 2 In addition, it need...
Here is a question for R-users. I am interested in drawing a histogram with points stacked up, instead of a bar. For example if the data is (1,1,2,1,2,3,3,3,4,4), then I would like to see three points stacked up at 1, 2 points stacked up at 2 and so on. What is the best way to do this in R? ...

I am trying to output about 250 plots from an r-script and I'm receiving this error. Is there some setting that I can adjust to avoid this problem? Here is an example of how I am creating the plots: for(x in 250) { plots <- ggplot(data=dat, aes(x,y,lab=labels)) jpeg(a_paste_function) print(plots) } One thing I notice is that, whe...
What are some advantages and disadvantages to doing statistical analyses in SciPy vs. R? They seem to have been designed with opposite philosophies (plain old library vs. DSL). What are some rules of thumb about which is the right tool for the job? ...
Which conventions for naming variables and functions do you favor in R code? As far as I can tell, there are several different conventions, all of which coexist in cacophonous harmony: 1. Use of period separator, e.g. stock.prices <- c(12.01, 10.12) col.names <- c('symbol','price') Pros: Has historical precedence in the R...
With R. For a sequence of numbers x, how do I best create a function S(x, r, s) that computes sum(x[t]*x[t+r-s], t ranges from s to length(x)-r+1; r,s>0. Thanks. ...

For example in pdf(file='test.pdf', paper='letter', pagecentre=F) ### code for plot here ### dev.off() is there an option where it generate output that starts from the top of the page rather than print...
I'm now reading some books of R, but I want to know if I can use this language as I use Perl or Ruby. Things like: Image Processing File Compression Use APIs Interact With Internet But it's usual and simple(as in Perl or Ruby) to do things like this? PS: I liked this language very much, because of this I want to use it on my persona...
