As far as I can tell, there are no facilities in the "base" R for image analysis. Is there any extension or package for R that implements image analysis? I'm thinking of features such as o Reading and writing image files, o displaying indexed or "true color" images, o resizing, cropping, etc, of images, o filters for manipulating images (smoothing, edge detection, etc) o

Hello, I need help with a partial least square regression in R. I have read both the vignette and the post on R bloggers but it is hard to figure out how to do it. Here is the script I wrote: library(pls) plsrcue<- plsr(cue~fb+cn+n+ph+fung+bact+resp, data = cue, ncomp=7, na.action = NULL, method = "kernelpls", scale=FALSE, validation = "LOO", model = TRUE, x = FALSE, y =

Dear R community In a current paper, I'm (briefly) considering the topic of producing scatterplots or maps with point labels positioned in such a way as to minimize label overlap and occlusion. This is a topic with a large, but scattered literature. In CS, it is considered NP-hard, but there are a variety of approximate solutions. The most complete bibliography I've found is the

The help for prcomp on R 1.0.0 states that the component sdev of the return value is the eigenvalues of the cov matrix. Am I completely mistaken, or should this be the _square root_ of the eigenvalues? Also, the documentation is not very clear about how tol is used to omit components. (The _code_ is clear, though. :-) -- B/H

Hi We have just migrated our data to a new file server (more space, old server was showing its age). We have a volume for collaborative use, based on group membership. In our new server, the group write permissions are not being respected (e.g. the owner of a directory can still write to that directory but any other member of the associated group cannot, even though the directory clearly

R community: I would like to add a new title to the bibliography on the R website (http://www.r-project.org/doc/bib/R-books.html), but I cannot find instructions for doing that. Can anyone tell me, whom should I contact in order to add a new book? (I added the title to the wiki's list of books, but the bibliography and the list don't seem to be connected.) Thank you!

Sorry for the off-topic question, but I know there are some talented LaTeX users out there. Which bibliography style gives only the year in text citations (e.g "for further details, see Anderson (1992)" )?

To the R-help list, In the documentation of the prop.trend.test function in the stats package, no bibliography has been provided which would allow one to find out the theoretical basis of that function and/or details of its implementation. May I suggest that some bibliography be included, as it generally happens with other statistical functions. I currently use R 2.8.0 running on Windows XP.

Dear all, I'm a big fan and happy user of the Sweave package for routine reporting. From inside a .Rnw script, I'd like to produce the references in bibtex format for each package loaded in the environment, write them in a .bib file and load them back from the \bibliography{bibliography} statement. Is this feasible? Any help would be greatly appreciated! Thanks in advance, Paolo

Hello, I'm currently using a tool that provides a Loess fitting, but I obtained results that are slightly different from those provided by R implementation of the Loess. That's why I would like to know if you could give me a source (bibliography or web) that explains in a clear way each step of the algorithm, with the possible options to choose, etc.. in order for me to understand those

Hello to all, I'm new to R so I have a lot of problems with it, but I'll only ask the main one. I have clustered an environmental matrix with 2 different methods, and I'd like to plot them in a PCA and a db-RDA. I mean, I want see these clusters in the plots like points of differents colours, together with the rest information of the plot, but I don't know how to do this.

Hello, I'm running R2.10, Eclipse, StatEt and MikTex 2.8 to create Sweave documents, and everything seems to work great, until today... I was trying to add citations from a Bibtex file, but I just got [?] citations. However, if I open the .tex file that StatEt created in MikTex and run the latex+bibtex+pdflatex command, the citations are present. Does anyone know how to either configure

Dear All, I have these data: exampledata <- c("This is one item", "This is Another One", "And so is This") I would like to find each occurence of a blank space followed by a Capital Letter and replace it by a blank space, a left curly brace, the respective Capital Letter, and then a right curly brace. I thought the following will do: gsub(pattern = "
