I am running R 2.01 on Mac OS 10.3.7. Whenever I save graphs, they are saved as PDF files. Are there any other file formats to which I could save my graphs. I would like to directly export my graphs to MS Word, if possible. Thank you in advance.

I need to create artificial datasets with specific correlation coefficients (i.e. a dataset that returns r = 0.30, etc.) as examples for a lab I am teaching this summer. Is there a way to do that in R? Thanks.

I am attempting to fit a logistic regression plane to a 3-D scatterplot (which was generated using scatterplot3d). I've noticed that the help pages of scatterplot3d include a function titled "plane3d." However, when I attempt to use the function, I get the following message: Error: couldn't find function "plane3d" I've searched the archives and found no

Dear All, I have a rather unusual problem. I have a set of data for a class in subsurface processes. From that dataset, I must calculate the slope of the best-fit line (which is the parameter of interest). The problem I have is twofold: 1) for the purposes of the exercise, I must force my best-fit line to go through the origin (0,0), and 2) the line must be linear, even though the data is

The help file of the R bitmap function says that I have to set the environment variable R_GSCMD to the path of my Ghostscript installation. How do I set this variable (either by commandline or in R.app for Mac)? Sorry if this sounds like a very basic question, but I could not find the answer anywhere else. Many thanks Andreas -- -------------------------- Andreas Zankl, MD Division of

I have a data frame with two columns, one of which is a factor (Species) and the other is numeric (BA, which stands for basal area). Here's a sample: Species BA ACSA 55.7632696 FRAM 122.9933524 ACSA 67.54424205 ACSA 89.22123136 ACSA 82.46680716 ACSA 22.46238747 ACSA 19.94911335 ACSA 20.42035225 ACSA 19.00663555 ACSA 21.67698931 ACSA 57.80530483 ACSA 30.31636911 Dead 43.98229715 Dead

Dear R Gurus, Let's get the technical details out of the way first: Computer: 1.83 GHz MacBook R version 2.5.1 I have a data set that contains the following variables: site, species, total.vines. I need to partition the main data set by site, the further select only those species that occurred at each site. When I select by site (site.name<-subset(data frame,Site=="Site

Dear all: I have a regression model that has collinearity problems (between three regressor variables). I need a F-test that will allow me to compare between full (with all variables) and partial models (minus 1=< variables). The general F-test formula I'm using is: F = {[SS(full model) - SS(reduced model)] / (#variables taken out)} / MSS(full model) Unfortunately, the ANOVA table

I have data on number of vines per tree for ~550 trees. Over half of the trees did not have any vines and the data is fairly skewed (median = 0, mean = 1.158, 3rd qu. = 1.000). I am attempting to investigate whether plot location (four sites), species (I'm using only the four most common species), or tree dbh has a significant influence on the number of vines per tree. When I

R-users: My problem: the package fdim (which measures fractal dimensions of datasets) apparently prefers 3-D (XYZ) datasets. I'm trying to measure the information dimension (a type of fractal dimension) of a 2-D (XY) dataset. Here's some examples of the preferred 3-D data (XYZ): library(fdim) XYZ <- (makehplane(NumN=300, DimM=3, Longit=300)) fdim(XYZ,q=0.999999,PlotF=TRUE)

R gurus, I'm working on data analysis for a small project. My response variable is total vines per tree (median = 0, mean = 1.65, min = 0, max = 24). My predictors are two categorical variables (four sites and four species) and one continuous (tree diameter at breast height (DBH)). The main question I'm attempting to answer is whether or not the species identity of a tree has

Dear List, I am using the bioconductor package Category to do some gene enrichment analysis, and usually save my KEGGmnplot's using a dev2bitmap command. This has worked just fine, until suddenly earlier today I got this error-message: > dev2bitmap("04610_080721.jpg",type="jpeg", height = 10, width = 10, res = 200) Error in dev2bitmap("04610_CSF080721.jpg",

R gurus, I have a data set that looks something like this: Site Species DBH #Vines G PLOC 45.9 4 G ACNE 23.3 1 G ACNE 12.0 0 G FRAM 35.9 5 G AEGL 11.2 2 N PLOC 77.3 12 N JUNI 78.6 7 N ACNE 18.9 1 N ACNE 15.7 3 N ACRU 35.5 4 H ACSA2 24.1 6 H ULAM 35.2 7 There are 730 individual trees (22 species) from four sites in the actual data set. I would like to create a second data frame that

Hi, in help("R_GSCMD") it says "R_GSCMD: Optional. The path to Ghostscript, used by dev2bitmap, bitmap and embedFonts. Consulted when those functions are invoked.". However, if 'R_GSCMD' contains a full pathname to the Ghostscript executable (as above "path" indicates), e.g. > Sys.getenv("R_GSCMD") [1] "C:\\Program

Hi Folks: I'm writing a little package that may not ever hit CRAN or even be distributed beyond a relatively narrow audience at my company. Nevertheless, I have tried to adhere to practices that would work if it were. With that in mind, I have read the Writing R Extensions Manual (and my humble kudos to its writers, as it has successfully guided even an ignoramus like myself ) and Luke

I would like to plot two different samples on the same scatterplot in R using different symbols for the different groups. Could someone please let me know how this can be done? Thank you very much.

Hello, I'm planning to start using R. Before getting into it, I'd like to ask a couple of questions. Does R carry out loglinear model analysis? That is, will it provide the chi-squared goodness of fit test statistic for a given hierarchical loglinear model? Maybe even do a model selection procedure (like Brown's two-step procedure, or forward/backward selection)? Thanks

Hello, Could someone please tell me why the following doesn't work: I have a file C:\Program Files\R\rw1051\etc\Renviron.site, which contains the line: R_LIBS= "C:/Jim/LocalR-Libraries/FromCran"; "C:/Jim/LocalR-Libraries/Cantata" >From the documentation, I gather that I have put this file in the default location, but to be safe I also explicitly set the R_ENVIRON

Dear helpers, I'm trying out the embedFonts() to embed fonts into my pdf files. However, when I inspect the new pdf with a program designed to look for embedded fonts, I see that the fonts have in fact not been embedded. Below are my calls.
