similar to: Summary of why R has the 2^31-1 limit?

I only recently discovered options("available_packages_filters" = list(add = TRUE, "license/FOSS")) [cf. help("available.packages", package="utils") in R 2.10.0 or later] which goes nicely with my options("checkPackageLicense" = TRUE) [new in R 2.11]. But now I want to purge my library of packages I would not have installed had I known about

I can, after carefully reading about the returned values, see why library("MASS", "MASS", character.only=TRUE) has to chose between loading the package and displaying the help (I thought I had found a nice shortcut), but wouldn't the documentation be better if it said that the two are incompatible and that package= takes precedence over help=? As an aside, is there a

Must be the heat or something but I can't get my brain into gear and figure out how to get something like if (1) { c <- 1; foo <- function () print(c); } c <- 2 foo() to print 1, not 2. (The real life example is a little more complex, but you get the idea. I don't want the variable c in the function definition, I want its value at that time.) The only thing I have been

If x is a (long) vector and n << length(x), what is a fast way of finding the top-n values of x? Some suggestions (calculating the ratio of the two top values): library("rbenchmark") set.seed(1); x <- runif(1e6, max=1e7); x[1] <- NA; benchmark( replications=20, columns=c("test","elapsed"), order="elapsed" , sort = {a<-sort(x,

Hi, everyone: I forget on how to save a result from R as a word document. For example, if I run the linear regression and want to save the result: summary(lm(y~x) in a word file. So I can show it later to my clients. Any idea on how to do this? Thanks a lot, Suyan

Hello! Can you help me? How to order an data.table by values of an column?

Hello R Help, I'm working in a project with a software that register date and time data in serial time format. This format is used by excel, for exemple. In this format, 40597.3911423958 is 2011/2/23 09:23:15. First part is number os days since 1900/1/1, and second part is a fraction of a day. I need to make this transformation in R, and use it to make some algebrian operations. I found that

Hello all, a friend has a problem with tiff() which I was unable to help about. I searched the error messages to no avail. When he tries: tiff(filename = "FedeWhyDoesntThisBloodyWork.tif", width = 5, height = 5, units = "cm", bg = "white", res = 1200) Error in tiff(filename = "FedeWhyDoesntThisBloodyWork.tif", width = 5, : unable to start device

On a Unix machine I ran caret::rfe using the multicore package, and I saved the resulting object using save(lm2, file = "lm2.RData"). [Reproducible example below.] When I try to load("lm2.RData") on my Windows laptop, I get Error in loadNamespace(name) : there is no package called 'multicore' I completely understand the error and I would like to ignore it and

I have a text file that is UTF-16LE encoded with CRLF line endings and '@' as field separators that I want to read in R on a Linux system. Which would be fine as read.table("foo.txt", file.encoding = "UTF-16LE", sep = "@", ...) *except* that the data may contain the LF character which R treats as end-of-line and then barfs that there are too few elements

I want my local libraries to have priority over the system installed ones, which, as far as I can make out from help(".libPaths"), means they have to come first in that list (it doesn't actually_say_ so, but that seems to be the idea). We have R_LIBS_USER which looks made for specifying where I keep my own libraries. Unfortunately it comes last in .libPaths() [which appears to

Is there an easy way to override the compile options when installing packages from CRAN on Unix-style systems? I tried setting CFLAGS, CXXFLAGS, and FFLAGS but they are not picked up. For example (with a random package and adding -mtune only to try to get rid of the default) export CFLAGS="-march=native -mtune=native" export CXXFLAGS="-march=native -mtune=native" R CMD

What is the recommended way of requiring a certain version when loading a package (or, indeed, from R itself)? Perl has the require module version use module version require version use version constructs which is kind of what I am looking for (especially 'use' which is evaluated at compile time), but R seems to have lost the version= argument to require(). The best I have been able

I'm sure I used to be able to do my.dependencies<- c("Depends", "Imports", "LinkingTo", "Suggests", "Enhances") install.packages("animation", lib = Sys.getenv("R_LIBS_USER"), dependecies = my.dependencies) but now I get Error in download.file(url, destfile, method, mode = "wb", ...) : unused argument(s)

I'm guessing this is a FAQ but I can't find it and that it is probably not exclusive R related but relevant so I thought I'd ask: When I view the PDF output from Sweave (e.g. Example 1 from the author's web site at [1]) on a Linux system using the standard PDF viewer [2], the circles for the outliers in the plot [boxplot(Ozone ~ Month, data = airquality)] show up as the letter

Version 4.39 of the caret package was sent to CRAN. caret can be used to tune the parameters of predictive models using resampling, estimate variable importance and visualize the results. There are also various modeling and "helper" functions that can be useful for training models. caret has wrappers to over 75 different models for classification and regression. See the package

int he example below I run facter looking for the fact "sp_serial_number". as you can see, the command facter sp_serial_number returns nothing, but the fact is there and is returned when just running facter and grepping for the fact. Some fact seem to work and others do not. any ideas? marcuspro:~ allan$ facter --version 1.5.7 marcuspro:~ allan$ facter sp_serial_number marcuspro:~
