similar to: Warnings generated by log2()/log10() are really large/takes a long time to display

Hi, I noticed some time ago that, for instance, named vectors that are really makes str() really slow when displaying the names attribute. I don't know exactly when this started, but it wasn't the case say 1-2 years ago. Example (on a WinXP 1.8GHz): > s <- 1:1000; names(s) <- s > system.time(str(s)) Named int [1:1000] 1 2 3 4 5 6 7 8 9 10 ... - attr(*, "names")=

I'm trying to troubleshoot a case where R crashes on Windows. It does not occur at all with my R v2.1.0 patched (2005-05-09), but happens on R v2.1.1 (patched or non-patched) in many different cases. The R v2.2.0dev (2005-07-15) also got this problem (although it won't crash on the below example). I previously reported this

Hi, I've got a version of rowMedians(x, na.rm=FALSE) for matrices that handles missing values implemented in C. It has been optimized for memory and speed. To avoid coercing integers to doubles, and hence allocate an additional 200% memory, there is one C function for integers and one for doubles. The rowMedians() implementation is currently sitting in my non-CRAN package R.native

Hi, help on 'mahalanobis' (in the stats package in Rv2.2.0) now says: "Description: Returns the Mahalanobis distance of all rows in 'x' and the vector mu='center' with respect to Sigma='cov'. This is (for vector 'x') defined as D^2 = (x - mu)' Sigma^{-1} (x - mu)" It does return D^2 as written. However,

I use smooth.spline(x, y) in package modreg and I would like to get value of penalized log likelihood and preferable also its two parts. To make clear what I am asking for (and make sure that I am asking for the right thing) I clarify my problem trying to use the same notation as in help(smooth.spline): I want to find the natural cubic spline f(x) such that L(f) = \sum_{k=1}{n} w[k](y[k] -

>From NEWS of R v2.6.0 devel: o R CMD check now does a recursive copy on the 'tests' directory. However, R CMD check does not run *.R scripts in such subdirectories (as I thought/hoped for), only those directly under tests/, This may or may not be intentional. If true, maybe the above should be clarified as: o R CMD check now does a recursive copy on the 'tests' directory

The VALUE section in the help for 'unlink' says: | 0| for success, |1| for failure. Not deleting a non-existent file is not a failure, nor is being unable to delete a directory if |recursive = FALSE|. However, missing values in |x| result are regarded as failures. The last phrase doesn't make sense to me. Should it be either "missing values in x are regarded as

Here are some notes/observations I've done on my setup that works for me. Hopefully it will be added to some r-forge documentation/wiki. I use: Windows Vista Business SP2 32bit TortoiseSVN 1.6.7 (Build 18415 - 32 Bit , 2010/01/22 17:55:06) PuTTY v0.60 (with Pageant v0.60) I have a deprecated r-forge project ('r-oo') that I will use through out. My r-forge username is

Does anyone know if it is possible to add a dictionary file of known words that becomes part of the *built* package to tell 'R CMD check --as-cran' not to report these words as misspelled. I want this dictionary to come with the *.tar.gz such that it will be available regardless where the package is checked. For instance, currently I get: * using log directory

To reply to Yves Gauvreau question (Jan 24, 2001) about how to set values within function, it is possible to do without without using the "<<-" assignment operator or other nasty tricks. I had the same problem and I did a nasty workaround two weeks ago implementing the functionality of reference variables, but today I "ran into" the [R] help page for ".Alias".

Full_Name: Henrik Bengtsson Version: rw1022 OS: Windows Me Submission from: (NULL) (216.175.126.55) When ${R_HOME}/share/perl/maketitle.pl tries to generate a TITLE that is longer than $lc-3 (=13) characters long, it repeats the package name on line two. Example: Now it generates an output like: com.braju.graphics com.braju.graphics Bla bla bla... But, I believe it should

Is there a way to convert between and integer and a character and vice versa? For instance i <- 65; ch <- intToChar(i); # "A" i <- charToInt(ch); # 65 or even better i <- c(65, 66); ch <- intToChar(i); # c("A", "B") i <- charToInt(ch); # c(65, 66) I have tried to do a ASCII map myself, and I figured out that the ASCII

Full_Name: Henrik Bengtsson Version: 1.3.0 OS: Windows Me Submission from: (NULL) (216.175.122.171) I realized that the title of packages in the library index when they are in a bundle is the title of the bundle and not the package. It looks like the TITLE file, which apparently is used for generating the library index, takes the value of the bundle's title and not the package's title.

I'm having a problem when generating the following LLVM intrinsics: @llvm.exp2.f32 @llvm.log2.f32 On linux, these are available on as part of standard math libraries, the code geenrator expands them into library calls, and the linker happily finds them. However, on Windows and OSX, where no implementation exists, instead of throwing a runtime error, we get a call to a function with a null

Dear R users, according the help(log), the function log2(x) should give the natural logarithm of x. I expect in case of x=2 to to get 0.6931, however, R gives me 1 as a result. Similar, logb(2,2) gives 1 again. I'm wondering if I have missed something ?

This is very minor, but shouldn't log2(quote(1:10)) throw an error,the same as log() and other math functions do? It looks like log2 and log10 evaluate a call object instead of throwing a non-numeric-argument error. They do object to non-call language objects, like expressions. > log2(quote(1:10)) [1] 0.000000 1.000000 1.584963 2.000000 2.321928 2.584963 [7] 2.807355 3.000000

Is there a way to teach xy.coords, when given log="xy", or just "x" or "y" separately, to do a decimal log10 instead of the natural log? Cheers, Alexy

Dear R users: Sorry for this simple question: I am writing a function where I would need to pickup p values and make -log10 of it. The p values are from an anova output and sometime it can yield me 0. -log10 (0) [1] Inf I can not replace Inf with 0, which not case here. This is restricting me to go further in the function and out me the error. You help is highly appreciated. Thanks; --

Dear help-list, I would like to perform a linear regression on the log10 of the two vectors ov.mag.min and res.600nm. The slope and intercept of the regression I use to plot a wider range of ov.mag.min in a double log plot. For a linear regression on only tow points, wouldn't I expect the results for two.points.min to match pretty exactly res.600nm? It does not seem to be the case here.
