[R] bootstrapping data.frame and matrix

Dear All, When bootstrapping a statistics based on more than one vector, from a data.frame or a matrix object, it looks like I am not able to pass the data to R. What am I doing wrong? I use the library bootstrap. Here is an example with a data.frame called data boot2_bootstrap(data, theta,

[R] Missing 'getGroupMembers()'

Hi, I'm trying to write a method such that my own classes can be used with the groups like Summary and Math, but when I tried to look for examples or just wanted to get an idea of which functions are the members of a group, I found out that the function getGroupMembers is not present... I

[R] Normal deviate generation - Marsaglia's ziggurat method

Hi: I was wondering why Marsaglia's new ziggurat method for generating deviates from the standard normal distribution has not been implemented in the R base package. I know that it is available in SuppDists pacakage of Bob Wheeler, as rziggurat. According my timing tests, it is about 6 to 7

Do you want to write S3 or S4 methods for these groups? Both systems have groups with those names (and they are not the same). In either case, the details are in ?.Methods (in current versions of R). On Fri, 30 May 2003, Anton Crombach wrote: I'm trying to write a method such that my own

S4 methods, I'm using Programming with data (~ the green book) as my main reference for programming. Not everything is the same in R, usually that was not a problem, but using these groups I got a bit lost. I've been looking in the R docs of ?setGenerics, ?setGeneric and so on already. Do you

Re: [R] Normal deviate generation - Marsaglia's ziggurat method

Accuracy and reliability are more important than speed. As you say, it is available elsewhere, but who actually needs a faster method? 1 million normals take 0.55s on my machine (an Athlon 2600): 1 million uniforms take 0.16s, so there is not I think scope to be `6 to 7 times faster' at R level.

Since it is available in the `SuppDists' package, why do we need it in the `base' package? There are perhaps hundreds of useful functions that exist in external packages that are not in `base'. My understanding was that one goal was to keep `base' from getting too bloated. -roger Ravi
