Are there hashes in R? Or a package that implements hashes? I am also looking for multivariate gaussian random numbers. That brings me to: is there cholesky decomposition of a matrix?

Is there something like the LISP function dribble in R? This would log all the output to a file but still show it on the terminal too. sink just diverts the output, but I dont see a way to do...

Ugh, newbie question ... : I have a list of vectors of equal size, like list(c(1,2,3),c(4,5,6)) and want to convert this into a data frame row-wise: 1 1 4 2 2 5 3...

I wonder if there is a way to read in CSV files so that - certain fields within each record (line) are ignored, i.e. not converted to columns in the output data frame - factors/levels are created automatically: often, the...

I have the feeling that this is a dumb question but oh well ... When I have an object x with several attributes, y <- x will make a copy of x with all the attributes included. What if I just want...

I wonder which binary codings to use for the different "special" values used in R. I want to create binary coded files of double, int, and string values that should get read into R using readBin. Now, what is the...

Is it correct that there is no way of avoiding deep copying of data structures? Or asked from a different perspective, is it true that there are no pointers? :) (not that I am a fan of pointer, they just let...

I see the role of as.vector(). But even if as.vector() needs to keep its attribute-dropping side-effect for compatibility reasons, wouldn't a dropattr() still be a good idea? For instance, I can assign attributes to closures...

I though I should let you all know of this: Trying to build R-0.62.2 on a SunOS xxxx 4.1.4 2 sun4m machine using gcc (gcc version egcs-2.91.57 19980901 (egcs-1.1 release...

Thanks to all who helped on this! Of course I messed up even my first help question on R and asked the wrong question :) >From list(c(1,2,3),c(4,5,6)) I wanted a data frame with...

I am not yet shutting up on this :) Thanks for the suggestions ... problem is that the code was given as an illustration, in reality do4split would do some complicated magic calculations that yield several interesting results of mixed type. Peter...

I still dont get the "feel" of R, maybe I am thinking to complicated/LISP-damaged ... I start with a dataframe like this: df<-data.frame(a=c("x","x","y","y"),b=c(1,2,3,4)) df a...
