Hi, The following function works, but is there a neater way to write it? f = function(x,...) { # return a character vector of the arguments passed in after 'x' gsub(" ","",unlist(strsplit(deparse(substitute(list(...))),"[(,)]")))[-1] } > f(x,a,b,c*d) [1] "a" "b" "c*d" > Thanks. [[alternative HTML

Dear all, I?m having trouble getting a list of regression variables back into a dataframe. mydf <- data.frame(x1=rnorm(100), x2=rnorm(100), x3=rnorm(100)) mydf$fac<-factor(sample((0:2),replace=T,100)) mydf$y<- mydf$x1+0.01+mydf$x2*3-mydf$x3*19+rnorm(100) dlply(mydf,.(fac),function(df) lm(y~x1+x2+x3,data=df))->dl here I?d like to use ldply(dl,coef(summary)) or something

Under the "further resources" section I'd like to suggest the following addition : * http://crantastic.org/ lists popular packages according to other users votes. Consider briefly reviewing the top 30 packages before posting to r-help since someone may have already released a package that solves your problem. Thats just a straw man idea so I hope there will be answer, or

Hello, Regarding this in R-devel/NEWS/New features : o ?library(pkg)? no longer warns about a conflict with a function from ?package:base? if the function is an identical copy of the base one but with a different environment. Why would one want an identical copy in a different environment? I'm thinking I may be missing out on a trick here. Matthew

Looking at shash in unique.c, from R-2.10.1 I'm wondering if it makes sense to hash the pointer itself rather than the string it points to? In other words could the SEXP pointer be cast to unsigned int and the usual scatter be called on that as if it were integer? shash would look like a slightly modified version of ihash like this : static int shash(SEXP x, int indx, HashData *d) {

Hi, In the example below why is d 10 times bigger than m, according to object.size ? It also takes around 10 times as long to create, which fits with object.size() being truthful. gcinfo(TRUE) also indicates a great deal more garbage collector activity caused by data.frame() than matrix(). $ R --vanilla .... > nr = 1000000 > system.time(m<<-matrix(integer(1), nrow=nr, ncol=2)) [1]

Hi, Have I missed something, or misunderstood? The r-help posting guide asks users to contact the package maintainer : "If the question relates to a contributed package, e.g., one downloaded from CRAN, try contacting the package maintainer first.

Is it intended that the first suffix can no longer be blank?

Hi, n = 10000000 L = list(a=integer(n), b=integer(n)) L[[2]][1:10] gives me the first 10 items of the 2nd vector in the list L. It works fine. However it appears to copy the entire L[[2]] vector in memory first, before subsetting it. It seems reasonable that "[[" can't know that all that is to be done is to do [1:10] on the result and therefore a copy in memory of the entire
