I don't understand the 'order' function
I thought I've understood the 'order' function, using simple examples like:
order(c(5,4,-2))
[1] 3 2 1
However, I arrived to the following example:
order(c(2465, 2255, 2085, 1545, 1335, 1210, 920, 210, 210, 505, 1045))
[1] 8 9 10 7 11 6 5 4 3 2 1
and I was completely perplexed!
Shouldn't the output vector be 11 10 9 8 7 6 4 1 2 3 5 ?
Do I have a damaged

Using assign with mapply
I have a data frame whose first colum contains the names of the variables
and whose second colum contains the values to assign to them:
: kkk <- data.frame(vars=c("var1", "var2", "var3"),
vals=c(10, 20, 30), stringsAsFactors=F)
If I do
: assign(kkk$vars[1], kkk$vals[1])
it works

Named components in a list
I'm studying lists and I came to an example where
> L
$name
[1] "Fred"
$wife
[1] "Mary"
$no.children
[1] 4
$child.ages
[1] 4 7 9
then following the instructions to extend the list with a new component, I
executed:
> L[5] <-list(NewName="something")
and the new list I got was:
> L
$name
[1] "Fred"
$wife

Passing function to tapply as a string
Hi,
Was wondering if it is possible to pass function name as a parameter, smth
along this line
param.to.pass<-c(1,'max','h')
dd<-function(dfd, param=param.to.pass,...){
ttime.int <- format(ttime,fmt)

A kind of set operation in R
I have an ordered "set" of numbers, represented by a vector, say
> X <- c(10:13, 17,18)
> X
[1] 10 11 12 13 17 18
then I have a "sub-set" of X, say
> Y <- c(11,12,17,18)
Is there a simple way in R to have a logical vector (parallel to X) indicating
what elements of X are in Y, i.e.,

Trying to understand factors
I'm trying to figure out about factors, however the on-line documentation is
rather sparse. I guess, factors are intended for grouping arrays members into
categories, which R names "Levels". And so we have:

Interacting with the Operating System
Is there any way to issue operating system commands and geting back the results,
in R?
I mean, for instance, in Linux, to execute from R the 'ls' command and getting
back a list of files in the current directory, or, equivalently, in Windows/DOS,
the 'dir' command?
I'm not interested in the 'ls' or 'dir' commands it is just an example.

Coercing of types when raising a number to a series of powers
I'm trying to produce a series of powers of a number as follows:
|> 0.05^0:5
[1] 1 2 3 4 5
This is not the result I expected. I guess some kind of coercion happened,
since,
|> class(0.05^0:5)
[1] "integer"
Could anyone explain me what is happening here?
Thanks,

Trying to use pipes in R
Hi,
I'm trying to use pipes in R. By now, I could launch the linux command "wc"
(to count words from a text), but
I don't know how to capture the results, say in a vector of chars...
Here is the R code I'm trying:
:> f <- pipe("wc", open="w")
:> writeLines(c("uno dos tres", "cuatro cinco", "seis"), f)
:> close(f)
