Summary statistics across factor levels
R users,
I intention is to calculate some summary statistics across factor
levels. I know that in Hmisc package there is a summary function which
produces neat summary statistics when using "cross" option. I would
like to produce similar output with N and Missing columns but produce
a data.frame. Is there any built-in function for that?

Data separated by spaces, getting data into R using field lengths
I have a text file similar to this (separated by spaces):
x <- "DF12 This is an example 1 This
DF12 This is an 1232 This is
DF14 This is 12334 This is an
DF15 This 23 This is an example
"
and I know the field lengths of each variable (there is 5 variables in
this data set), which are:
varlength <- c(2, 2, 18, 5, 18)
How can I import this kind of data into R, using the varlength

How to export tables in list separately using write.table or sink?
R users,
My intention is to take factors out of DF, create list of tables and
export these tables separately using write.table or sink function.
write.table writes tables out as DF:s, should I use sink instead?
Here is my example:
a <- data.frame( indx = 1:20,
var1 = rep(c("I20", "I40", "A50", "B60"), each=5),

How to get names of a list into df:s?
R users,
I have a simple lapply question.
g <- list(a=1:3, b=4:6, c=7:9)
g <- lapply(g, function(x) as.data.frame(x))
lapply(g, function(x) cbind(x, var1 = rep(names(g), each=nrow(x))[1:nrow(x)]))
I get
$a
x var1
1 1 a
2 2 a
3 3 a
$b
x var1
1 4 a
2 5 a
3 6 a
$c
x var1
1 7 a
2 8 a
3 9 a
And I would like to have
$a
x var1
1 1 a
2 2 a

Random sequence of days?
Dear list,
I tried to find a solution for this problem from the archives but
couldn't find any. I would like sample sequence of ten days from
vector d
d <- seq(as.Date("2007-02-12"), as.Date("2008-08-18"), by="days")
so that the days follow each other (sample(d, 10) is not the
appropriate solution). Any ideas?
Best regards,

Ceiling to the nearest ten?
R-users,
Is there a function for ceiling to the nearest ten?
a <- 1:10*4
a
[1] 4 8 12 16 20 24 28 32 36 40
The resulting vector should look like this ("ceiling to the nearest ten")
[1] 10 10 20 20 20 30 30 40 40 40
Thanks in advance

plot legend: combining filled boxes and lines
Hello,
I have difficulties combining boxes and lines in plot legend. I
searched previous R-posts and found this (with no solution):

Simple programming question
Hi R-users,
I have a simple question for R heavy users. If I have a data frame like this
dfr <- data.frame(id=1:16, categ=rep(LETTERS[1:4], 4),
var3=c(8,7,6,6,5,4,5,4,3,4,3,2,3,2,1,1))
dfr <- dfr[order(dfr$categ),]
and I want to score values or points in variable named "var3" following this
kind of logic:

Following this post http://tolstoy.newcastle.edu.au/R/help/06/06/28965.html ,
how do I get last two rows (or six or ten) by id group out of the data
frame? Here the example gives just the last row.

I have a vector of dates

Find missing days
Hi,
I have a data.frame like this:
y <- rnorm(60)
lev <- gl(3,20, labels=paste("lev", 1:3, sep=""))

date1 <- date1[-c(3,4,15,34,38,40)]
df <- data.frame(lev=lev, date1=date1, y=y)
I would like to produce a new data.frame with missing days in df$date1
in each df$lev, like this:

Number of NA's in every second column
Hi R-users,
How do I calculate a number of NA's in a row of every second column in my
data frame?
As a starting point:
dfr <- data.frame(sapply(x, function(x) sample(0:x, 6, replace = TRUE)))
dfr[dfr==0] <- NA
So, I would like to count the number of NA in row one, two, three etc. of
columns X1, X3, X5 etc.
Thanks in advance

[LLVMdev] Redefining function
Hi everybody.
I've just started learning about LLVM and didn't get too far studying the
core.
I couldn't find the solution to my problem (if it has one) in the mailing
list or the source code. The problem is: how can I redefine a function
that's been called already by some other function?
Suppose I have 3 files, all compiled to bytecode through llvm-gcc (I think
