Add use of dput() to the instructions at bottom of post?
It's often difficult to figure out what a problem data set looks like when someone pastes a mess of output from R into an e-mail. The dput command, used judiciously?I would hope no one would send a 1 M data set?can make life much easier.
I wonder if it would be useful to add a hint in the instructions at the bottom of the posting page, where the list asks for self-contained reproducible

Write.table Question
Hi,
I'm trying to create an abbreviated data file from a larger version. I can
use the subset command to create a value for this data:
dat <-subset(raw.data, select=c(SNP, Pvalue))
> head (dat)
SNP Pvalue
1 rs11 0.6516
2 rs12 0.3311
3 rs13 0.5615
but when I try to write.table using:

write.csv naming file after function argument
Dear R-users,
I'm writing a program that constructs a dataset. I wish to save the dataset
to a file.
Here's a very simple example of what I'm trying to do
function(x=peter){
y <- x/2
write.csv(y, file = "...\x")
}
The problem is that I want to name the dataset as whatever the name of the
input is. In this case peter.
How do I do this?
Thank you in advance.

searching several subsequences in a single string sequence
Hi all
I am analyzing bird song element sequences. I would like to know how can I
get how many times a given subsequence is found in single string sequence.
For example:
If I have this single sequence:
ABCABAABABABCAB
I am looking for the subsequence "ABC". Want I need to get here is that the
subsequence is found twice.
Any idea how can I do this?
Thanks

R crash
Dear users,
By running the script below, R crashes systematically at the last
command, namely dev.off(), on Windows 7, but not on Windows XP.
I therefore don't provide a reproducible example and do not really
extract the relevant parts of the script because it has most likely
nothing to do with the script itself. I can do it though if you think it
might be relevant.

get and save
I have a data frame 'tmp' and a vector 'name' containing 'd2'.
I want to save 'tmp' under the name hidden in 'name', and the file must have
the same name, plus the extension '.rda'.
So I try
> tmp
x y
1 1 3
2 2 4
> name
[1] "d2"
> assign(name, tmp)
> summary(get(name))

Str info. Thanks for helping
It looks from str(SA) that Response IPS1 is a data.frame of class "anova", which probably cannot be coerced to vector.
Maybe you can use unlist() instead of as.vector()
Or something like
SA[["Response IPS1"]]["as.factor(WSD)",] ## to select the first row only, even maybe with unlist()
Without a better REPRODUCIBLE example, I cannot tell more (maybe some others

save in for loop
Dear users,
My problem concerns save() within a for loop.
Here is my code:
for (i in 1:4) {
temp <- data.frame(a=(i+1):(i+10), b=LETTERS[(i+1):(i+10)])
filename <- paste("file", i, sep="")
assign(filename, temp)
save(filename, file=paste(filename, ".rda", sep=""))
}
As you can see, save() doesn't work as I would like: (1) the object

descriptive statistics
Hi. In a data set I have a variable that takes values from 1 to 14. For each
subgroup of values of this variable, I would like to obtain some descriptive
statistics of other variables present in the data set. I've been trying with
a "for" loop but I couldn't get nothing. Could you please suggest me some
lines?

user input
Dear users,
I have looked on different sources and found different functions to
prompt the user to provide input. However, I couldn't find one that does
exactly what I'm looking for.
select.list() and menu() are nice because a graphic window appears to
prompt the user. However, the user can only choose from a predefined
list of choices. readline() and scan() are more free in the

number of items to replace is not a multiple of replacement length
Hey all,
I am writing a function in which I will have a matrix of 4 columns and a
variable amount of rows.
The first to columns will always contain be of the Character type, the third
and fourth columns
can be a variation of data types, usually characters and integers, but
sometimes lists or matrices.
At one point the code makes, for each row, a copy of that row, then it makes

Dear group,
I am trying to write functions, but as a beginner, everything is not so
obvious.
Let's say I want the results in a list of elemts like this :

Here is a function:
toto <-

{
for(i in x:y){
paste(c("tot",i),collapse="")<-(i*2)
}
}
If I type this :

I get this message error:
