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

Loading .RData from Internet
Dear All,
Can you please suggest me a correct way to load the following R data frame
from the internet and save it to the hard drive?
The following is what I tried:

> read.table("http://rss.acs.unt.edu/Rdoc/library/twang/data/raceprofiling.RData")
> save(raceprofiling, file = 'raceprofiling.RData')
However, when I used dim() to check the dataset,

dataframe: string operations on columns
Dear all,
how can I perform a string operation like strsplit(x," ") on a column
of a dataframe, and put the first or the second item of the split into a
new dataframe column?
(so that on each row it is consistent)
Thanks

combining vectors into list
Hi R users
I have these two vectors:
Row <- sample(1:25, 10)
Col <- sample(1:25, 10)
Is there a way to combine them into a list, whose first component is a
vector containing the first element of Row and the first element of Col,
the second component is a vector containing the second element of Row
and the second element of Col, and so on...
Thanks you

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:

Replacing an element in a vector
Dear R helpers
I seem to have one trivial problem but can't find solution to it.
Suppose I have following input.
A = c(1, 3, 0, 5, 8) # 3rd element is 0
B = c(100, 30, 0, 25, 40) # 3rd element is 0
C = A/B
> C
[1] 0.01 0.10 NaN 0.20 0.20
Obviously, I can't divide 0/0 and hence NaN. My problem is how to replace this NaN say by 0.
So that I can

Getting the source file's name where the custom function is written
Dear R experts,
I've written some functions in a few source files (such as main.R,
control.R ...).
After loading them into R, how do I retrieve which functions are loaded
from which source file?
For example:
main.R has functions: myPrint(), myScan()
control.R has functions: setPrinter(), setData()
After loading the sources (main.R and control.R) into R, I would want to
know that

How to use conditional statement
Dear R helpers
Suppose
val1 = c(10, 20, 35, 80, 12)
val2 = c(3, 8, 11, 7)
I want to select either val1 or val2 depending on value of third quantity val3.
val3 assumes either of the values "Monthly" or "Yearly".
If val3 = "Monthly", then val = val1 and if val3 = "Yearly", then val = val2.
I tried the ifelse statement as
ifelse(val3 =

deleting the first two characters in each row of a factorized column
Hello,
I'd like to ask you something again.
I have a database and it has a column which looks like this one here:
small_factor <- factor(c("d_variable1","d_variable2","d_variable3"))
small_factor
Now the thing is that I would like to convert each element of this factorized column. Basically I want to rewrite the words in it without the first two characters:

Reducing dimension of a list object
Hi all, I generally use the Reduce() function to reduce the dimension of
list object. However in my current session I have few objects which are
actually list of list of list..(say n step). If I reduce their dimension
then I have call Reduce() function many times. Therefore my question is, is
there any 1-step way to reduce the dimension at the lowest level? Take this
example:

Remove all whitespaces
Hi
I got a string that looks something like this
1 2 3 4 5 6 7 8 9 ...
and I want it to be
123456789...
So I want to remove all spaces (or whitespaces) from my string.
Anyone know a good way of doing this?

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.
Kristian
