why is 0 not an integer?
Why when I assign 0 to an element of an integer vector does the type change
to numeric?
Here is a particularly perplexing example:
> v <- 0:10
> v
[1] 0 1 2 3 4 5 6 7 8 9 10
> class(v)
[1] "integer"
> v[1] <- 0
> class(v)
[1] "numeric" #!!

array slice notation?
Suppose I have an n-diml array A and I want to extract the first "row" -- ie
all elements A[1, ...]
Interactively if I know 'n' I can write A[1,,,,,] with (n-1) commas.
How do I do the same more generally, eg in a script?
(I can think of doing this by converting A to a vector then extracting the
approp elements then reshaping it to an array, but I wonder if there isn't a

X-window graphics -- preventing window coming to front?
When I do dev.new(), the resulting window comes to the front and grabs the
focus. Is there a way to prevent this so I can continue working in other
windows while the graphics are being produced?
Thanks

sorting question
I've asked about custom sorting before and it appears that -- in terms of a
user-defined order -- it can only be done either by defining a custom class
or using various tricks with "order"
Just wondering if anyone has a clever way to order "vintages" of the form
2002, 2003H1, 2003H2, 2004, 2005Q1, 2005Q2, etc
some have H1 or H2, some have Q1,Q2,Q3,Q4, some are just plain

regular expression submatch?
What is the simplest way to extract a matched subexpression?
Eg. in perl you can do
"hello world" =~ m/hello (.*)/
which would return 1(true) and set $1 to the matched subexpression "world".

omit empty cells in crosstab?
Perhaps this is a common question but I haven't been able to find the answer.
I have data with many factors, each taking many values. However, only
relatively few combinations appear in the data, ie have nonzero counts, in
other words the resulting table is sparse. Say we have 10 factors each with
10 levels. The result of table() would exceed the memory space (on a 32bit
machine). Is there

Preserving the type of structure
Hello,
LLVM IR flattens out the structure with one integer element to i32. Is
there any way to disable this? I want to preserve the type information of
the structure. I tried compiling the program with O0, it maintains the type
for most of the instructions but for all.
Regards,
Sangeeta

mirroring in both directions with rsync
When operating in daemon mode, will rsync check to see which file is newer and decide which direction to transfer based on that?
Example,
We have 2 terminal servers, A and B. I want users to be able to work on either server and have their home directories on both stay in sync. If a user logs into server A and changes files, the server would know to transfer the file from A to B. If they log

How to print the frequency table (produced by the command "table" to Excel
Hi,
How could we print the frequency table (produced by "table") to an Excel

Is there an easy way to do so? Thanks,

How to print the frequency table (produced by the command "table" to Excel
Hi jpm miao,
You can get CSV files that can be imported into Excel like this:
library(prettyR)
sink("excel_table1.csv")
delim.table(table(df[,c("y","z")]))
sink()
sink("excel_table2.csv")
delim.table(as.data.frame(table(df[,c("y","z")])),label="")
sink()
sink("excel_table3.csv")

searching help for partial matches
The situation is that I know there is a function and know approximately what
the name is, and want to find the exact name. Is there a way of searching
for near-matches (similar to unix apropos). For example, I know there is a
function called something like allequal (or allequals or AllEquals or...).
But ?allequal, etc, return nothing, only if I remember the name can I get
help via ?all.equal.

I am looking for other option to write the output of the print command in R
I am using sink() to write the R output to a file. This is similar to

How to wrap my (working) code in a loop or function? (loop/function newbie alert)
Dear R-helpers,
I have split a dataframe into a list with five elements, with the following
code:

I would now like to run some code (below) on each element of the list to
extract rows from the list elements; then I would like to rbind the
extracted rows into a new dataframe containing all of the extracted rows
from all of the list elements.

vectorizing a function
I'm sure I'm missing something obvious but I'm not seeing how to simply
"vectorize" a function of two or more variables.
Say I have
f <- function(x,y) if (x>0) y else -y
Now I have vectors x and y of equal length and I'd like to apply f
element-wise. I.e. conceptually
z <- f(x,y) where x, y, z are vectors of the same length
Some magic involving apply?

print comment lines on `sink'ed files?
Hi,
I am using many comment lines like this
# a comment line
in a script. Is there any way to print
comment lines when I use sink() function?
Or, are there any plans to include as
an option to sink() function in the near
future? I would not want to use cat()
function as it will look messy in the
original script file.
Thanks!

capturing the result of print in a variable?
I'd like to capture the results of a print() command so that I
can put the results in a tktext widget. I know I can redirect
the output to a file with sink. I'm looking for something like
that, but where I can redirect the output into a variable. Is
there a way to do that?
