Warning message: numerical expression has 1000 elements: only the first used
Hi,
Your mistake seems to be in
sum(v[1:x])
You create "x" as a vector but your treat it as a single number.
v[1:x] expects "x" to be a single number and only considers its first
element which is 1.
If I understand your query correctly, the following might handle your
problem:
sum.vec <-NULL
for (x in 1:1000){
t <- rbinom(1000, 1, 0.5)
v <- replace(t,t==0,-1)

submission of some functions to base package
Dear all,
Actually I could not decide who to contact, then decided to post here. If
not appropriate sorry for that.
I have written some functions in R which might be supposed to available in
the base package but not available. I am wondering that how can I submit
those functions to that package?

Customized R Regression Output?
Hello R-Experts,
I am facing the problem that I have to estimate several parameters for a lot
of different dependent variables.
One single regression looks something like this:
y = beta0 + beta1 * x1 + beta2 * x2 + beta3 * x1 * x2 + beta4 * x4 + beta5 *
lag(x4,-1)
where y is the dependent variable and xi are the independent ones. Important
to me are the different estimates of betai and their

How to measure level of similarity of two data frames
Hi group,
I've been thinking of calculating euclidean distance between each column of
a data frames that each consists of standardized numerical columns.
However, I don't know if there's a way of summarizing the overall distance
by some kind of metrics. If anyone know a proper way of doing so and/or a
package I would greatly appreciate your suggestions. Thanks very much!

Dear all,
I want to concatenate the elements of two vectors such as

two questions about character manipulation
Dear all,
I want to manipulate a character string such as
ex<-"cbind(data$response1,data$response2)"
in R in two ways:
1) extracting the "response1" portion of ex
2) replacing "$" with "."
I am wondering that is it possible efficiently doing these in R?

remove descriptions from output
Dear R users,
I'd like to remove some descriptions when I use "filter".
> filter(1:10, rep(1, 3))
Time Series:
Start = 1
End = 10
Frequency = 1
[1] NA 6 9 12 15 18 21 24 27 NA
That is, I want only this
[1] NA 6 9 12 15 18 21 24 27 NA
Thank you in advance.

Error: could not find function
Hi
Do I have to load/download the whole package over and over again everytime
when I use the R-Project?
It often prompt me the error message "could not find function"- but I'm
rather sure I have used the function before so I'm not entirely sure it
couldn't find it again when I shut down the computer or so.
Is it to do with directory or clashing with other software?

encrypting existing partitions/disks
Hello,
Has anyone wrote a how-to or a guick guide on how
to encrypt an existing partition/disk using gbde?
I've tried to search in the net but i cudn't find
any. Is it possible to just move the existing data
on my disk, cleanup the disk and encrypt using gbde,
attach to the system, then move back the data to the now
encrypted disk.
Thanks,

Correlations by group
I'm aware that S N Krishna asked the same
question. However, I have failed to implement the
posted solution for running rank order
correlations on multiple subsets of data using the by() function.
