error in my previous message
i'm sorry. i had an error in my previous code because i left out a
letter in the rownames.
while fixing that, i also found a solution. so i'm sorry for the
confusion.
below is my fix.

sorting a matrix by the column
this is a bad question but I can't figure it out and i've tried. if i
sort the 2 column
matrix , temp1, by the first column, then things work as expected. But,
if I sort the 1 column matrix, temp2, then it gets turned coerced to a
vector. I realize that I
need to use drop=FALSE but i've put it in a few different places with no
success. Thanks.

matrix math
I am using R 2.1.1 in an windows XP environment.
I have 2 dataframes, temp1 and temp2.
Each dataframe has 20 variables (“cocolumns") and 525 observations (“rows”). All variables are numeric.
I want to create a new dataframe that also has 20 columns and 525 rows. The values in this dataframe should be the sum of the 2 other dataframe.

Aggregate Table Data into Cell Frequencies
R-help -
I have this set of aggregated tables (sample data below via dput()). And I
would like to have delayValue as the column variables with the "temp"
(temp1, temp2, temp3) values as the row variables. However I would like to
have the temp variables *aggregated into single rows* so that I have the
frequency ("Freq" | counts) of each time each "delayValue" occurs

Sweave Dynamic Graph Question
i have a time Series of IBM closing px from 1/1/2000 to today
I want to graph the time serie by dividing the graph by year and month
all the monthly graphs with the same year will go to one page. so from
1/1/2000 to 11/19/2010. i will have
11 pages, and each page will have 12 graphs (jan to dec) except for 2010.
I am able to do it in R, but when i use sweave, I can only print the last
page.

RMySQL CREATE TABLE error
Hi all-
I am stumped. The code in A. returns errors at lines 14 and 15 and fails
to load series1 and series2. However, in B., if temp1 and temp2 are
called again (which returns a "Table exists" error; see lines 14-17 in
B.) series1 and series2 load correctly. Any ideas? Also-I am open to any
suggestions to improve the code as I am a horrific programmer. Thanks

NA in eigen()
Hi,
I am using eigen to get an eigen decomposition of a square, symmetric
matrix. For some reason, I am getting a column in my eigen vectors (the
52nd column out of 601) that is a column of all NAs. I am using the option,
symmetric=T for eigen. I just discovered that I do not get this behavior
when I use the option EISPACK=T. With EISPACK=T, the 52nd eigenvector is

parse and eval character vector
Dear R-help,
I have a character vector, some elements will be numeric, some not,
and some even empty. E.g.:
temp1 <- c("abcd"," 2 ","")
I'm only interested in the numeric elements, the rest I can just throw
away. It is easy enough to loop through the vector:
temp <- try(eval(parse(text=temp1[1])), silent=TRUE); class(temp) # try-error
temp <-

Replace is leaking?
Okay, someone explain this behaviour to me:
Browse[1]> replace(rep(0, 4000), temp1[12] , temp2[12])[3925]
[1] 0.4462404
Browse[1]> temp1[12]
[1] 3926
Browse[1]> temp2[12]
[1] 0.4462404
Browse[1]> replace(rep(0, 4000), 3926 , temp2[12])[3925]
[1] 0
For some reason, R seems to shift indices along when doing this replacement.
Has anyone encountered this bug before? It seems to crop up

Lagged values problem requiring short solution time
Hello,
I am hoping someone can help tackle the problem below, for which I require a fast solution. It feels like there should be an elegant approach, but I am drawing blanks.
Take a vector 'x' with random values > 0:
x = runif(10,1,5)
Assume some reasonably small positive value 'delta':
delta = 0.75
The task is to find a solution vector 'y' of same length as

Problems with calloc function.

I have a C code in Linux, it has 7 pointers and compile e run OK, but when I
run in R happens problems with calloc function, it returns NULL.

Bugs with partial name matching during partial replacement (PR#9299)
This is a rather interesting, but I don't think it is a bug - it is
just things that "you are not supposed to do"... you are assuming
a certain evaluation order of the 4 "$" operators in
" D$ABC[D$M] = D$V[D$M] " as in:
temp1 <- D$M # 2nd and 4th
temp2 <- D$V[temp1] # 3rd
D$ABC[temp1] = temp2 # 1st

vector of permutated products
Given an x-vector with, say, 3 elements, I would like to compute the
following vector of permutated products
(1-x1)*(1-x2)*(1-x3)
(1-x1)*(1-x2)*x3
(1-x1)*x2*(1-x3)
x1*(1-x2)*(1-x3)
(1-x1)*x2*x3
x1*(1-x2)*x3
x1*x2*(1-x3)
x1*x2*x3
Now, I already have the correctly sorted matrix of permutations! So, the
input looks something like:
#input
x<-c(0.3,0.1,0.2)
Nx<-length(x)
Ncomb<-2^Nx

[LLVMdev] New backend help request.
I'm trying to figure out how to map more complex CISC instructions now. For
example on the 68000, you have things like --
add.w (a0)+,(a1)+
So that equates to:
temp1 = load a0
add 2, a0
temp2 = load a1
temp1 = add temp1, temp2
store temp1, a1
add 2, a1
How do I express that in a form for LLVM?
I see things like pre_store and post_store, but I cant find anything in the
way of documentation

Identify Objects that end with .f (and all caps)
Dear R Helpers,
I am trying to find a way to identify all the objects in my environment
that are all caps and then end with .f. I can do the all caps part pretty
easily, but I have tried a number of variations on the \ and can't get a
recognition of that operator. As a simple example
A.f<-"foo1"
AA.f<-"foo2"
aa.f<-"foo3"
A.a<-"foo4"
