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

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.

Problems with calloc function.
Hi all,
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.

how to convert string to object?
temp = "~aparch("
temp1 = paste(temp,1, sep = "")
temp2 = paste(temp1,1, sep = ",")
temp3 = paste(temp2, ")",sep = "")
temp 3 is a character but I want to convert to formula object. How do I do
this?

Loading in Large Dataset + variables via loop
Hello, I'm new to R with a (probably elementary) question.
Suppose I have a dataset called /A/ with /n/ locations, and each location
contains within it 3 time series of different variables (all of 100 years
length); each time series is of a weather variable (for each location there
is a temperature, precipitation, and pressure). For instance, location 1
has a temperature1 time series, a

Handle missing values

I am new to R and have a question about missing values. I am trying to

while fixing that, i also found a solution. so i'm sorry for the

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.

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

I tried it and was able to plot it without any errors.? Here, your code indicates you need two lines. temper[[i]][1]

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

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

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

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:

Nx<-length(x)
