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.

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.

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?

multiple plots and looping assistance requested (revised codes)
Hi Irucka,
I tried it and was able to plot it without any errors.? Here, your code indicates you need two lines. temper[[i]][1]
?temper[[1]][1] # which is the column 1.
? Month
1???? 1
2???? 2
3???? 3
?temper[[1]][2]
#? Data1
#1?? 1.5
#2? 12.3
#3? 11.4
Suppose I use names(temper) instead of seq_along(temper)

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

"Special" LS estimation problem
Hi, I have following kind of model : Y = X1 * a1 + X2 * a2 + error
Here sampled data for Y, X1, X2 are like that :
Y <- replicate(10, matrix(rnorm(2),2), simplify = F)
X1 <- replicate(10, matrix(rnorm(4),2), simplify = F)
X2 <- replicate(10, matrix(rnorm(4),2), simplify = F)
My goal is to calculate LS estimates of vectors "a1" and "a2". Can anyone

Handle missing values
Hi everyone
I am new to R and have a question about missing values. I am trying to
do a cluster analysis of monthly temperatures and my data are 14 columns
with spatial coordinates (lat,lon) and 12 monthly values:
/lat - lon - temp1 - //temp2 - temp3 - .... - //temp12/
If I omit missing values (my missing values are 99.00) with

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.

how to use do.call("rbind", get(list(mlist)))
I have around 200 data frames I want to rbind in a vectorized way.
The object names are:
m302
m303
...
m500
So I tried:
mlist <- paste("m",302:500,sep="")
dat <- do.call("rbind", get(list(mlist)))
and I get "Error in get(x, envir, mode, inherits) : invalid first argument"
I know "rbind" is valid because
dat <- rbind(m302, m303,

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

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
