memory problem for R
Hi,
I try to use lm to fit a linear model with 600k rows and 70 attributes.
But I can't even load the data into the R environment.
The error message says the vector memory is used up.
Is there anyone having experience with large datasets in R? (I bet)
Please advise.
thanks,
Yun-Fang

error bars around a point
All
Is there an R command to produce error bars around
a plotted point. Crawley's book uses the command
error.bar() but my version of R rejects it. Must be an
S+ command(?).
Thanks

ANOVA procedure on the sufficient statistics
Hi,
I have a two-way anova with unequal cell numbers that I want to analyze.
The problem is I don't have individual observations of the data.
I only have the sufficient statistics (mean, variance, # of observations) for each cell.
Is there any existing function in S-plus that would allow me to do aov() with the sufficient statistics?
The table is like
G1 G2 G3 G5 G6

group calculations with other columns for the ride
Hello,
I can get the median for each factor, but I'd like another column to go
with each factor. The nm column is a long name for the lvls column. So
unique work except for the order can get messed up.
Example:

matrix manipulations
Hi,
I am having some difficulties with matrix operations. It is a little hard to explain it so please bear with me. I have a very large data set, large enough that it needs to be split in parts in order to deal with. I can work things on these "parts" but the problem lies in adding together these parts for the final answer.
So that been said, let's say that i split the data in 2

how to combine data of several csv-files
Hello,
I'm looking for a solution for the following problem:
1) I have a folder with several csv files; each contains a set of
measurement values
2) The measurements of each file belong to a position in a two
dimensional matrix (lets say "B02.csv" belongs to position 2,2
3) The size of the matrix is fix
4) I cannot assure to have a csv file for each position
5) Each position

Lattice: multiple data sets on same plot
Hi,
I have two data sets; one is a population and the other a sample of
that population. I am trying to plot both on the same trellis display.
# Example data set with two numerical attributes and two categorical
pop <- data.frame(var1=rnorm(2000, 2000, 500), var2=rnorm(2000, 2000, 500))

median of binned values
Dear list,
I have a vector (array, table row, whatever is best) of frequency values
for categories (or bins), and I need to find the median category.
Trivial to do by hand, but I was wondering if there is a means to do it
in R in an elegant way.
The obvious medioan(vector) returns the median frequency for the binns,
and that is not what I want. i.e,:

lapply( *, names) -- bug ?!
This came on S-news
The more direct test being
sapply(c(a=1,b=2), names)
Problem:
R ("all" versions)
behaves the same as S+5.1, which is wrong IMO.
{since some might disagree, I didn't yet post to R-bugs ..}

Using a 'for' loop : there should be a better way in R
I need to apply a yearly inflation factor to some
wages and supply some simple sums by work category. I
have gone at it with a brute force "for" loop approach
which seems okay as it is a small dataset. It looks
a bit inelegant and given all the warnings in the
Intro to R, etc, about using loops I wondered if
anyone could suggest something a bit simpler or more
efficent?

Interpreting factor*numeric interaction coefficients
Dear all,
I am a relative novice with R, so please forgive any terrible errors...
I am working with a GLM that describes a response variable as a function of
a categorical variable with three levels and a continuous variable. These
two predictor variables are believed to interact.
An example of such a model follows at the bottom of this message, but here
is a section of its summary table:

[LLVMdev] powerpc-darwin8 build/test status page
Hi,
For anyone who might be interested, I've thrown together a little
page to track my builds of llvm and clang, both release 3.0 and
svn-trunk, on powerpc-darwin8.
http://www.csl.cornell.edu/~fang/sw/llvm/
I'll update the list of logs each time I svn-update and build. It's
nowhere as nice as a real buildbot page, but it's better than nothing.
3.0 still has over 20 test

cbind with vectors of different lengths?
Hello R help
I have a dataframe, with 71 samples (rows) and 30 variables. I got linear models for some of the variables,? and I want to join fitted and residuals of these models to the data frame. Sometimes, these vectors have the same length of the dependant variable, but in a few cases, NA values can be found on my data, and therefore, both fitted and residuals have a few rows less than the
