flac-1.1.1 completely broken on linux/ppc and on macosx if built with the standard toolchain (not xcode)
Sadly the latest optimization broke completely everything.
The asm code isn't gas compliant. the libFLAC linker script has a typo,
disabling the asm optimization and/or altivec won't let a correct build
anyway.
Instant fixes for the asm stuff:
sed -i -e"s:;:\#:" on the lpc_asm.s
to load address instead of addis+ori you could use
lis and la and PLEASE use the @l(register)

creating vectors from data-frames
I am having a problem with creating a vector from a rows or columns, I
searched around and found as.vector(x), but it does not seem to do what it
says it does
I have included an example below, of doing what would seem to be the method
required to create a vector, but instead it creates a one row data frame.
What is required to actually create a vector.
Many thanks

var-covar matrices comparison:
Hi,
Using package gclus in R, I have created some graphs that show the
trends within subgroups of data and correlations among 9 variables (v1-v9).
Being interested for more details on these data I have produced also the
var-covar matrices.
Question: From a pair of two subsets of data (with 9 variables each, I
have two var-covar matrices for each subgroup, that differ for a
treatment on one

Select single column, preserve name?
Hi, list-
?? I've got a large list of multi-column data and I'd like to filter
it according to a threshold, such as, "show me the values that are
above 0.4 for each line."
For instance, if the line of data were:
> line
v1 v2 v3 v4 v5 v6 v7 v8 v9
1 -0.32 0.66 -0.35 -0.82 0.38 0.66 -0.02 -0.11 -0.64
I can do this

to remove columns and rows
Dear,
I am using R I'm trying to identify and remove columns and rows in a data
frame that are has elements equals. For example in dataframe below. The
columns 1, 2,3,4,5 ,6 and 10 (file1) has elements equal then should be
removed. How can I ask R to remove those columns with same elements in new
dataframe (file2) to result a matrix as follows:
file1
1 0 2 2 1 1 5 1 1 1

how to calculate average of each column
Hey All,
I have a large dataset and I want to calculate the average of each column
then return a new dataset.
Here is my question: I dont know if there is a function that can allow me
to calculate the average every 60 records of data in the whole dataset, and
return a new data frame. Not sure if I have to divide the dataset first for
every 60, then do the mean or can i directly do that.
thanks

How to select a whole column? Thanks!
Dear all,
I hope to remove a whole column from a data frame or matrix (> 2000
columns). All value in the column are same. The first thing is to
select those columns.
For instance, I hope to remove the V3~6 column, for all the value in
those colume is zero.

code for "permutative" operation
Hello, I need some form of a "permutative" operation on a numeric
vector x
x = (v1, v2, v3, ..., vN)
that produces
x.r = (v1, v1+2, v1+v2+v3, ... v1+v2+...+vN)
If the operation is sum() I can run
x <- 5:8
m <- matrix(rep(x, length(x)), ncol=length(x))
(x.r <- rowsum(m * upper.tri(m, diag=TRUE), rep(1, length(x))))
But there's two things I don't know and kindly

Help on efficiency/vectorization
Dear R users,
I am trying to extract the rownames of a data set for which each columns
meet a certain criteria. (condition - elements of each column to be equal
1)
I have the correct result, however I am seeking for more efficient (desire
vectorization) way in implementing such problem as it can get quite messy if
there are hundreds of columns.
