Dear all
I noticed from NEWS 2.11.0,dev

Problem in Binning of a data set
Hello,
I am having problem with binning the data. I have a 50X3 matrix and I binned
the data for all the 3 columns. Using table command I got the total no. of
elements in a particular bin.
Could you please tell me how to see that what all elements are there in a
particular bin and then create a different matrix for each bin?
Thanks.

[PATCH] kexec-tools: Read always one vmcoreinfo file
vmcoreinfo file could exists under /sys/kernel (valid on baremetal only)
and/or under /sys/hypervisor (valid when Xen dom0 is running).
Read only one of them. It means that only one PT_NOTE will be
always created. Remove extra code for second PT_NOTE creation.

character count
Dear list,
I have a variable that consists of typed responses. I wish to compute
a variable equal to the number of characters in the original variable.
For example:
> x <- c("convert this to 32 because it has 32 characters", "this one has 22 characters", "12 characters")
[Some magic function here]
> x
[1] 32 22 12
Any ideas?

Problem about plot scale
There are 4 sets of array, each have 2 dimension data:x,y.
And these data comes from bkde.
I tried to plot them in one figure, but details of some lines, like
peak and where it locate, have diminished since one set of array have
fairly high y value.And another array have lots of y value near zero,
like 1e-20, 1e-10, like a long tail, while the highest y value of
these arrays is 1e-4.

Jitter in correlation matrix?
Hi,
I am just starting to use R for a graduate course, and I like how the
correlation matrix at

seems that I need to jitter the bottom panel... and I have no idea how
to do that, and I mean no idea at all. I'd appreciate any help...

Efficient nested loops
Dear R community,
I am working with huge arrays, so I spend a lot of time computing. This is
my code:
for (x in 1:dim(variable)[1]){
for (y in 1:dim(variable)[2]){
for (z in 1:dim(variable)[3]){
result <- max(variable[x,y,z,])
}
}
}
Is there a more efficient procedure to do this task?
Thanks in advance!

Na.omit on matrix, does the matrix have to have a limited size
Hello everyone, I am using the na.omit() function on a 785 x 79 matrix. When
I restrict the matrix to 10 columns for example it returns me the right
result with the na rows deleted: 756 x 10 matrix. But, if I enter the whole
matrix it returns me a 64 x 79 matrix, ununderstandable, I have no idea
why...Does anyone know what it could be? thanks

NA-values and logical operation
Dear list,
as a result of a logical operation I want to assign
a new variable to a DF with NA-values.

Help- extracting values
I have csv files imported in r each with 2 columns and many many rows. I have sorted the data in them but want to extract some values.
The first column is an ID
The second is a p-value ( now sorted in increasing order with NA's last)
I want to extract the rows with a p-value of less than 0.05)
What commands would help

plot log scale, axis original scale
I want to produce some boxplots and plot the logged values but have the
axis scale in the original, not-logged scale. It seeming like I have the
first few steps but I'm having trouble with the last. Here's what I'm
doing (which I got for the documentation for boxplot and axis). How do I
get the ticks to be labeled 2,5, and 9 of the original scale?

accessing dimension names
I have a matrix y:
> dimnames(y)
$x93
[1] "1" "2"
$x94
[1] "0" "1" "2"
.................. so on (there are other dimensions as well)
I need to access a particular dimension, but a random mechanism tells me
which dimension it would. So, sometimes I might need to access
dimnames(y)$x93, some other time it would be dimnames(y)$x94.. and so
