Convert dataframe to table with counts where column names become row names
Can anyone explain how best to go from a dataframe to a table (or better yet
a new dataframe) of counts, where the row names in the new table (or
dataframe) are the column names of the original df.
start w/
DF1 =
Pos1 Pos2 Pos3 ....
oligo1 G C A
oligo2 U U A

plotting (a) confidence intervals (b) standard error
Hi all,
I'm building a plot of the values in tmeant (below) against positions 1 to
5, using matplot.
tmeant looks like this:

pos2 961.2841 976.3466
pos3 878.6080 1262.8523
pos4 950.8011 1129.6080
pos5 968.1080 1063.3920
I also have lower (object tl) and upper (object tu) bounds on the
confidence intervals as follows:

Avoiding for-loop for splitting vector into subvectors based on positions
...all,
I'm trying to optimize code and want to avoid for-loops as much as possible.
I'm applying a calculation on subvectors from a big one, and I get the
subvectors by using a vector of starting positions:
x <- 1:10
pos <- c(1,4,7)
n <- length(x)
I try to do something like this :
pos2 <- c(pos, n+1)
out <- c()
for(i in 1:n){
tmp <- x[pos2[i]:pos2[i+1]]
out <- c(out, length(tmp))
}
Never mind the length function, I apply a far more complicated one. It's
about the use of the indices in the for-loop. I didn't see any way of doing
that with an apply,...

Selecting the first occurrence of a value after an occurrence of a different value
Hello everyone,
I am currently working with some data where I need to select the first
occurrence of a value after the occurrence of another value.
The data has two columns, one with a time and one with occurence of certain
events.
The column of data I want to select from looks like this (and each of these
events have a corresponding time in another column).

How to change the order of columns in a data frame?
Dear all,
I have a data frame in which the columns need to be ordered. The first column X is at the right position, but the remaining columns X1-Xn should be ordered like this: X1, X2, X3 etc instead of like below.
> colnames(pos1)
[1] "X" "X1" "X10" "X11" "X12" "X13" "X14" "X15" "X16"

[PATCH v0 00/18] btfs: Subvolume Quota Groups
This is a first draft of a subvolume quota implementation. It is possible
to limit subvolumes and any group of subvolumes and also to track the amount
of space that will get freed when deleting snapshots.
The current version is functionally incomplete, with the main missing feature
being the initial scan and rescan of an existing filesystem.
