counting characters starting point
I have three character strings represented below as seq1, seq2, and seq3. Each string has a reference character different from the other. Thus, for seq1, the reference character is U, seq2, S (3rd S from left where A is leftmost character) and for seq3 Y.
seq1 = PQRTUWXYseq2 = AQSDSSDHRSseq3 = EEZYJKFFBHO
I wish to generate a 3 by 26 matrix where 3 represent seq1, seq2, seq3 and 26 the letters of

Row median of Date class variables in a data frame
I am trying to calculate the median of each row of a
data frame where the data frame consist of
columns of class Date.
Below are my test data and best attempt at using apply.
I didn't see a solution via Google or the Baron search
site.
I'd be grateful for any suggestions or solutions.
I'm using R 2.0.0 on Mac OS X.

find date between two other dates
Hi,
I am trying to assign "Season" values to dates depending on when they occur.
For example, the following dates would be assigned the following "Season"
numbers based on the "season" intervals detailed below in the code:

Joining Dataframes
I am attempting to join several dataframes that summarize sampling effort
for different samples into one large data.frame/table.
I have looked at the merge command, but have not been clever enough to
figure out how to get it to do what I want.
A simplified example of what I am trying to do:
The dataframes I have look like this (they were generated using the table
command)

Compare date Oracle with Sys.time
I would like to import only datas of my table where DATE>today-7days.
But my datas in Oracle are 'dates' and in R are 'characters'.
now_7<-format(Sys.time()-(7*60*60*24), "%Y-%m-%d 00:00:00")
How to do?

[PATCH 0/5] btrfs: lz4/lz4hc compression
WARNING: This is not compatible with the previous lz4 patchset. If you''re using
experimental compression that isn''t in mainline kernels, be prepared to backup
and restore or decompress before upgrading, and have backups in case it eats
data (which appears not to be a problem any more, but has been during
development).
These patches add lz4 and lz4hc compression

date columns chooser
i have a data frame with 2 columns of dates.
with str(dataframe) i have ensured myself that they were indeed formatted
as dates.
one column has NA's in it.
the aim is now to make a third column that chooses date1 if it is a date,
and choose date2 if it is a NA.
i am trying
df$date3=ifelse(is.na(df$date1), df$date2, df$date1).
this leads to unexpected behaviour: the resulting column is

Videos
I am trying to get my latest installation of Centos (4.4) to see videos
when I am in www.cnn.com.
I installed mplayer using yum and that went well. But I still get the
screen from microsoft saying I need to install their plugin..
What more can I do to get these videos to work when I use either mozilla
or konqueror..
Thanks..

[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.
I put some effort into writing an introduction into

Error as.Date on Invalid Dates
Hi All,
I have an script in R which accepts user inputs for certain parameters,
particularly dates, which the user inputs as character strings.
eg:
> date1 <- "2009-01-21"
The script later parses the input via the as.Date function:
> as.Date(date1)
However, as.Date encounters an error when the string does not represent an
actual date.
eg:

patching ?merge to allow the user to keep the order of one of the two data.frame objects merged
Hello dear R-devel list members.
Following an old (2002) thread from R-help (and having myself needing to
solve the same question):
https://stat.ethz.ch/pipermail/r-help/2002-October/026249.html
I patched the {base} function "merge.data.frame" to have it work with a new
parameter called "keep_order", and I hope you might consider including this
patch (or some variation of it)

[PATCH] nv50: H.264/MPEG2 decoding support via VP2, available on NV84-NV96, NVA0
Adds H.264 and MPEG2 codec support via VP2, using firmware from the

IDCT level for MPEG2.
Known issues:
- H.264 interlaced doesn't render properly
- H.264 shows very occasional artifacts on a small fraction of videos
- MPEG2 + VDPAU shows frequent but small artifacts, which aren't there

Eliminating 'Unprintable ASCII' characters
Hi all,
I have a csv file containing words with *UNPRINTABLE ASCII* characters
(described in the following table).
Are there any viable method in eliminating these characters?
I realise that *EXTENDED ASCII* characters (i.e , ¡, ¢, £, ¤ etc) can be
removed or replaced via *"gsub"* or *"gregexpr"* functions. But am not
certain with the *UNPRINTABLE ASCII* characters.
