questions about axis
Dear helper.
I am a beginer.
I have difficulties to handle axis. I want to draw axis label such that axis has range of [-0.4,0.4] with intervel 0.2 for x and y axis.
Some part of range do not have data points. Thus, plot does not show whole range. How can I enforce plot to depict the whole range regardless of existence of data points ?
Another problem is that when I depict axis labels, some

Summing values by weekday and weekend - based on daily dates
Hi, all
Here I created a data frame like
mydates<- seq(as.Date("2010-05-29"), length = 43, by = "day")
myvalues<-runif(43,0,1)
myframe<-data.frame(dates=mydates, day=weekdays(dates), value=myvalues)
dates day value
1 2010-05-29 Saturday 0.14576143
2 2010-05-30 Sunday 0.37669604
3 2010-05-31 Monday 0.74813943

counting weekday in a month in R
Hi,
I am trying to count weekday of the month using R. For example, 1/4/2001
is the 4th weekday of Jan, and 1/5/2001 is the 5th weekday of the month, and
1/8/2001 is the 6th weekday of the month, etc. I get as far as extracting
the weekdays from a sequence of dates (see below). But I have not yet
figured out a fast way of counting without using a For Loop. Does anyone
know how to do such counting

New package ISOweek: Week of the year and weekday according to ISO 8601
ISOweek is a small package which contains functions to substitute the %V and
%u formats which are not implemented on Windows.
In addition, the package offers functions to convert from standard calender
format yyyy-mm-dd to ISO 8601 week format yyyy-Www-d and vice versa.

Problems with weekday extraction from zoo objects
Hi Folks!
I'm struggling with dates - but enough about my personal life.....
I have two daily time series files. In one (x) the date format is Y/m/d
and the other (y) is d/m/y. I used read.zoo on both and they read into
R with no problem.
Then I use: weekdays(as.Date(x$DATE)) and get what I expect - all the
days of the week in my data set.
When I use:

Rsync, CP and Cron job workaround?
Hi,
I have a Linux based NAS, which unfortunately appears to be a bit
underpowered, heres why I say that:
5 PC's backup to the NAS on a weekly full with hourly incrementals 7 days a
week between 7am and 6pm (2 week retention policy). There is no problem with
that.
Where there is a problem is getting that data off the NAS to the USB
attached storage for off site (2 disks swapped weekly). The

Confidence intervel for regression line
Hi all,
For the simple linear regression, I want to find the input "x" value so
that the
lower confidnece limit is a specific number, say 0.2.
In other words, I want to find the value of x so that the lower
confidence bound crosses the horizontal line 0.2.
Is there a simple way (an R function) that can do this?
Thanks.

R 1.7.1 beta is out
I've wrapped up the first beta release of 1.7.1. It is available on
http://cran.us.r-project.org/src/base/
Things are set up so that a new version should be generated every
morning at 7am local time (Wisconsin), until the day of the final
release. (And consequentially, although it will propagate to the rest
of CRAN, it will most likely be out of date by then, so do get it from

rsync takes long pauses in xfer ?
Hey folks,
I did some googling on this but did not come up with much. I'm using
rsnapshot which uses rsync, and I notice some pretty long pauses in
the xfers as you can see on this graph from "munin". THe machine in
question right at the moment is doing nothing but rsyncing (
rsnapshoting ) some 12T of NAS storage to local disk, so there is
nothing else going on at all.

LDAP logonHours problem
Hi!
I have a problem according to the logonHours setting in my Samba Domain.
Users are in LDAP, and everyone has a logonHours attribute, which could be:
- login is possible at any time
- login is only possible between 7AM and 12PM(mindnight), 7h-24h in 24
hours format, I'm going to use 24h format here in this post.
Samba manual states than logonHours is a 168 bit mask, starting with
