Duplicate rows when I combine two data.frames with merge!
...-rep(5,200)
age<-c(age3,age4,age5) #combines ages into one vector
unique<-1:1000 #gives each fish a unique id
pop<-data.frame(unique,length,age)
pop<-pop[sample(1:1000,size=1000,replace=FALSE),] #randomized the order of
pop
c.one<-pop[sample(1:1000,size=100,replace=TRUE),]
a.one.qtr<-c.one[sample(1:100,size=25,replace=TRUE),]
merge<-merge(c.one,a.one.qtr,by="unique",all=TRUE)
What I would ultimately like to have is one row for all 100 in the sample
and three columns (unique, length, age). And then some way to identify the
25 individual selected rows.
Thank...

question about time series objects
Hi All,
I have a very simple question about a time series object: how to access
values for a particular year and quarter (say)?
Suppose, following
http://www.stat.pitt.edu/stoffer/tsa2/R_time_series_quick_fix.htm
I have read in data as a time series; here is how it looks.
* Qtr1 Qtr2 Qtr3 Qtr4
1960 0.71 0.63 0.85 0.44
1961 0.61 0.69 0.92 0.55
. . . . .
. . . . .
1979 14.04 12.96 14.85 9.99
1980 16.20 14.67 16.02 11.61*
How do I access the value for 1961 quarter 3 (say)?

x axis dates
The following data spans out to 2012 and when graphing out the data - R
defaults dates on x axis only shows the years eg 2005 2007 2009
My question is how can I get the graph to show more dates on the axis - eg
every qtr or 6 months or every month etc
PRODUCT,DATE,AMOUNT_1,AMOUNT_2
A,3/1/2005,126647400,121942966.2
A,4/1/2005,121942966.2,122244045
A,5/1/2005,122244045,117227480.04
A,6/1/2005,117227480.04,117913720.32
A,7/1/2005,117913720.32,116767296.

(Newbie) Functions on vectors
Folks,
I want to make the following function more efficient, by vectorizing it:

of unequal length!");

Time series questions
...t problem I have is that 4th quarter 2010 is missing--not even NA,
there is no record for Year=2010 and Quarter =4, so instead of 260 rows, I
only have 259. To solve this, I created a temporary DF with "Year" and
"Quarter" that was complete
Yr.temp = rep(1947:2011, rep(4,65))
Qtr.temp = rep(1:4, 65)
Temp.df = data.frame(cbind(Yr.temp,Qtr.temp))
and merged the two, so now I have the NA's.
so, my DF is gdpdata with the above four columns, 260 rows.
My first question: what is the difference between
gdp.ts <- ts(gdpdata$GDP, start=1947, end=2011, fr=4)
and
gdp2.ts <...

Help with date specification
Hi everyone,I have a data daily data (x) for 10 years starting from
04-01-1995 to 03-31-2005.
I was able to get the yearly sum for the ten years using
aggregate(x, years, sum).
But this gave me the yearly sum for 1995 (Apr- Dec); 1996 (Jan-Dec)
---------2005 (Jan-Mar).
But I want to get the aggregates for Apr-1995 to Mar 1996, Apr 1996- mar
1997 and so on.
your help will be higly appreciated.

aggregate.ts help
Hi,
I have a ts object with a frequency of 4, i.e., quarterly data, and I would
like to calculate the mean for each quarter. So for example:
> ts.data=ts(1:20,start=c(1984,2),frequency=4)
> ts.data
Qtr1 Qtr2 Qtr3 Qtr4
1984 1 2 3
1985 4 5 6 7
1986 8 9 10 11
1987 12 13 14 15
1988 16 17 18 19
1989 20
If I do this manually, the mean for the 1st quarter would be
mean(c(4,8,12,16,20)), which is 12. But I am wondering if there is a R
function that c...

[PATCH 0/6] p2v: make it more independent (part #2)
As preliminary steps in splitting virt-p2v to an own repository,
continue making p2v more independent within libguestfs. This is
accomplished by the following changes:
- have only the authors in the about dialog, and read them from a local
AUTHORS file
- few more cleanups
This is still not complete, although I believe most of the work needed
is done, and it still makes p2v usable within

[PATCH] libvirt: disallow non-local connections (RHBZ#1347830)
If the connection is not local, paths of disks will refer to the remote
host, which were mistakenly handled as local paths (in the best case
failing to open a non-existing disk, and in the worst case opening a
different disk!).
In case the disks are remote resources like ssh or ceph, nothing
guarantees that the hostname can be reached from the local machine, or
even that it is actually the same on
