redundant factor levels after subsetting a dataset
#I have a data frame with a numeric and a character variable.
x=c(1,2,3,2,0,2,-1,-2,-4)
md=c(rep("Miller",3), rep("Richard",3),rep("Smith",3))
data1=data.frame(x,md)
#I subset this data.frame in a way such that one level of the character
variable does not appear in the new dataset.
data2=data1[x>0,]
data3=subset(data1,x>0)
#However, when I check the levels

Accessing items in a list of lists
Using R 2.6.2, say I have the following list of lists, "comb":
data1 <- list(a = 1, b = 2, c = 3)
data2 <- list(a = 4, b = 5, c = 6)
data3 <- list(a = 3, b = 6, c = 9)
comb <- list(data1 = data1, data2 = data2, data3 = data3)
So that all names for the lowest level list are common. How can I most
efficiently access all of the sublist items "a" indexed by the outer

NFSv4: Using fsid=0 but *not* exporting the root filesystem
Hi,
I would like to use the NFSv4 ability to create a "root" filesystem with
fsid=0, so that I don't have to refer to the whole path of the exported
filesystem when I mount it. However I do *not* want this root
filesystem to be mountable by any host. Is that possible and how?
E.g
Filesystem:
/exports/data1
/exports/data2
/exports/data3
/etc/exports:

I would like to create the following barplot:
I have 4 different data sets (same length + stddev for each data point)
data1

now, I'd like to plot in the following way:
data1[1],data2[1],data3[1],data4[1] with it's sd-values side-by-side at
one x-axis label (named "position 1") and each bar in different colors.

scaling axes when plotting multiple data sets
1) When adding additional data sets to a plot using "plot" followed by "lines",
is there a way to automate the scaling of the axes to allow for all data sets
to fit within the plot area?
2) I attempted to solve this by setting
xlim=c(min(c(data1,data2,data3)),max(c(data1,data2,data3)))
however, there are some NAs and Infs in these data sets, and min(data1) and
max(data1) both

Merge question
Hi:
I am a new R user. I have the following question and would appreciate your input
Data1 (data frame 1)
p1,d1,d2 (p1 is text and d1 and d2 are numeric)
xyz,10,25
Data2 (data frame 2)
p1,d1,d2
xyz,11,15
Now I want to create a new data frame that looks like so below. The fields d1 and s2 are summed by the product key.
Data3
p1,d1,d2
xyz,21 (sum of 10 from Data1 and 11 from Data2),40 (sum of 25

[ Multiple drives ]
Hello,
I have 3 hdd (120 GB, 120 GB and 80 GB) mounted on
/data1 , /data2 and /data3.
All these drives must be shared via a public access
with Samba.
For the moment, I can only share the 'data1'
directory.
[public]
path = /data1
Is there a possibility to share several disks under
the same account ?
By example :

path = /data1, /data2, /data3

problem merging two data sets ( one with a header and one without)
I have two set of data, Data1 and Data2 . Data1 has a header and Data2 does
not. I would like to merge the two data sets after removing some columns
from data2 .
I am having a problem merging so I had to write and read final data and
specify the ?header=F? so the merge can be done by?V1?. Is there a way to
avoid this step. The problem is when I do cbind the FinalData has different
column names

[PATCH] inspect: get windows drive letters for GPT disks.
This patch updates the guestfs_inspect_get_drive_mappings API call to
also return drive letters for GPT paritions. Previously this worked
only for MBR partitions. This is achieved by matching the GPT partition
GUID with the info stored in the blob from
HKLM\SYSTEM\MountedDevices\DosDevices keys. For GPT partions this blob
contains a "DMIO:ID:" prefix followed by a 16 byte binary GUID.

linear model coefficients by year and industry, fitted values, residuals, panel data
Hi R-helpers,
My real data is a panel (unbalanced and with gaps in years) of thousands of firms, by year and industry, and with financial information (variables X, Y, Z, for example), the number of firms by year and industry is not always equal, the number of years by industry is not always equal.
#reproducible example
firm1<-sort(rep(1:10,5),decreasing=F)
year1<-rep(2000:2004,10)

Increase font size in plots
Hi
I am using violin plots (type of boxplots) and I am trying to increase the font size in the plots.
It looks like that the violin plots do not work as "normal" plots as the cex parameters are ignored.
You can have a loot at the code below
require('vioplot')
data1<-rnorm(100)
data2<-rnorm(10)
data3<-rnorm(1000)
vioplot(data1,data2,data3,cex.lab=2,cex.axis=2)

couting events by subject with "black out" windows
I large datset that includes subjects(ID), Dates and events that need to be counted. Not every date includes an event, and I need to only count one event per 30days, per subject. So in essence, I need to create a 30-day "black out" period during which time an event cannot be "counted" for each subject. The reason is that a rule has been set up, whereby a subject can only be

How to use the paste function to create an already used variable
Hi there,
I have the following problem
Four data frames exist:
data1

Now I want to write a loop and temporarily store the data1, data2,
data3, data4 in a variable called data.
I tried the following...
for (i in 1:4) {
Data <- paste("data",i,sep="")

but it doesn't function. I think the problem is the definition of the

merging 3 data sets at once
Hi All,
I am looking into merging 3 data sets I know how to do that by merging data1
with data2 and then merging the result with data 3. I was wondering if it
can be done all at once so I tried,
M<-merge(data1,data2,data3, by=?ID?)
It does not work!
Any ideas?

How insert data to a column in existing csv file?
I was working with some excel files with a lot of data.
And by hand it is impossible to handle them.
So they are now converted to .csv.
With headers above the columns, like:
Data1, Data2, Data3
But now I needed to calculate the log2 value of Data1 and place the result
under Data2.
I can't find how to do that.
Does anyone else know?
I have the log2 values, but how do I get then

Match 2 vectors
Hi,
I have 2 dataframes of unequal length, and I would like to match a
factor to them so that both dataframes will have the same number of
rows.
example:
# create the 2 dataframes with unequal length
data1 <- data.frame(letters, 1:26)[-c(5,10,19:21),]
data2 <- data.frame(letters, 1:26)[-c(6,9,15:18),]
data2a <- match(data1[,1], data2[,1])
data2b <- data2[data2a,]
