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

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

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

Creating tiff with 1200 dpi
Hi all,
I am trying to create images in R suitable for journal publication. I'd
like to make an image that is 3.6" wide and 5.08" length, and 1200 dpi.
When I create a tiff file that is 800 dpi and 4x4", it works (although
doesn't look good).
But when I create a tiff that is the size and dpi I want, it doesn't
work. I get the following error:

Passing options as lists
Hi,
I apologize if this has previously been posted. I've just subscribed to the
R-help digest.
I'm writing a plotting function that uses layout() to plot several different
plots on the same device. This function uses plot(), image(), and a custom
function that uses text(). Each cell of the layout needs different par()
parameters, so what I'd like to do is pass them as lists:

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,]

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 to use the paste function to create an already used variable
Hi there,
I have the following problem
Four data frames exist:
data1
data2
data3
data4
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

[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.

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)

lattice and dates (correcting e-mail formatting glitch - sorry!!)
Hi
I'm fairly new to R and the list, so please take
what I say accordingly!
Far as I can see, strptime gives you a string in some
specified format. In order to do any kind of
numerically-based modelling with that, you need to
obtain a number to work with. One way to do this is by
getting the time with Sys.time() instead and coercing
it to a number using as.integer():
