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

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 two data sets
I would like to merge ?data1 ?that contains 100 unique ID?s with another data set ?data 2? with 150 ID?s and the age of those individuals ( the ID in data1 is a subset of the ID in data 2) I would like to merge these data1 with data2 and have the result of the merge to have the ID ordered as in data1. Can this be done in R? -- View this message in context:

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

redundant factor levels after subsetting a dataset

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: /exports

merging two data sets with no column header
I have two data sets data1 and data2 with no column names( No header). The first coluimn in both data sets represents the case ID. How can I tell R to merge the two data sets by the case ID if there is no header? Also, In data1 I have more cases and I would like the result of the merge to have all the cases in both data1 and data2. there may be some duplicate cases. I appreciate if someone can

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:

Manipulation of longitudinal data by row
I have a dataset of the form below, consisting of one unique ID per row, followed by a series of visit dates. At each visit there are values for 3 dichotomous variables. Of the 8 different possible combinations of the three variables, 4 are "abnormal" and the remaining 4 are "normal". Everyone starts out abnormal, and then either continues to be abnormal at subsequent visits,

[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)

[ 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 : [public] path = /data1, /data2, /data3 Then, under Windows, I'd like
