managing data
Dear mailing list, may some one be kind to help me solve following problem.
I am trying to write a code that will combine two tables "x" and "y". The
first columns of both tables are unique identification for the rows. The
first column of table "X" is a sub set of the first column of "Y". I need to
find the matching rows in both tables by looking on their

spliting
Dear mailing list,
I have a big data frame and each element in the matrix has two alphabets. I
want to split those alphabets into two so each element will have one
alphabet and the number of my columns will be doubled . So can some one help
with the code?
Example of what I want is to split them.

I have a file that has 90 columns and 20,000 rows and looks like

I want to write a code that will read through each row first the first looks
at the first column and then replace the three columns with 12 if it is the
same as the first column e.g. third column 11 if it is a repeat of the first
alphabet like the

Differing Variable Length Inconsistencies in Random Effects/Regression Models
Dear All,
I am quite new to R and am having a problem trying to run a linear model
with random effects/ a regression- with particular regard to my variable
lengths being different and the models refusing to compute any further.
The codes I have been using are as follows:
vc<-read.table("P:\\R\\Testvcomp10.txt",header=T)

transposing data.frames
Hello,
This must be simple...
Thanks a lot

# Imagine you have a list, e.g:
K <- list(1:10, 2:11, 9:18)
K
# Transforming to dataframe...
KK <- as.data.frame(K)
# ... one obtaines the list elements as column.
KK
# But I need the list elements as rows
# How can I achieve this? Is there a simple way to transpose
data.frames?

Transposing by a group variable
Hi R,
Can I transpose a data frame by a particular group variable?
For example:
d=data.frame(group=c(1,1,2,2,2),val=c(6,4,6,3,5))
And my output should be:
data.frame(group=c(1,2),v1=c(6,6),v2=c(4,3),v3=c(NA,5))
Many thanks,
Shubha

Maintaining repeated ID numbers when transposing with reshape
I have a dataset in "long" format that looks something like this:
ID TEST RESULT
1 A 17
1 A 12
1 B 15
1 C 12
2 B 8
2 B 9
Now what I would like to do is transpose it like so:
ID TEST A TEST B TEST C
1 17 15 12

transposing/rotating XY in a 3D array
Dear list,
We have a number of files containing similarly structured data:
file1:
A B C
1 2 3
4 5 6
file2:
A B C
7 8 9
10 11 12
... etc
My part of R receives all these data as an array: 1,2,3... 12 together
with info about dimensions (row,col,fileN) . (
Converting the data into 3D cannot simply done by:
array(x, c(2,3,2))
because breaks the structure (e.g. 1,3,5 is type mismatch)

First I would really like to thank the mailing list for help I got in the
past, as a new to R I am really needing some support on hoe to code the
following problem.
I am trying to sort some data I have in a big file. The file has 4 columns
and 19000 rows. An example of it looks like this:-

R Data Manipulation - Transposing Data by a Given Column, Like User_ID
Hello,
I'd like to transpose data to create an analysis-friendly dataframe. See
below for an example, I was unable to use t(x) and I couldn't find a
function with options like PROC TRANSPOSE in SAS.
The ideal solution handles variable quantities of SITE - but beggars can't
be choosers. :-)
Thank you in advance,

Splitting massive output into multiple text files
Dear List,
I thought it would be much easier to put a second query into a second mail.
I need to print 426*10000 blocks of variance components data, where 426 is
the number of columns of data that have 10000 permutations of variance
generated for each of them.
I have tried printing out a smaller number of permutations for a smaller
number of markers and that has worked.
However, since a

transposing data
Hi. I have repeated measures data of the form where each observation
is a trial, and trials are grouped by subject, and variables encode
whatever level of a factor was present during that trial, and the
dependent variable is response time (RT). I want to transpose the
data to a form suitable for MANOVA such that there is one observation
per subject and RT is recoded across many
