Search list of elements for a specific pattern
Hi,
I have a list of mutations, called "mutList", of the form:
> head(mutList)
Alu
1 AluJ
2 AluJ/F(R)AM
3 AluJ/FLAM
4 AluJ/FRAM
5 AluJ/monomer
6 AluJb
It contains about 500 elements and not all of them contain the
sequence "Alu". I tried using this code:
Alu<-mutList[which(grep("Alu",mutList)==1)]
But that simply returned

Accessing a field in a data fram
raw <- read.csv(file=filename, head=TRUE,sep=",")
I've read in a csv file, and I'm looking to access a column whose name is
held in a string.
For example, I want to access raw$one or raw$two, but this will depending on
the string. Let's say that the string is decision<-"one". How would I access
raw$one?

indexing in a function doesn't work?
Hello,
I've written a small function that's supposed to save me some time, and
it's ending up killing it- the intention is to iteratively subset a dataset
fram on framevec, fit a model (either lm or nls depending on type) and
return the r2 or AIC from the model, respectively. Although as far as I can
tell in my code the plots are dependent on the fit of the model to the data
and the

De-data.fram-ize?
Dear useRs,
Is there any more elegant way to convert dataframe to a vector of all
its values than as.vector(as.matrix(x)) ? I did not have to do such
conversion yet, so I am not sure... (of course as.vector() alone does
not work).
Regards,

Extracting Numeric Columns from Data Fram
Hello,
I've got a data frame with a mix of numeric, integer and factor columns.
I'd like to pull out (or just operate only on) the numeric/integer columns.
Every thing I've found in searches is about how to subset by rows,
or how to operate assuming you have the column names. I'd like to pull
by type.
Thanks!

An index of all possible combinations of variables in a data fram e
Hello list
Does anybody know of any way to create an index of all the possible
combinations of variables (factors) in a data frame? ie for 3 factors A, B &
C we have
A
B
C
AB
AC
BC
ABC
which equates to columns 1, 2, 3, 1:2, (1,3), 2:3 and 1:3.
I realise that a function like model.matrix does this, but how to get the
seqence of the index?
Any help would be greatly appreciated.

specifying column names in a vector of characters and the use?
Hi,
What I would like to do is have a data.frame with column names and have
these column names stored as strings in another vector. Then I would like
to be able to access the data.fram columns via referencing the vector of
names. The code below shows the last few executions that failed to retrieve
the values for column named X1. Seth

how to deduplicate records, e.g. using melt() and cast()
Esteemed UseRs,
This must be embarrassingly trivial to achieve with e.g., melt() and
cast(): deduplicating records ("pw.X" in example) for a given set of
responses ("cond.Y" in example).
Hopefully the runnable example shows clearly what i have and what i'm
trying to convert it to. But i'm just not getting it, ?cast that is! So
i'd really appreciate some ones
