It would be helpful if you were to use dput to give us the sample data
since you say you have already imported it.

Selecting data frame components by name - do you know a shorter way?
Hi! I suspect there must be an easy way to access components of a data frame by name, i.e. the input should look like "name1 name2 name3 ..." and the output be a data frame of those components with the corresponding names. I ´ve been trying for hours, but only found the long way to do it (which is not feasible, since I have lots of components to select):

Reading then transposing from file
Hi,
I'm an R beginner and I'm struggling with what should be a rudimentary task.
My data is along these lines:
ID name1 name2 name3 name4
Class 0 1 0 2
Var1 A B C A
Var2 B C C A
Var3 C A B A
etc.
I'm using the following:
foo <- data.frame(t(read.table("file", header=FALSE)))
but of course now it's not using ID, Class, etc. as column names.

Oddity with names
Hi all,
I'm using R 1.5.1 on Windows 2000. The following snippet of code doesn't
seem to do anything - no error is reported, and there is no name change.
names(myFrame[,c(1:3)]) <- c("name1", "name2", "name3")
This code however works nicely:
names(myFrame)[c(1:3)] <- c("name1", "name2", "name3")

Readjusting the OUTPUT csv file
Dear R helpers
I have some variables say ABC, DEF, PQR, LMN and XYZ. I am choosing any three varaibles at random at a time for my analysis and name these files as input1.csv, input2.csv and input3.csv. So if I choose variables say ABC, DEF and PQR, I am passing the specifications of these variables to input1.csv, input2.csv and input3.csv respectively.

How to assign names in a list
Hi All
How can you associate names with a list when names have not been
assigned? For example if you have a list like this:
list2<-list(1,2,3)
list2
[[1]]
[1] 1
[[2]]
[1] 2
[[3]]
[1] 3
How do you make it look like this with names? :
f1<-1
f2<-2
f3<-3
list1<-list(name1=f1, name2=f2, name3=f3)
list1
$name1
[1] 1
$name2
[1] 2
$name3
[1] 3
Thanks for any help.

Pulling columns out of a data.frame
Hi there
Probably a very simple solution to this problem.
I have a character vector eg c("name1","name2","name3") and I want to pull
out these columns from a data.frame, converting each of these columns into
factors also.
Many thanks

Never really managed to build a for-loop with multiple running

Can anybody hint ?
