R help - Sep 2007 - vector name

I have got a list named "filtered", I would like to construct alist
named
"fdata" as following:

fdata <- cbind(matrix(unlist(filtered),ncol=28), myregime)		

If I try names(filtered), it gives all the correct name for each vector, but
if I try names(fdata), it appears "filtered[[1]]" 
"filtered[[2]]" ...,

How can I keep the name in "fdata"? Could anyone give me some advice?

Hi,

Either of the following should work (I assume there are 28 elements in your
list):

fdata <- cbind(as.matrix(as.data.frame(filtered)), myregime)

fdata <- cbind("colnames<-"(matrix(unlist(filtered),ncol=28),
         names(filtered)), myregime)

You don't tell us quite enough about your data, but:

This would appear to giva a matrix, not a list? Did you perchance intend

do.call("cbind", c(filtered, list(myregime))

or maybe just

data.frame(filtered, myregime)

or

as.matrix(data.frame(filtered, myregime))
