Hi Matthew,
This question is a bit mysterious as we don't know what the object
"chr" is. However, have a look at this and see if it is close to what
you want to do.
# set up a little matrix of character values
tTargTFS<-matrix(paste("A",rep(1:4,each=4),"B",rep(1:4,4),sep=""),ncol=4)
# try the assignment on the first row and column
assign(tTargTFS[1,1],tTargTFS[-1,1])
# see what it looks like - okay
A1B1
# run the assignment over the matrix
for(i in 1:4) assign(tTargTFS[1,i],tTargTFS[-1,i])
# see what the variables look like
A1B1
A2B1
A3B1
A4B1
It does what I would expect.
