However, when I use the same code introducing the total number of columns
(around 2000) it's not working.
I have checked all labels several times in order not to commit mistakes. For
this reason I have copied and pasted all labels from a database to a
spreadsheet where I
12 X22 X31
X1 1 3 5 7
X12 3 7 5 2
X22 6 7 4 9
X31 1 1 1 1

Sorry so much
data.frame to matrix
dat2<-as.matrix(dat1[(select=c("X1","X12","X22","X31")),(select=c("X1","X12","X22","X31"))])
is.matrix(dat2)

You're missing a )
You close c() but not subset().
That's the most common cause of incomplete commands: it often works to
just keep typing ) until you get the regular prompt.

For a start, you are missing a quote and a parenthese on the
statement; probably should be: (another quote was also missing)
n<-subset(m, select=c("X1", "X7", "X12","X15", "X22", "X26", "X31",
"X34", "X39", "X44", "X51", "X58"))
Not sure what you want with the rownames; an example would help and
Hi there and thanks in advance.
I have a large symmetrical matrix stored in a text file. After load in R I
would like to extract the same number of columns and rows (symmetrical
submatrix) using their labels.
I have tried this code in order to extract columns, but R console gives me the
