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
"+" sign at the end of the code, pointing out incomplete command, so it is not
working:
m<-read.table("C:/backup/symmetrical.csv")
n<-subset(m, select=c("X1", "X7", "X12", X15", "X22", "X26", "X31", "X34",
"X39", "X44", "x51", "X58)
Therefore, I have no tried with row names yet.
Any suggestions? Sorry for the inconvenience. I have read some information
about this but always have the same problem with "+" and I do not have any idea
to follow.
Best,
AJ
