I have a matrix that looks like this:

"1", "1103", "18", "OPEN", "DEPR"), .Dim = c(7L, 4L), .Dimnames = list(
c("Sn", "SlnC", "housenum", "date", "hour", "flue", "pressurization"
), c("10019.BLO", "1002.BLO", "10020.BLO", "10021.BLO")))
How do I convert rows 1-5 to numeric? I tried mode() <- "numeric" but that doesn't change anything.
I also tried converting this to a table then converting to numeric, but I got: (list) object cannot be coerced to type 'double'
