Print the value corresponding to specific rowname from a matrix

I just have a simple R question. I have a matrix with rownames A,B,C,D

    Values

B      5
C     10

I just want to print or view the value corresponding to specific rowname. Example - The value for rowname B (which is 5)

You may simply subset by row and column name.

m["B", "Values"]
# [1] 5

Data:

m <- structure(c(4L, 5L, 10L, 21L), .Dim = c(4L, 1L), .Dimnames = list(
    c("A", "B", "C", "D"), "Values"))
