Need help on matrix calculation
Hello again,
Let say I have 1 matrix:
Mat <- matrix(1:12, 4, 3)
rownames(Mat) <- letters[1:4]
Now I want to subscript of Mat in following way:
Subscript_Vec <- c("a", "e", "b", "c")
However when I want to use this vector, I am geting following error:
Mat[Subscript_Vec, ]
Error: subscript out of bounds
Basically I want to get my final matrix in following way:
V1 V2 V3
a 1 5 9
e NA NA NA
b 2 6 10
c 3...
