Hi Tony,
The dimnames parameter is only in the matrix() function, not in the
as.matrix() function.
#So you can do:
A <- matrix(rbind(Fert,M), nrow = nrow(rbind(Fert,M)))
A
#This for example will allow you to name your row and colums.
B <- matrix(rbind(Fert,M), nrow = nrow(rbind(Fert,M)), dimnames =
list(c("r1" , "r2", "r3"), c("c1", "c2", "c3")))
B
