i'm sorry. i had an error in my previous code because i left out a
letter in the rownames.
while fixing that, i also found a solution. so i'm sorry for the
confusion.
below is my fix.
temp2 <- matrix(rnorm(10),nc=1,nrow=10)
rownames(temp2) <- c("a","b","c","d","e","f","g","h","i","j")
print(temp2)
temp2 <- as.matrix(temp2[order(temp2[,1,drop=FALSE]),])
print(temp2)
