error in my previous message

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)

this is a bad question but I can't figure it out and i've tried. if i sort
the 2 column
matrix , temp1, by the first column, then things work as expected. But,
if I sort the 1 column matrix, temp2, then it gets turned coerced to a
vector. I realize that I
need to use drop=FALSE but i've put it in a few different places with no
success. Thanks.

temp1 <- matrix(rnorm(10),nc=2,nrow=5)
rownames(temp1) <- c("a","b","c","d","e")
print(temp2)
temp1 <- temp1[order(temp1[,1]),]
print(temp1)

temp2 <- matrix(rnorm(10),nc=1,nrow=5)
rownames(temp2) <- c("a","b","c","d","e","f","g","h","i")
print(temp2)
temp2 <- temp2[order(temp2[,1]),]   # PROBLEM IS HERE
print(temp2)
