Subject: [R] Sort 1-column dataframe with rownames

Hi,

I have a 1-column dataframe with rownames and I want to sort it
based on the single column. The typical procedure that is recommended
in diverse posts is to use order in the index. But that "destroys" my
dataframe structure. Probabaly it is a very simple solution. Here is a
short reproducable example:

x <- c(1,3,51,2,34,44,12,33,2,8)

df <- data.frame(x)
rownames(df) <- c("A","B","C","D","E","F","G","H","I","J")

df.sort <- df[order(df[,"x"]),]
