Output of order() incorrectly ordered?
...would like to sort
based on the first column and then write the sorted data frame to a
file.
> df <- read.table("file.txt", sep="\t")
where file.txt is simply a tab-delimited file containing 4 columns of
data (first 2 numeric, second 2 character). I then do,
> df_ordered <- df[order(df$V1), ]
OR, I assume equivalently,
> df_ordered <- df[ do.call(order, df), ]
and then,
> write.table(df_ordered, file="newfile.txt", ...)
The input data file looks like this:
0.083044 375.276 680220 majority
