Quoting Mat <matthias.we...@fnt.de>:
Hello togehter,
i have a data.frame like this one:
No. Date last change
1 1 2012-10-04 change settings
2 1 2012-10-20 bug fix
3 1 2012-11-05 final
4 2 2013-01-15 new task
5 2 2013-01-16 Bug fix
6 2 2013-01-17 final
Calling your data frame, x and assuming the `last change` column is character,
x[x$`last change` == "final",]
will give what you want. If `last change` is a factor column (likely),
x[as.character(x$`last change`) == "final",]
If you don't have spaces in your column names, you'd avoid using the
backticks.
HTH
now i want a new data.frame, who show me only the newest entries according
to the No.
The solution look like this one:
No. Date last change
1 1 2012-11-05 final
2 2 2013-01-17 final
can anyone help me?
thanks.
Mat
