[R] Help with sub-setting data.frame

[Philipp Pagel]

Your subset problem has been solved already but i'd like to add a
comment on this:

> I want all rows where TTE is equal to 0.024657534

Comparing floating point numbers for equality with '==' is problematic
so a simple df[df$TTE == 0.024657534, ] can easily fail. have a look
at help("=="), especially the note on numerical values and the exmaples.
