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. cu Philipp -- Dr. Philipp Pagel Lehrstuhl für Genomorientierte Bioinformatik Technische Universität München Wissenschaftszentrum Weihenstephan 85350 Freising, Germany http://webclu.bio.wzw.tum.de/~pagel/ ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
