I just have started using R. I am working with abundance data (57 parasite species found in cod) and I would like to know if there is possible to transform all the data matrix. I read that in LDA it is possible to do it with log transformation but I need log (x+1) transformation because I have many "0". It is important for me because I am testing random Forest and LDA and I did 160 random files (training and testing files).
Thank you very much All the best -- View this message in context: http://www.nabble.com/How-transform-log%28x%2B1%29-all-data-matrix--tf4587543.html#a13094677 Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
