rbind help
Hi I have a dataset of orientation and elevation in a dataframe which I am plotting in circular. Orientation is on the range 0-360, however I need to reduce this to 0-180 as the values over 180 are not necessarily correct. I can do striae$orientation[striae$orientation>180]-180) to extract these values, but I then want to combine them back in to the original dataframe (with the elevation values). I assume rbind is the thing to use and have tried something like: test <- rbind((striae$orientation[striae$orientation>180]-180), (striae$orientation[striae$orientation<=180])) Not being a regular R user I suspect the syntax is easy when you know it!! Any help much appreciated. Best wishes mike
