Tena koe Jessie Lots of ways of doing this. Perhaps the easiest, if your data is formatted as you suggest, is to use substring; e.g., substring(yourData$Sample, 1, 4) should give you the sites.
Otherwise, you might need to investigate regular expressions. HTH .....

I've read through tutorials and am still stuck. I have a column in my data called "Sample". The samples are listed as four sites (SFHS, SFLS, NFLS, NFHS) with tree numbers (01 through 23) and replicates per tree (A and B). So, a typical sample name would look like: SFLS01A or SFHS05B. I need to split this column into three columns (site, tree, and rep), but I can't figure this out. Does someone have advice / suggestions? Thanks so much!
