Greetings - I have a question regarding a relatively simple data transformation, and wondering if it can be automated in R (or any other platform). For large input datasets with numeric density and size, is there a function that can reformat the data into a single vector for statistical analyses?
For instance, for the two column dataset: numeric density size 5 5 4 8 3 9 4 10 How could the following output vector be automated: size 5 5 5 5 5 8 8 8 8 9 9 9 10 10 10 10 Last, what if there was a third column for 'location', and the desired output would be a single vector for each location? I appreciate any assistance. It seems like a straightforward process, but I can't find any example code in the reference books I have.
