Hi All, I've been looking for a way to extract the raw numerical data from a flowset. If a flowframe in the flowset, fs, contains a column called 'FSC.H' how would I extract the actual numerical values of 'FSC.H' from the first flowframe and put them into a vector/array? I've tried fs[[1]]$FSC.H and fs[[1]]$'FSC.H' but to no effect. I've looked through the help materials and cannot find an example that does this. Any help is appreciated! Thanks, Matt

Hi Matt, To access the data in a flowFrame object you have to use the exprs() function: exprs(fs[[1]])[,1] or exprs(fs[[1]])[,"FSC.H"] This method is explained in the vignette but it is true that no example is given. We will fix that. Thanks Nolwenn M.
