Re: [R] data.frame: data-driven column selections that vary by row??

Not entirely sure I understand your problem here (your first email was a lot of reading). Would it make sense to add an extra column device_name Thus ending up with something like: Host Device Type host_Aada0ssd host_Aada1ssd host_Aada2hdd ... host_Nda3 ssd

Re: [R] reading multiple text files from web

Re: [R] summary.formula()

First you need to make the data pbc available, perhaps by: data(pbc, package=survival) Then the line: sf2-summary(... looks wrong, usually you would use the summary() function to look at the output from a function, seems to me you are missing the function here. I have no idea what this function
