Hi All, Thank you all very much for your previous help answering my newbie questions! I am working my way through the filter.pdf document that pertains to the flowViz package. When I copy this text from the *.pdf: xyplot(`SSC-H` ~ `FSC-H` | Visit, data = GvHD, filter = n2gate, displayFilter = TRUE, subset = Patient == "6") I see the plot indicated in the pdf. Type in this: xyplot('SSC-H' ~ 'FSC-H' | Visit, data = GvHD, filter=n2gate, displayFilter=TRUE, subset = Patient == "6") and I get a bunch of errors. The difference seems to be ' vs `. What is reason for using ` vs ' or even "? Is there a resource that I can use to look up special characters like this? I've searched through the help files/etc. and no luck so far. Thanks!
