Sorry for not answering earlier. You mention some open issues. Let me ask some more questions to clarify these.

Mainly three issues remained uncovered: a.) converting input > data/vectors to factors (is useful sometimes), It you transfer a variable to R and then just apply the function factor in R, it is converted to a factor. Do you need more functionality? b.) importing data as > matrices (for contingency tables, e.g. for a Fisher exact test) and I assume by importing you mean import into the spreadsheet. The basic unit for data transfer in our framework is an array of a single underlying scalar type. (character, (real) number, complex number, time&date). So transferring a matrix in either direction is there. There is, however, one major concern. Spreadsheet programs don't care too much about missing values. I have not looked into the details of this in Calc, but I think that it is important to be careful about this problem in the interface. c.) > converting a data range to multiple vectors vs independently selecting > the data ranges for the multiple vectors. When a range is transferred as a dataframe, in R you can immediately access the columns as vectors. What kind of additional functionality do you think is needed? -- Erich Neuwirth, University of Vienna Faculty of Computer Science Computer Supported Didactics Working Group Visit our SunSITE at http://sunsite.univie.ac.at Phone: +43-1-4277-39464 Fax: +43-1-4277-39459 --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
