If you check the r-help archive for last month https://www.stat.math.ethz.ch/pipermail/r-help/2004-March/date.html at CRAN it says at the top there were 1949 messages for March. Looking at https://www.stat.math.ethz.ch/pipermail/r-help/ it shows the Gzip's size of each month's archives and from that March had 886 KB of Gzip's text from which we can estimate 1949/886 = 2.2 messages per KB. Over the last number of months there were the following number of G'zipped KB for successive months over the last 84 months: 55 19 19 18 19 17 35 27 47 55 32 50 55 41 49 50 28 53 42 81 54 99 60 84 80 76 75 78 61 83 97 141 122 96 144 173 153 226 202 131 165 183 175 168 187 240 272 262 195 236 244 285 249 326 345 392 268 455 320 418 453 468 422 447 400 323 516 478 327 450 487 535 658 573 606 659 543 655 722 677 567 519 703 886 where the last point 886KB is March 2004. Summing those number and using 2.2 messages per KB gives an estimate of about 50,000 messages over that period of time. Fitting a log linear model to those numbers gives: log(KB) = 3.2 + .043 i where i is the month number which indicates that the archive size (and hence the number of messages and possibly the user base) is growing at 4% per month! P.S. The following web page gives the number of messages per day over the last few days as a graph: http://gmane.org/info.php?group=gmane.comp.lang.r.general ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
