Hello Mathematica People (and Sean!)


1) I'm wondering if there is any way to incorporate error bars in
LogListPlots ?  I have successfully plotted error points (one above and
below) but have run into difficulty connecting the points (forming an
"error bar") in a LogPlot.   One can see why, since lines are not
straight in LogPlots (but mine would be since they only run vertically).
 I would rather not construct the line out of series of points (due to
plotting time).  I have also considered just plotting dashed error bands
above and below the data, but would really like the standard error bars.
  I do realize that the error bars will be (and should be) funky because
of the weight of the Log Axes.


2) I am having problems with SetDirectory[] on my PowerMac.  I would
like to access another HD partition for retrieving my data.  I can't
seem to work in anything besides the "Mathematica 3.0 Files" directory.
And also have no idea how to show mathematica the way to a completely
different partition.  (much like swathing from C: to D: in the DOS
world).

Glad to be here and thanks for your help.
