Hi Nathan,
I know the field calculator and used it quite extensively. The functions
are powerful but it can be quite cumbersome to use (I hope the future
saved expressions can help for this, having to copy and paste from an
external text editor is a pain). I would like to be able to:
* sort according to several columns
* auto-increment a field just by dragging the mouse like in a spreadsheet
* for a numeric field, see quickly the basic statistics of the selected
features (average, sum, maybe also min and max). Currently, I would have
to go to Vector->Analysis->Basic statistics and select the field. I
prefer to copy and paste the selected features to either LibreOffice or
Excel and select the column I want to see the sum, but I don't know what
to say each to people when I show them how to use QGIS (we work on
networks so we are often interested in the length of lines in a selected
area for example).
* select several cells and copy/paste them
* hide columns temporarily
* having formulas that stay as formulas and are updated when the source
data is updated, be it other fields, geometry, etc. ( I think I saw
something about this but I do not know the current status)
Anyway, just a few ideas I had in mind, probably more would come later.
I wanted to implement the basic statistics of selection myself, but am I
not sure of where to put this, there is no status bar.

Leyan,
What kind of stuff were you after? QGIS does have a field calculator
which can do expressions for calculations.

Subject: Re: [Qgis-user] Editing Data in Attribute Table/How Do I
Install MultiEdit
Hi Ben,
If you work with shapefile, you can open the dbf file with LibreOffice
and do more advanced editing here. Be careful not to delete or reorder
lines. I agree it would be very nice to see these features included in
the attributes editing.

Hi All,
A couple of questions re editing data in the attribute table:
1) Is it possible to add/change attribute data to multiple selected items in
one single operation (I'm presently selecting the items, opening the attribute
table, ticking show selected only, and then manually pasting the relevant data
into the row for each item)? Surely there is a more intelligent way to do this?
2) Is there a "find and replace" tool that can be used to change matching data
to a new value when editing data in the attribute table?
3) The MultiEdit plugin (http://plugins.qgis.org/plugins/MultiEdit/) sounds
like it may be helpful when editing data in the attribute table but I haven't
been able to install it (it doesn't appear in the list of plugins in the plugin
installer). How do I install this plugin?
Thanks for your help,
Ben
