well, these are two separate Python commands:
gp.makefeaturelayer("abc.shp", "walk")
gp.SelectLayerByAttribute('walk','NEW_SELECTION','\"hrwk05\" <> 0')
but this...
> rpygeo.geoprocessor(
> "makefeaturelayer('abc.shp','walk')",
> "SelectLayerByAttribute('walk','NEW_SELECTION','\"hrwk05\" <> 0')",
> env=myenv)
>
> File "x:\projects\rpygeo.py", line 10
> gp.makefeaturelayer('abc.shp','walk')(
> "SelectLayerByAttribute('walk','NEW_SELECTION','"hrwk05" <> 0')" )
...apparently creates a Python function call
gp.makefeaturelayer('abc.shp','walk') that is then considered to be a
function that itself is able to make sense of the argument
"SelectLayerByAttribute('walk','NEW_SELECTION','"hrwk05" <> 0')"
This is not what you want. The problem is that in
> rpygeo.geoprocessor(
> "makefeaturelayer('abc.shp','walk')",
> "SelectLayerByAttribute('walk','NEW_SELECTION','\"hrwk05\" <> 0')",
> env=myenv)
the "Select...." thing is considered to be an argument to the function
defined by the first argument of the geoprocessor (please have a look at
?rpygeo.geoprocessor - I am a bit in a hurry now because I am on a trip
to Chile and ready for a delicious dinner ;-)
So try using c( ) (after having a closer look at the rpygeo.geoprocessor
help / command syntax), or use separate rpygeo.geoprocessor calls for
the two gp. commands...
rpygeo.geoprocessor(
c("makefeaturelayer('abc.shp', 'walk')",
"SelectLayerByAttribute('walk','NEW_SELECTION','')"),
env=myenv)
I hope this helps...
