Similarly put the code to prepare the pptx inside a function, which e.g. takes two arguments, a dataframe (x) and a title or filename or ...
In my code below I have put your three datasets in a list and then make use of purrr::iwalk
to loop over this list to make a pptx report for each dataset. Using purrr::iwalk
the name of the dataset is passed as the second argument to the reporting function.

Normally when creating Azure resources through Bicep modules I would have 2 files. One file designated to hold the parameterized resource and another file, the main file, which will consume that module.

I've been trying my best, but not quite getting there.

QUESTION
Caused by: java.lang.IllegalStateException: Couldn't read row 0, col -1 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it.
I changed android:allowBackup="true" into "False" In android manifest.
ANSWER
Answered 2021-Aug-26 at 08:02The issue is that the getColumnIndex
method, if passed a column name that does not exist in the cursor returns -1 as per :-
Returns the zero-based index for the given column name, or -1 if the column doesn't exist. If you expect the column to exist use getColumnIndexOrThrow(java.lang.String) instead, which will make the error more clear. https://developer.android.com/reference/android/database/Cursor#getColumnIndex(java.lang.String)
As such one of the expected columns does not exist in the Cursor and as you are using SELECT * ....
then the column does not exist in the table demoTableb.
You need to make check that the table and extracted columns are compatible. That is either add the missing column to the table or remove the missing column from the columns being extracted from the cursor.
NOTE I believe that the getColumnIndex
has a bug in that it is (was) case sensitive (it certainly used to be) so the issue could be the case of the column names
If you are unsure then you may find dumping the Cursor helpful. e.g. you could use:-

QUESTION
I would like to add a variable to a data frame so that each entry of this variable is picked from an external object (i.e. not a variable of the data frame) according to entries in existing variables of the data frame.
In particular, I have a matrix param
containing parameter samples (rows) for different TOOLs (columns) and I have a data frame scenario_tab
storing variables (including seed and TOOL) for different scenarios (rows). I now want to create a new variable parameter
in that data containing the right parameter for each scenario by picking values from the matrix param
according to the seed and TOOL entry for each scenario.
Here is an example:
