How to select individual cell instead of entire rows?
In table below, I need to select the two -99 cells under Value1 and Value2 column, and delete them. Can someone help? When I used select where, the entire row is selected.
test1 | Value1 | test2 | Value2 |
2 | 5 | 3 | 1 |
3 | 5 | 4 | -99 |
4 | -99 | 5 | 443 |
-88 | 7 | 6 | 234 |
77 | 9 | -76 | 3 |
5 | 0 | 65 | 45 |
Thanks
Just in case you were looking for a non-scripting approach, you could use search and replace (Ctrl+F), or you could use Column Properties and set -99 as a missing value code. If you use the search option, be sure to leave the Replace With box empty (i.e no space).
Selecting a single cell, in the context of "Select Where" isn't really available. But addressing a single cell can be done and then the cell value can be changed, or the cell color can be changed. Here is an example of how to do this:
Names Default to Here(1);
dt=current data table();
dt:Value 2 << color cells("Red", dt<<get rows where(dt:Value 2 == -99));
davyvy,
One approach is to simply clear the value of the cell and replace it with missing value (essentially same as delete). So..
:Value1 << Set Each Value( If( Value1[ ] == -99, ., Value1[ ] ) );
:Value2 << Set Each Value( If( Value2[ ] == -99, ., Value2[ ] ) );
I've found that Set Each Value is quite fast. I ran a test on a 5 column, 6.6M row table and each of the operations above completed in ~2s.

alternatively, you can use the recode option to change the -99 to missing values or whatever value you want. just right click the column from the column list on the left and select recode. the rest is self explanatory.
