Hello List,

I have a data frame like:

	V130	V131	V132	V133	V134	V135	V136
1	0		0 		0.9		0		0.9		0		0
2	0		0		0              		0		0		0.8
3	0		0		0              0		0.9		0		0
4	0.9		0		0              0		0		0		0.9
5	0		0		                0						
6	0		0		0		0.9		0		0		0.9
7	0		0 		0.8		0              0		0		0
8	0.9		0		                0		0.9		0.8		0
9	0		0		0		0.9		0.9		0		0
10	0		0		0		0		0		0		0.9

I would like to fill the empty cells with a 0... how to address those empty cells?

thanks for your help!

best,
Simone
