Dear R-helpers,
I have a dataframe like this:
ID X1 X2 X3 X4 X5 X6
49 1 1 1 0 NA NA
50 1 1 1 1 NA 1
I would like to convert a missing value (NA) that follows a 0 (zero) or
another missing value (NA) into a 0 (zero).
So, the above lines would be converted to:
ID X1 X2 X3 X4 X5 X6
49 1 1 1 0 0 0
50 1 1 1 1 NA 1
I have been struggling with this all morning, so any help you could provide
would be much appreciated.
Thank you!
Mark Na
