Hi All,
I have the data shown below... I'd like to find the first non-zero value in a row (highlighted yellow, in this case always a '1') and replace this value with a zero.
Suggestions appreciated!
Thanks in advance
Matt
PS This is seabird ringing/banding data. The first value is the year of ringing as a chick, abd this study is focussed on sightings of adults. The original data is not easily accessible)
