Search column for string, if found/or not add another string to a separate column

Hi I am trying to search a very large .txt file for specific strings in one column of the file found in a separate .txt file.

Depending on whether the string is found/or not in the specified column, I would then like to add another string to a separate column.

For example:

Input file:

ID  data    name    Yes_No
1   225     name1   
2   245     name2   
3   355     name3
4   466     name4
5   230     name5

File2:

ID
1
3
5

Desired output:

ID  data    name    Yes_No
1   225     name1   1
2   245     name2   0
3   355     name3   1
4   466     name4   0
5   230     name5   1

I am hoping this will be straight forward, but I have become stuck! I would greatly appreciate some help.

Thanks

This may help:

awk 'NR==FNR{a[$1]=1;next}FNR>1{$4=0+a[$1]}7' file2 file1

If you want to get a better format, you can pipe the result to |column -t
