Hello together i have a little problem with the combine of two data.frames.
I have 2 data.frames, which look like this one:
first dataframe:
ID Name
1 Jack
2 John
3 Jill
second dataframe
ID Days Type
1 3 Training
2 1 Management
3 4 Training
At the end i want to create a data.frame like this one (the Type should be
the new column and the entry of the column should be the days):
ID Name Training Management
1 Jack 3 0
2 John 0 1
3 Jill 4 0
maybe anyone can help me, how i can do this.
Thanks a lot.
Best regards. Mat
