Dears,
i need to create from a column of observations variables in a datafram like
this way:
example:
original:
ID station value
12 xy 15
12 xz 20
13 xy 16
13 xz 19
new df:
ID xy xz
12 15 20
13 16 19
i have been looking around for examples, but i could not find any how to
change my df.
I would like to make regression analysis on the values from different
production stations, so my df is very huge.
Please help on finding the package, description or anything else could help.
Thank you in advance!
Best regards
Malo
