Subject: Split Dataframe into several
Dear R users;
Hi.
I have a problem with splitting dataframe into several.
I have a large dataframe (Length of 61000). It has 4 Columns as below:
"
Date Cases Country
1 2020-12-14 746 Country1
2 2020-12-15 324 Country1
..
6000 2020-12-13 298 Country2
.
.
"
Each country has a different number of rows and their related dates are
different. What I want to do is: Extract rows for each country and make a
new column for that case of the country.
"
Date Cases_Country1 Cases_Country2
Cases_Country3 ......
1 2020-12-14 746 25
65
2 2020-12-15 324
..
6000 2020-12-13 298 352
75
"
I used split function, but it create a list and I cannot use the data.
Please help me to fix this problem.
Sincerely
