this is my dataset
id text
1 "red"
1 "blue"
2 "light blue"
2 "red"
2 "yellow"
3 "dark green"
this is the result I want to obtain:
id text2
1 "red, blue"
2 "light blue, red, yellow"
3 "dark green"
basically I need to put together the text from column 'text' with commas to separate the different elements
