how to remove values from a column based on the specific name within the group?-CodePudding

I would like to remove values (<11) in column y based on group name "genetic" within column B.

For example below:

dfa
ID     B          Y
1    genetic      10
2    life         20
3    life         10
4    genetic      10
5    life         20
6    genetic      50
7    life         25
8    life         45
9    genetic      60
10   genetic      70

output

dfa
ID     B         y
1    genetic     10
2    life        20
3    life        10 
4    genetic     10
5    life        20
6    life        25
7    life        45

Please notice that values lower than 11 were removed from dataset in the output. I would like create this conditional to deal it. Does someone could help me?

CodePudding user response：

You can use dplyr::filter() for this:

dfa %>% 
  dplyr::filter(!(Y < 11 & B == 'genetic'))
