Subsetting with multiple conditions in R

Subsetting with multiple conditions in R, The filter() method in the dplyr package can be used to filter with many conditions in R.

With an example, let’s look at how to apply a filter with several conditions in R.

Let’s start by making the data frame.

df<-data.frame(Code = c('A','B', 'C','D','E','F','G'),
                 Score1=c(44,46,62,69,85,77,68),
                score2=c(35,78,45,89,67,49,70),
                 score3=c(57,62,55,88,43,90,57))
df

As a result, the final data frame will be

Code score1 score2 score3
1    A     44     35     57
2    B     46     78     62
3    C     62     45     55
4    D     69     89     88
5    E     85     67     43
6    F     77     49     90
7    G     68     70     57

Subsetting with multiple conditions in R

Using the or condition to filter two columns.

Let’s load dpyr package first,

library(dplyr)
result <- df%>% filter(score>50 | score2>55)
result

as a result, the filtered data frame

   Code score1 score2 Score3
1    B     46     78     62
2    C     62     45     55
3    D     69     89     88
4    E     85     67     43
5    F     77     49     90
6    G     68     70     57

Filtering with multiple conditions in R:

Using and condition to filter two columns.

library(dplyr)
df2 <- df %>% filter(score1>45 & score2>45)
df2

so the filtered data frame is

   Code score1 score2 Score3
1    B     46     78     62
2    D     69     89     88
3    E     85     67     43
4    F     77     49     90
5    G     68     70     57
