Filtering with multiple conditions in R

Filtering with multiple conditions in R is accomplished using with filter() function in dplyr package. Let’s see how to apply filter with multiple conditions in R with an example.

Let’s first create the dataframe.

### Create Data Frame
df1 = data.frame(Name = c('George','Andrea', 'Micheal','Maggie','Ravi','Xien','Jalpa'), 
                 Grade_score=c(4,6,2,9,5,7,8),
                 Mathematics1_score=c(45,78,44,89,66,49,72),
                 Science_score=c(56,52,45,88,33,90,47))
df1

So the resultant dataframe will be

filtering with multiple conditions in R 1

 

Filtering with multiple conditions in R:

Filtering with 2 columns using or condition.

library(dplyr)
result_or <- df1 %>% filter(Mathematics1_score>45 | Science_score>45)
result_or

so the filtered dataframe is

filtering with multiple conditions in R 2

 

Filtering with multiple conditions in R:

Filtering with 2 columns using and condition.

library(dplyr)
result_and <- df1 %>% filter(Mathematics1_score>45 & Science_score>45)
result_and

so the filtered dataframe is
filtering with multiple conditions in R 3
