filter a dataframe from specific variable value superior to in r

To filter a dataframe in R based on a specific variable value being greater than a certain threshold, you can use the filter function from the dplyr package.

Assuming your dataframe is called df and the variable you want to filter on is called my_var, you can do the following:

main.r
library(dplyr)

filtered_df <- df %>% filter(my_var > threshold_value)
71 chars
4 lines

In this example, you would replace threshold_value with the actual threshold value you want to filter on. The %>% operator is used to pipe the dataframe into the filter function. The resulting filtered_df dataframe will only contain rows where my_var is greater than threshold_value.

Alternatively, you can also use the base R function subset to achieve the same result:

main.r
filtered_df <- subset(df, my_var > threshold_value)
52 chars
2 lines

In this example, you would replace threshold_value with the actual threshold value you want to filter on. The resulting filtered_df dataframe will only contain rows where my_var is greater than threshold_value.
