通过列上的列表子集 dataframe

Question

I have a similar dataframe, lets say df

x1    x2    x3    
Tom   Grad  35K  
Ada   Secon 21K
John  Grad  47K
Vic   PhD   52K

That I need to subset for a list of terms, as for example: listOfTerms <- c("John", "Nash", "Vic", Mary") , which should be checked against df$x1 , resulting in an output which shows me the relevant rows. I am having hard time to figure out how can it be done, could you please help me?

Answer 1

Here's an option.

library(dplyr)

mydata <- data.frame(x1 = c("Tom", "Ada", "John", "Vic"), 
                     x2 = c("Grad", "Secon", "Grad", "PhD"),
                     x3 = c("35k", "21k", "47k", "52k"))

listOfTerms <- c("John", "Nash", "Vic")

subset <- mydata %>%
  filter(x1 %in% listOfTerms)
