R中的grepl函数

Question

I have a data set and I want to find the rows which include a specific word "result". I used the following function but it seems it doesn't work correctly. Any suggestion?

data$new<-data.frame(grepl("result",col1)) 


data:
col1                            col2
ABC result VDCbvdc home          22
fgc school                       34
university result home exam      45
exam math stat                   65

Answer 1

try data$new <- grepl("result",data$col1)

data$new should be assigned to a vector, but you're trying to feed it a data frame. also, col1 only exists inside data , so you'll need data$col1 .
