Create a new column in R if a previous column had a particular word [duplicate]

Question

I have started learning R and the tidyverse. I want to tidy the Days column in the below table. I want to make it so that there is a new column Control which would be a logical column which would say if the sample was a control sample or a real sample. I thought about creating a column that takes the value 1 if the Days column had the word control in it and 0 if there was no "control" in it. How can I go about achieving that? Thank you all help is appreciated.

Name of the sample	Days	Compressive strength (N/mm2)
Bacillus sphaericus	7	28
Bacillus sphaericus	14	30
Bacillus sphaericus	28	37.3
Bacillus sphaericus	Control 7	22
Bacillus sphaericus	Control 14	27.65
Bacillus sphaericus	Control 28	29.3

Answer 1

After tinkering a little this seems to work.

table$Control <- ifelse(table$Days == "Control 7" | table$Days == "Control 14" | table$Days == "Control 28", table$Control <- 1, table$Control <- 0)

Though this works I don't know if this is the best way to do this, so I would still like to know how other might approach the same problem. Thank you
