Q:

Drop observation if string contains specific text with subset()

My dataframe Hosp_coord contains 173 hospitals and their locations and before mapping them I'd like to retain only those who feature the word "Trust" in their name (variable "Hosp")
HC <- read.csv("DrivetimesforR_Hosp_clean.csv",header=TRUE, stringsAsFactors=FALSE)
Hosp_coord <- data.frame(HC)
dput(Hosp_coord)
    structure(list(Hosp_code = c("RRK", "RLU", "5MX", "NO0", "NLU",

I have tried the following code but it doesn't recognize the text (it does work for numerical conditions though!).
x <- subset(Hosp_coord, Hosp=="Foundation Trust")

and x returns as " 0 obs. of 5 variables"
Thoughts?
Thanks :)

A:

We can use grep
SubHosp_coord <- Hosp_coord[grepl("TRUST", Hosp_coord$Hosp),]
nrow(SubHosp_coord)
#[1] 44
