R中的beg2char函数（qdap包）

Question

I am trying keep only that part of the string left of "keyword" . Anything on the right of "keyword" should be removed. beg2char seems like the best choice but its not doing what I thought it would do.

Please advise:

x <-"/index.php/front/yellow/searchHeading/heading/926/h_name/Architects/keyword/A//"

beg2char(x,"keyword")
# [1] "/in"

Answer 1

We could use, gsub as below:

gsub("keyword.*", "", x)
# [1] "/index.php/front/yellow/searchHeading/heading/926/h_name/Architects/"

Answer 2

If we want to keep the "keyword" in the output, then set include = TRUE :

library(qdap)

x <-"/index.php/front/yellow/searchHeading/heading/926/h_name/Architects/keyword/A//"

beg2char(x, "keyword", include = TRUE)
# [1] "/index.php/front/yellow/searchHeading/heading/926/h_name/Architects/keyword"

---

If we want to exclude "keyword" , then we would do as you did, which doesn't work, because letter "d" is part of the "keyword" . Looks like a bug to me, submitted an issue at GitHub:qdap .

But this works:

beg2char(x, "k")
# [1] "/index.php/front/yellow/searchHeading/heading/926/h_name/Architects/"
