Remove URLs from string

Question

I have a vector of strings—myStrings—in R that look something like:

[1] download file from `http://example.com`
[2] this is the link to my website `another url`
[3] go to `another url` from more info.

where another url is a valid http url but stackoverflow will not let me insert more than one url thats why i'm writing another url instead. I want to remove all the urls from myStrings to look like:

[1] download file from
[2] this is the link to my website
[3] go to from more info.

I've tried many functions in the stringr package but nothing works.

Answer 1

 str1 <- c("download file from http://example.com", "this is the link to my website https://www.google.com/ for more info")

 gsub('http\\S+\\s*',"", str1)
 #[1] "download file from "                         
 #[2] "this is the link to my website for more info"

 library(stringr)
 str_trim(gsub('http\\S+\\s*',"", str1)) #removes trailing/leading spaces
 #[1] "download file from"                          
 #[2] "this is the link to my website for more info"

Update

In order to match ftp, I would use the same idea from @Richard Scriven's post

  str1 <- c("download file from http://example.com", "this is the link to my website https://www.google.com/ for more info",
  "this link to ftp://www.example.org/community/mail/view.php?f=db/6463 gives more info")


  gsub('(f|ht)tp\\S+\\s*',"", str1)
  #[1] "download file from "                         
  #[2] "this is the link to my website for more info"
  #[3] "this link to gives more info"
