Remove re-occuring text strings [closed]
I am new to R and have searched the forum for almost 2 hours now without getting it to work for me.
My problem: I have a long text string scraped from internet. As I scraped code for images were included. The are coded in a way that they start with "Embed from Getty Images" and ends with "false })});n". I would like to remove everything in between those strings. I have tried gsub() as per:
AmericanTexts3 <- gsub("Embed.*})});n", "", AmericanTexts)
But what happens then is that they remove everything between the first picture and the last picture. Do anyone know how to solve this?

You need to use a non-greedy regular expression.
Try
AmericanTexts3<-gsub("Embed.*?})});n","",AmericanTexts)
The ? matches the first occurence of the second part of the regex, so that only the part between the matches should be removed.
