I have some html I am trying to manipulate eg:

imgsrc=\"Myimage1.file/img2222.jpg"

I want to gsub this so that I get

<img src="Myimage1.file/img2222.jpg"

I have tried

gsub("imgsrc=\\","<img src=",mydf$V1,fixed=TRUE)

but nothing gets replaced. What have I done wrong?

This `cat(gsub("imgsrc=", " – Sotos May 20 '19 at 12:59
What does cat do? – Sebastian Zeki May 20 '19 at 13:22
It's a `print` function. Have a look here: https://stackoverflow.com/questions/31843662/what-is-the-difference-between-cat-and-print – Sotos May 20 '19 at 13:33
Thanks @Sotos. The gsub needs to be applied to a column in a datafram so I think the cat function wont work as it concatenates all the results. Also why does cat work and gsub not work in this situation? – Sebastian Zeki May 20 '19 at 16:55
Your `gsub()` is working. Did you assign the result to `mydf$V1`? – Armali May 23 '19 at 09:25
