Oh, wait a second. I misread your original post. Please ignore my
truly incorrect suggestion.

Here's another *incorrect* way to do it -- incorrect because it will
not always work, unlike Iris's correct solution. But it does not
require PERL type matching. The idea: separate the two vowels in the
regex by a character that you know cannot appear (if there is such)
and match it optionally,
Hi Iris,
Thank you. Further, very nice solution.
Best,

Hi Iago,
This is not a bug. It is expected. Patterns may not overlap. However, there
is a way to get the result you want using perl:
```R
gsub("([aeiouAEIOU])(?=[aeiouAEIOU])", "\\1_", "aerioue", perl = TRUE)
```
The specific change I made is called a positive lookahead, you can read

Hi all,
I tested next command:
gsub("([aeiouAEIOU])([aeiouAEIOU])", "\\1_\\2", "aerioue")
with the following output:
[1] "a_eri_ou_e"
So, there are two consecutive vowels where an underscore is not added.
May it be a bug? Is it expected (bug or not)? Is there any chance to get
what I want
Hello R helpers,
I get a problem using gsub() function.
I have the following text :
text - INFILTRATION INF_BASE
AIRCHANGE=1
Then my code is :
original - INFILTRATION INF_BASE \n AIRCHANGE=1
replace - INFILTRATION INF_BASE \n AIRCHANGE=3
new_texte -
Hello Thibault Charles,
I have the following text :
text - INFILTRATION INF_BASE
AIRCHANGE=1
becomes:
text - INFILTRATION INF_BASE\nAIRCHANGE=1
original - INFILTRATION INF_BASE \n AIRCHANGE=1
There are spaces around \n. That's why text != original
Try
original - INFILTRATION

Hello Thibault Charles,
I have the following text :
text - INFILTRATION INF_BASE
AIRCHANGE=1
becomes:
text - INFILTRATION INF_BASE\nAIRCHANGE=1
original - INFILTRATION INF_BASE \n AIRCHANGE=1
The backslashes in the patt argument need to be doubled since \ is a
special regex character. Or it may work to set fixed =TRUE.
Either:
original - INFILTRATION INF_BASE \\n AIRCHANGE=1
replace - INFILTRATION INF_BASE \n AIRCHANGE=3
new_texte - gsub(patt=original,replace,text)
Or:
Hi Charles,
It's not clear to me what you mean by doesn't work.
test - Interesting 1\nPoint\n
cat(test)
Interesting 1
Point
test1 - gsub(ing 1\nP,ing 3\nP, test)
cat(test1)
Interesting 3
Point
Cheers
