similar to: gsub issue with consecutive pattern finds

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, e.g. with '*" repetition specifier. I used "?" for the optional character

Hi Iris, Thank you. Further, very nice solution. Best, Iago On 01/03/2024 12:49, Iris Simmons wrote: > Hi Iago, > > > This is not a bug. It is expected. Patterns may not overlap.

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 more about it here: https://www.regular-expressions.info/lookaround.html

Hello, I am trying to build a regex to extract vowels and consonants from a string. So far, I am able to extract the basic a-e-i-o-u sequence using the following extension to the String class: class String def vowels scan(/[aeiou]/i) end def consonants scan(/[^aeiou]/i) end end examples: >> "Mary had a little lamb".vowels => aaaiea >> "Mary had a

Hi, I am a new user of R using R 2.8.1 in windows 2003. I have a csv file with single column which contain the 30,000 students names. There were typo errors while entering this student names. The actual list of names is < 1000. However we dont have that list for keyword search. I am interested in grouping/cluster these names as those which are similar letter to letter. Are there any

Hi all, I downloaded R-devel as explicited in https://developer.r-project.org/SVNtips.html Then, I tried to install it through instructions in https://cran.r-project.org/doc/manuals/r-devel/R-admin.html#Installation (taking into account also https://stat.ethz.ch/pipermail/r-devel/2016-May/072777.html) So: export REPOS=https://svn.r-project.org/R export RTOP=~ #adjust as necessary cd $RTOP svn co

Dear all, I need to re-define some mathematical operators (+, *, /, etc) for an S4 class based on array. All references I have found (S Programming, Green Book) show how to define S3 methods for this (like in page 89 of S Programming for "-.polynomial"). What is the preferred S4 way for doing this? I hope I haven't missed some obvious piece of documentation. Many thanks, Iago

Hello, In my Debian 3.0 systems, packages are installed in two different places, namely /usr/lib/R/library and /usr/local/lib/R/site-library, depending on whether they come from debian packages or CRAN ones. Help pages for my own packages, installed in the second location, cannot find help pages from, for example, the base package via \link{}. I also tried specifying the package with

About the decisions: Actually, the same way dataedittext modifies the text colour not only of data, but also of row and column names, and dataedituser modifies the colour of all the borders, I think dataeditbg should modify the background of all the window, at least that "inside" those borders. Otherwise, any other option for the background colour on row and column headers would allow

Generally you'd use file() to open the file, then use readLines(), say inside a while() loop to read one `chunk' at a time. However, your example looks a bit strange. The possibility of empty line makes it a bit more complicated, by that last couple of lines seems to suggest that you could have a line of data follow by another line of data without variable label. If that's true, I

I have a chinese character on a data frame, but the output of printing it is its UTF-8 code. Concretely, the character is ? and the code is U+6703. Following the code I arrive to the instruction > base::format.default("?") which prints [1] "<U+6703>" I do not know which is the extent of this behaviour either if it follows on most recent versions of R.
