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.

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 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

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 (an underscore between each pair of consecutive vowels)?

Hello, I have been trying to use by to create a means table, but receive the error " by(xx, list(subjs, cons, vowels), mean) Error in Summary.data.frame(..., na.rm = na.rm) : only defined on a data frame with all numeric or complex variables" when the data frame consists of three factor columns (subjs, cons and vowels) and 5 numeric data columns. The output I'm looking for is a

Hello, I have a vector x containing letters ("a", "b" etc.). Now I want to convert it to factor and group some letters into one common level. If I do it by factor function, giving the same label names for all values I want to group, it doesn't work: > x<-letters[1:5] > x [1] "a" "b" "c" "d" "e" >

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

First, I'd just like to thank the Speex community, and Jean-Marc especially, for their great work. I'm developing a VoIP library (which uses IAX, the asterisk protocol) as the network protocol. I've been putting off integrating Speex for a while, as things have been working pretty well so far with GSM. (for those interested, the code is at iaxclient.sourceforge.net). However,

Hi I have been tying to install the followings gems in order to add code syntax highlighting to my application: -Oniguruma -Ultraviolet -Harsh Unfortunately I have been running into the the following errors when running "gem install oniguruma ultraviolet" Building native extensions.

Hello Guys , Can anyone explain me how to use Oniguruma in ruby 1.9.2 , I guess in ruby 1.9.2 its a default library so there is no need to install externally?

Hello, I am not expert in wavelet. i am working with a discrete dataset in 3D. I applied the D4 wavelet transform to each dimension sequentially. I made some analysis in the transformed space and i detected some interesting vowel. My question is. How is it possible to map a 3d coordinate in the transformed space to the related coordinate in the 3d original dataset? (i think that probably one

A student entered some data with text characters like epsilon and alpha. On her Windows system, the Greek letters did not display properly in a plot. There were some ordinary ASCII instead.

are there plans to add "de-essing" as part of the speexenc procedure, to make it possible to use lower quality compression without getting those horrible computer-like "ess" sounds in the finished result? like if you say "someone said the sun is shining", there is a lot of ess sounds, and these will sound "computer-ish" at vbr qualities below 9. i know
