Dear R users, I'm happy to announce the release of version 0.3 of the udpipe R package on CRAN (https://CRAN.R-project.org/package=udpipe). The udpipe R package is a Natural Language Processing toolkit that provides language-agnostic 'tokenization', 'parts of speech tagging', 'lemmatization', 'morphological feature tagging' and 'dependency parsing' of

Hi R-helpers I'm looking for a vectorised function which does missing value replacement as in last observation carried forward in the zoo package but instead of a locf, I would like the locf function to add +1 to each time a missing value occurred. See below for an example. > require(zoo) > x <- 5:15 > x[4:7] <- NA > coredata(na.locf(zoo(x))) [1] 5 6 7 7 7 7 7 12 13

Dear R gurus, I am trying to overload some operators in order to let these work with the ff package by registering the S3 objects from the ff package and overloading the operators as shown below in a reproducible example where the "*" operator is overloaded. require(ff) setOldClass(Classes=c("ff_vector")) setMethod( f="*", signature = signature(e1 =

Hi there, I'm having trouble to compile the R + C/C++ codes for this project from Yahoo folks on latent factor models: https://github.com/yahoo/Latent-Factor-Models#readme After downloading the package from the site, I could not successfully *make* the files. Here is the message: ====================================================================================== sh-4.1$ make R CMD

Hi, Let me first stress that the success of the wiki is tight to how many users find it as a resource. And that users will only find the wiki for their problems if it has a higher PageRank. (I am using PageRank as an example, other search engines would do better if we can implement some changes overall.) If we take the HowTos/Laptops/Wireless page as an example, the page is not part of the

Does anybody know of these samba packages? http://ftp.cvut.cz/samba/samba-latest.tar.gz AFAICS they are faked and contain some kind of rootkit (you can see this in the history below. the server this history is from is taken offline for security reasons, and nobody is there till 7th Jan I can't give you more details) > 144 w > 145 cat /etc/issue > 146 uname -a > 147

Hi useRs, This is not so much a help request as it is a request for feedback about the possibilities of using Natural Language Processing (NLP) techniques on the r-help archives for a more 'effective' retrieval of answers. A few points that may capture what I'm trying to get at: 1) R has an emerging set of packages for NLP and text mining. Is it possible to provide the r-help archives

There is also the OptimizeR project on R-forge http://r-forge.r-project.org/R/?group_id=395. Other related projects are there also, but I'll let their authors speak for themselves. Stefan Theussl did a good job in the Task View, but it is from last June, and it would be a monumental effort to keep up to date with all the work going on. We're "almost" ready to put some of our

Estimados compañeros: Estoy interesado en el NLP, así que, al hallar el post State-of-the-art NLP models from R <https://blogs.rstudio.com/ai/posts/2020-07-30-state-of-the-art-nlp-models-from-r/>, gracias a Carlos Ortega, me puse con ilusión a leerlo. Sin embargo, tengo problemas con lo más básico, la instalación del paquete *transformers*. No puedo

Hi I'm quite new to optimization algorithms and I could use some advice or pointers. I'm using ?optim (method L-BFGS-B) to optimize a function over a 60-dimensional parameter space. The function itself takes about 1 to 6 minutes to compute. It finds an optimum after 6 tot 24 hours, depending on the problem I need to solve. For me, speed is an issue and I would like to reduce this to 1

Dear useRs, I very much like the effect display of the proportional odds model on page 29 (Figure 8) of the following paper by John Fox: http://socserv.mcmaster.ca/jfox/Papers/logit-effect-displays.pdf It really gives a very concise overview of the model. I would like to use it to illustrate the proportional odds mixed models we fit here for a project on Diabetes but I can't seem to reproduce

Hi, We recently switched from R2.7.0 to R2.8.1 but having problems tracking down this 'invalid multibyte character' encoding issue. Can someone point us how to solve this? > sessionInfo() R version 2.8.1 (2008-12-22) x86_64-unknown-linux-gnu locale:

One other mod to Ferret I''ve found useful is to add the following line at the top of the each_hit() block in Search::IndexSearcher.search: score = yield( doc, score ) if block_given? This allows a block attached to a search call to adjust document scores before documents are sorted, based on some (possibly dynamic) numerical factors associated with the document, e.g. the number

Dear R-users, Does anyone of you have binary files for the packages rpart.permutation, snow and rsprng. I would like to use them in my classification tree. I know they are still at the 0.x development stage, though. Where can I get information on how to compile tar.gz files? I'm using windows XP with R 2.1.0. Thanks, Jan --------------------------------------------------------------------

Hello R folks, I'm hoping the answer to the question in the subject line. I have in the past used SAS PROC NLIN and PROC NLP to carry out nonlinear optimizations. I'm wondering if there is analogous ways for doing this using R. If so, could someone please point me to some literature that would help me examine this further? Thanks very much.

Estimados Una pregunta, ¿Que posibilidad hay que esté instalado todo correctamente, pero algo cambie en entorno de python, el cual al ser buscado por R esté dando problemas? Hace años que no utilizo macOS, pero se me ocurre que un programa coloque en entorno adecuado para él, pero al mismo tiempo este toque al entorno requerido por R.

Dear All, Does anyone use S or R for statistical natural language processing (NLP)? All I have found so far is a package called EMU (http://www.shlrc.mq.edu.au/emu/emu-splus.shtml) which is a speech wave-form processing package. What I'm looking for are routines to support text processing, text categorization, word sense disambiguation, text understanding etc. In particular, I would
