Búsqueda de palabras en una variable de R
Buenas, Tengo un vector de 40 palabras (marca) y necesito saber si en una de las variables del data.frame (datos) se incluye alguna de esas 40 palabras. Si se incluye alguna de ellas, me gustaría crear una variable dummy siendo 1 que incluye alguna palabra y 0 que no incluye. ¿Qué paquete me recomendáis? ¿Cuál sería el comando a ejecutar? Gracias!

Tibble o data.table?
Tienes razon de que hay una serie de paquetes que lo usan, pero me da que vienen impulsados por Rstudio desde el paquete tidyverse... Yo me resisto a usarlo. Me parece que queda mas limpio, pero no se porque no le pillo la gracia...Quizas sea el apoyo de Rstudio lo que me tire para atras... ________________________________ De: Carlos Ortega <cof en qualityexcellence.es> Enviado: miércoles,

problema con shiny
Muchas gracias Miguel-Ángel he probado la opción de la consola de R y sigue el problema, en este caso intenta mostrar en la pantalla del navegador la salida del programa pero se cierra R, supongo por tanto que se aborta el proceso.

Building GC on statepoint-example
Jordon, I just submitted a change to the docs to hopefully address your confusion.  Can you take a look and let me know if you have further questions?  Start with the revised Stack Map Format section. Philip p.s. I just submitted this and it'll take a few minutes to refresh.  In the meantime, you could look at the diff for 346405. On 11/2/18 2:52 PM, Jordan Rudd via llvm-dev wrote:

Tibble o data.table?
Buenas Os queria preguntar que ventaja le veis a las tibbles frente a los data.table, ya que para mi, quitando el uso de librerias como tidyr o purrr, en el resto prefiero usar data.table. Me parece igual de potente y mucho más rápido, y no le veo las supuestas ventajas, pero quiero conocer vuestra opinion. Gracias Jesús [[alternative HTML version deleted]]

add only the 1st of May with POSIXct
Thank you Rui for your code. I basically understood all your suggestions. I am using an old version of R (version 3.6.3, installed in a server I am not allowed to control), and the new pipe operator does not work. I tried to run your code without the "|>" operator, but I get an error when I use apply. Could you please expand your code without the pipe operator? Thank you again

opus library issues
Many people have run opus on small embedded devices. It may be the case that your VLA support isn't providing enough stack. You may want to try using the pseudostack mode which will instead put that memory on the heap and give you better control over making sure you have enough available.

OpenSSH Certificate Extensions
Hello: I am working to implement certificate-based authentication for some internal applications. It would be very helpful to be able to pass information server-side by specifying some custom options via the Extensions of the signed certificate, allowing the authenticity of the options to be verified readily. However, I have not been able to find too much for specifying behaviors, etc.

But is that not adviced in the manual[1]? I am also in the process of setting up dovecot behind a haproxy. Still testing with this.
