Hello, I am relatively new to R and would like to access the document my pointer is pointing to in the following line of code. Need some help. #install.packages('xml2') library('xml2') pg1 <- read_html("www.msn.com") str(pg1) ptr <- pg1[[2]] [[alternative HTML version deleted]]

...te, me ha ayudado. Sobre la utilización de la función geocode con ciudades con tilde, me dio Carlos Gil Bellosta anteriormente la idea de utilizar iconv para transformar la cadena de búsqueda a UTF-8, y yo lo utilicé para intentar transformar el output de html_table sin resultado: capitales <- read_html(" https://es.wikipedia.org/wiki/Anexo:Capitales_de_provincia_de_Espa%C3%B1a_por_poblaci%C3%B3n ") capitales <- html_nodes(capitales, "table") capitales <- html_table(capitales[[1]])$Ciudad capitales <- iconv(capitales, to = "UTF-8") En la referencia que me ha...

Dear Experts , I am using R with Spark on Windows and now there is a need to move to Ubuntu. I wanted to know if most of the packages that are available on windows , would they be available on Ubuntu/Linux? If not can I compile the source code of those package ? Has any one of you used the packages on Ubuntu ? Thanks in Advance.

Estimados Hace un tiempo que no uso rvest, corrí un código viejo, anda sin problemas, escribo el nuevo y hay algo que me olvide. Básicamente desde el navegador de internet selecciono el xpath, copio y pego este en R, pero me sale el siguiente error. > text <- Pagina.R %>% + html_nodes(xpath='//*[@id="content"]/p')%>% + html_text() >

Hola a todos: Las versiones oficiales de R no son versiones beta, sino versiones "definitivas" convenientemente testadas. Los paquetes disponibles en el servidor de CRAN están testados contra la versión actual de R. Mantenerse en una versión anticuada normalmente conduce a la pérdida de funcionalidad, errores de dependencias entre versiones de paquetes nuevos etc. En R, actualizar
