I have a large Excel file with SKU numbers (stock keeping units) and forecasts which can be mimicked with the following: Period <- c(1, 2, 3, 1, 2, 3, 4, 1, 2) SKU <- c("A1","A1","A1","X4","X4","X4","X4","K2","K2") Forecast <- c(99, 103, 128, 63, 69, 72, 75, 207, 201) PeriodSKUForecast <-

Hola, Belén. Podrías indicar qué error te da? En principio el paquete XLConnect funciona correctamente (tanto si lo descargas desde el CRAN como desde GitHub). Puede que no tenga que ver directamente con el paquete... alguna dependencia que no encuentra? Java? ... Un saludo, Miguel. ________________________________ De: R-help-es <r-help-es-bounces en r-project.org> en nombre de

Hola. Tengo una especie de "poltergeist"... a ver si alguien es capaz de echarme un cable.... sucede al usar los paquetes XLConnect (http://cran.r-project.org/web/packages/XLConnect/) y gWidgets (http://cran.r-project.org/web/packages/gWidgets/) simultáneamente en R 2.15.2 (de 32 bits bajo Windows 7) ... con la versión anterior (2.15.1), en las mismas condiciones, no pasa.

Dear R Users, I have to read data from many excel spreadsheets, all which have some frustrating formatting (lots of titles, headers, etc.). I am trying to work directly from source data and the number of the spreadsheets I would have to go through make reformatting one by one a pain. I have found lots of ways to read excel files, but my question is whether there is a way to only read

Hi, I have two questions on the function "readNamedRegionFromFile" in XLConnect pacakge. 1. In the documentation, # multiregion xlsx file from demoFiles subfolder of package XLConnect demoExcelFile <- system.file("demoFiles/multiregion.xlsx", package = "XLConnect") # Load a single named region into a single data.frame. df

Hola, Pensé que esto iba a ser trivial en R, pero me estoy encontrado muchos con mi problema en internet, y que las soluciones ofrecidas no terminan de funcionar. Estoy intentando leer un fichero .xls en ubuntu con los siguientes paquetes y nada: require(RODBC) conn = odbcConnectExcel("madrid.xls") # open a connection to the Excel file sqlTables(conn)$TABLE_NAME # show all sheets df =

Dear all, I got an issue trying to parse excel files in parallel using XLConnect, the process hangs forever. Martin Studer, the maintainer of XLConnect kindly investigated the issue, identified rJava as a possible cause of the problem: This does not work (hangs): library(parallel) require(rJava) .jinit() res <- mclapply(1:2, function(i) {

Hola, @javier, me gustaría no tener que hacer nada de forma manual, ni por fuera de r, rstudio. Es decir, el típico comando de linux que me convierta de xls a csv prefiero no usarlo. Me gustaría hacerlo todo desde R. @jorge -> Con RODBC me salta -> Error: could not find function "odbcConnectExcel" Lo que creo que es inevitable en Ubuntu

When I read a time hh:mm:ss from a excel sheet with gdata read.xls it is as expected. When I read the time with readWorksheet I get 1899-12-31 00:20:00 UTC. I would prefer XLConnect because it does not nee perl installed but the data coming with XLConnect is not usable.

Hola amigos, buenos días Esto sigue avanzando. Estoy ahora tratando de establecer la conectividad de R con Excel y he seguido dos viídeos en YouTube de una profesora llamada Bebilda que se explica muy bien.

Gracias Jorge por contestar tan rápido. Con gdata hago eso del path, y directamente con el fichero, lo vi en una web, y he intentado todas las opcioens que he visto. En vez de install.packages('rJava', type = 'source') he hecho install.packages('rJava') Ahora probaré, y lo mismo con scan y readLines. He visto en stackoverflow que mi problema puede ser actualizar java,
