leer ficheros excel en R en Ubuntu
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.

Exportar datos en formato de Excel
Hola. En mi caso, no he podido resolver los problemas con el Java para usar XLConnect, que en los papeles me parece el mejor.
